KUAIQU SPPS305D Regulated DC Power

Supply 0-30V 0-5A 150W with Encoder

Adjustment for Embedded Device

Development

The KUAIQU SPPS305D Regulated DC Power Supply provides stable and adjustable DC power for Embedded Device Development, embedded system testing, and electronic prototype verification. With 0-30V, 0-5A, and 150W output capability, this DC bench power supply combines precision encoder adjustment, full-color LCD display, M1-M4 memory storage, and independent output control to help engineers establish reliable power conditions during embedded device development.

Designed for engineers, developers, and laboratory users, the SPPS305D supports repeated testing and debugging workflows by allowing users to adjust, monitor, and recall commonly used voltage and current settings when developing embedded devices, control boards, and electronic modules.

Key Features

Encoder Adjustment for Precise Embedded Device Power Setup

The SPPS305D Regulated DC Power Supply features a precision encoder adjustment knob for accurate voltage and current setting. During Embedded Device Development, engineers can smoothly adjust power parameters when testing different operating conditions for embedded boards, electronic modules, and prototype devices.

M1-M4 Memory Storage for Efficient Development Testing

The built-in M1-M4 memory storage function allows users to save four groups of commonly used voltage and current parameters. During embedded device development, engineers can quickly recall saved settings when testing different prototypes or repeating verification procedures, improving testing efficiency.

Stable 0-30V 0-5A Output for Embedded Applications

With adjustable output of 0-30V and 0-5A, the SPPS305D provides flexible DC power for embedded device development tasks. Engineers can set suitable power conditions for different embedded circuits, development boards, and electronic modules during design verification and functional testing.

LCD Display for Real-Time Operating Monitoring

The full-color LCD display clearly shows:

  • Output Voltage (V)

  • Output Current (A)

  • Output Power (W)

During embedded system development, users can monitor real-time power conditions and observe changes when adjusting device operation or testing different circuit configurations.

Output ON/OFF Control for Development Safety

The independent Output ON/OFF control allows users to switch power delivery without changing stored voltage and current settings. This function is useful when developers need to repeatedly power embedded devices during debugging, modification, and verification processes.

Panel Lock and USB 5V/2A Auxiliary Power

The panel lock function helps prevent accidental changes to voltage or current settings during testing. The integrated USB 5V/2A output provides additional power support for compatible USB-powered devices used alongside embedded development equipment.

The banana plug adopts cross-slot design. Pry the metal slot slightly open with a screwdriver to make the plug clamp terminals tighter and safer..

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 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..
