R-SPS6020 DC Bench Power Supply and Laboratory

Power Supply 0-60V 0-20A 1200W for Electronic

Load Control Board Testing

Key Features

1. Adjustable 0–60V DC Output for Electronic Load Control Board Testing

The NICE-POWER R-SPS6020 series provides adjustable 0–60V DC output for powering electronic load control boards during bench testing and development. Engineers can set an appropriate DC input voltage to check board power-up behavior, confirm basic operation, and investigate power-related issues under controlled laboratory conditions.

For electronic load control board testing, the power supply acts as the DC source for the board or its compatible input circuit. It does not function as an electronic load and does not independently verify the board's control logic or load-regulation performance.

2. 20A Output and 1200W Rated Power for Laboratory Testing

With a rated output of up to 20A and 1200W, the R-SPS6020 series supports compatible electronic control boards, power modules, and related test circuits that require a higher-power DC source. The adjustable output helps users match the supply to the voltage and current requirements of the device under test.

The actual output current depends on the connected load and selected operating conditions. Always keep the voltage, current, and total output power within the power supply's ratings and the control board's input specifications.

3. Four-Digit Voltage and Current Display with Power Readout

The digital display shows the power supply's output voltage and current, while the power display helps users monitor the power delivered to the connected board. These readings support routine checks during power-up, input adjustment, and troubleshooting.

The displayed readings are the power supply's output values. They do not directly indicate the electronic load control board's signal levels, control accuracy, switching waveforms, or load response. Use suitable external instruments when these characteristics need to be measured.

4. Constant Voltage and Constant Current (CV/CC) Operation

The R-SPS6020 series supports automatic switching between constant voltage (CV) and constant current (CC) operation according to the load and operating conditions. Users can set a suitable voltage and current limit to supply a compatible control board during bench evaluation.

CV/CC operation helps regulate the power supply output under different load conditions. It should not be confused with electronic load control, programmable load simulation, or automatic verification of a control board's protection functions.

5. Manual and Programmable Versions for Different Testing Workflows

The R-SPS6020 series is available in two versions to suit different operating preferences:

  • R-SPS6020 Manual Version: Uses an encoder knob for direct manual voltage and current adjustment. It is suitable for routine electronic load control board power-up checks, input voltage adjustment, and hands-on troubleshooting.

  • R-SPS6020-R Programmable Version: Intended for test setups that require programmable control. Confirm the supported control method and the exact purchased configuration before integrating it into a computer-controlled test system.

USB, RS-232, and RS-485 communication interfaces are optional configurations and must not be assumed to be included with every unit. Automated test sequences, data logging, and software integration should only be specified when supported by the confirmed configuration.

6. Output ON/OFF Control and Front/Rear Output Terminals

The R-SPS6020 series provides output ON/OFF control so users can enable or disable the DC output during setup and testing. Front-panel and rear-panel output terminals accommodate different connection and current requirements.

The front-panel output is intended for currents below 5A. For higher-current applications within the unit's rated capability, use the rear-panel output with appropriately rated cables and connectors. Check polarity and connection security before applying power to the control board.

Applications

1. Electronic Load Control Board Testing

Provide DC input power to a compatible electronic load control board for initial power-up checks and basic functional evaluation. Adjust the supply voltage to match the board's input requirements and monitor the supply's output readings during testing.

2. Electronic Load Controller Power-Up Verification

Use the R-SPS6020 series as a bench DC source when bringing up an electronic load controller or related control circuit. The supply helps provide the required input power, while a multimeter, oscilloscope, or other appropriate instrument can be used to check control signals and board behavior.

3. Power Control Circuit Development and Troubleshooting

Supply adjustable DC power to compatible power control circuits during prototype development, fault investigation, and laboratory troubleshooting. The manual version supports direct adjustment at the bench, while the programmable version may suit control-oriented workflows when the required control configuration is available.

4. Electronic Load System Research and Laboratory Evaluation

Support laboratory work involving electronic load control boards, DC power modules, and related power electronics circuits. The R-SPS6020 series provides the DC input source; a separate electronic load or other suitable test equipment is required when the test needs to apply a controlled load or evaluate load-response performance.

