DC-DC Converter Testing

Key Features

0-60V Adjustable DC Output for Converter Input Testing

The R-SPS6040S provides a continuously adjustable 0-60V DC output, allowing engineers to set different input voltage conditions when evaluating DC-DC converter circuits. It is suitable for development and bench testing where stable and adjustable DC power is required.

0-40A High-Current Output for Power Conversion Testing

With output capability up to 40A and 2400W, this DC Power Source can supply higher-current test conditions for DC-DC converter prototypes and power conversion circuits. The high-power output provides greater flexibility when testing converters under different load requirements.

Real-Time 4-Digit Voltage, Current and Power Display

The 4-digit display provides clear readings of output voltage, current, and power during testing. Engineers can monitor the actual operating condition of the DC-DC converter while adjusting the power supply, making test results easier to observe and evaluate.

Precision Encoder Adjustment for Controlled Settings

The precision encoder knob allows smooth and accurate adjustment of output parameters. This is useful when a DC-DC converter needs to be evaluated under different voltage or current settings during circuit development and bench testing.

M1-M4 Memory Function for Repeated Test Conditions

The M1-M4 four-group Memory Function allows commonly used power supply settings to be stored for repeated testing. This helps reduce repeated manual adjustments when engineers need to switch between frequently used DC-DC converter test conditions.

OCP and OVP Protection for Safer Converter Testing

Built-in Over Current Protection (OCP) and Over Voltage Protection (OVP) help protect the connected test circuit when abnormal current or voltage conditions occur. These protection functions provide an additional layer of safety when testing DC-DC converter prototypes and power conversion circuits.

Output ON/OFF Control for Convenient Test Operation

The independent Output ON/OFF function allows the DC output to be enabled or disabled without repeatedly changing the configured voltage and current settings. This makes it convenient to start, stop, and repeat converter tests at the workbench.

Panel Lock for Stable Test Settings

The Panel Lock function helps prevent accidental changes to power supply settings during testing. It is particularly useful when a DC-DC converter is being evaluated under a defined voltage and current condition.

High-Current Rear Output for Full-Power Applications

The rear output connection is designed for high-current applications and supports the rated output capability of the R-SPS6040S. For DC-DC converter testing that requires higher current, the rear output provides a practical connection option for the test setup.

USB, RS232 and RS485 Interfaces

The R-SPS6040S is equipped with USB, RS232 and RS485 interfaces, providing connectivity options for test bench integration and equipment communication requirements.

Applications

DC-DC Converter Prototype Testing

Provides adjustable DC input power for engineers developing and evaluating DC-DC converter prototypes under different voltage and current conditions.

Power Conversion Circuit Evaluation

The 0-60V, 0-40A, 2400W output range supports bench evaluation of power conversion circuits where different DC input conditions need to be tested.

Converter Input Condition Testing

Engineers can adjust the DC Power Source output to examine converter performance under different input voltage and current conditions, helping identify changes in circuit behavior during development.

Repeated DC-DC Converter Testing

The M1-M4 Memory Function helps store frequently used settings, making repeated converter testing more convenient when several test conditions are used during development.

High-Current Converter Testing

The 0-40A high-current output provides additional capacity for DC-DC converter circuits that require higher input current during laboratory and engineering evaluation.

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..

A: Our banana plug adopts cross-slot design. If the plug becomes loose, use a screwdriver to slightly pry open the metal slot, which can make the plug clamp tighter and connect more safely..

Some models of our KUAIQU DC regulated power supplies support programmable control. They are equipped with USB, RS232 or RS485 communication interfaces and adopt the Modbus protocol. You can realize remote control easily by using our self-developed PC software. If you need programmable control but are unsure whether a specific model comes with your required communication interface, please feel free to contact us via email: kuaiquinstrument@163.com.