Why Choose NICE-POWER R-SPS6020 Series?

The NICE-POWER R-SPS6020 series combines adjustable 0–60V DC output, up to 20A current, and 1200W rated power for electronic load control board testing, laboratory power-up checks, and power electronics development.

Choose the R-SPS6020 for direct manual adjustment during hands-on testing, or consider the R-SPS6020-R when programmable control is required and the purchased configuration supports the intended control method. Both versions provide an adjustable DC source and output readings to support practical bench testing of compatible electronic control boards.

For a complete electronic load control board evaluation, pair the DC bench power supply with suitable external instruments and, where required, a separate electronic load. This allows the power supply to provide the input power while the other equipment performs the relevant signal, load, and performance measurements.

Important Note: Verify the control board's input voltage, polarity, current requirement, and power rating before connecting it. Do not exceed the supply's 60V, 20A, or 1200W ratings. Use the rear output terminals for currents above 5A with appropriately rated wiring. Communication interfaces are optional and must be confirmed before purchase. The R-SPS6020 series is a DC power supply, not an electronic load; electronic load simulation and direct control-board signal analysis require separate equipment.

All KUAIQU DC power supplies support basic battery charging. For dedicated long-term charging, our patented battery-charging model with independent BATTERY key and full charging protection is highly recommended.

A certain amount of ripple is normal for all switching DC power supplies. Ripple is a small residual AC component superimposed on the DC output and is an inherent characteristic of switching power supply technology. The typical ripple voltage of our power supplies ranges from approximately 100 mV to 300 mV, which is suitable for most general-purpose testing, maintenance, and electronic applications.

A: Minor fluctuations in the last displayed digit are normal and are typically caused by temperature drift within the electronic components. As ambient and internal temperatures change, small variations in the readings may occur. This falls within normal industry tolerances and does not affect the power supply's suitability for everyday electronics work, home repairs, DIY projects, or general testing. For applications requiring extremely high precision and ultra-stable output, a linear DC regulated power supply may be more appropriate.

This is normal and does not indicate a malfunction. The internal capacitors continue to hold a small amount of stored energy after the power is switched off. As the capacitors discharge, the display will gradually turn off, typically within 5–8 seconds.

In CV mode, the power supply maintains a fixed output voltage while the current varies according to the load. In CC mode, the power supply limits the output current to a preset value, automatically reducing voltage if necessary. CC mode is especially useful for battery charging, LED testing, and protecting electronic components.

This is normal behavior. The power supply contains internal filter capacitors that store electrical energy. When the output voltage is reduced, these capacitors require a few seconds to discharge, causing the displayed voltage to decrease more gradually than when increasing the voltage. Q: Why does t

Output ripple refers to small residual AC fluctuations present in the DC output. Lower ripple levels provide cleaner power, which is important when testing sensitive electronics, RF circuits, audio equipment, and precision instruments.

Yes, all DC regulated power supplies manufactured by KUAIQU support battery charging. However, if you mainly intend to charge batteries, I would highly recommend our patented DC power supply specially designed for battery charging. It comes with an exclusive dedicated BATTERY function key, and built-in specialized charging protection functions to safeguard your batteries during the whole charging process..

This is normal behavior. The power supply contains internal filter capacitors that store electrical energy. When the output voltage is reduced, these capacitors require a few seconds to discharge, causing the displayed voltage to decrease more gradually than when increasing the voltage..

This is normal and does not indicate a malfunction. The internal capacitors continue to hold a small amount of stored energy after the power is switched off. As the capacitors discharge, the display will gradually turn off, typically within 5–8 seconds..

This is a common operation issue for adjustable DC power supplies. Please follow the steps below to solve the voltage adjustment failure: Turn the current adjustment knob clockwise moderately to set the unit to constant voltage (C.V) mode; After confirming the power supply enters CV mode, turn the voltage adjustment knob clockwise, then you can freely adjust the output voltage value..

It is recommended to pre-adjust the voltage to around 5V before operation. This step prevents spark generation when connecting short-circuited loads, which effectively avoids safety accidents and other hidden electrical hazards..
