SPS-E305 30V 5A 150W Adjustable DC Power Supply 

Product Overview

The KUAIQU SPS-E305 30V 5A 150W Compact Adjustable DC Power Supply is designed for electronic circuit testing, sensor development, embedded systems, small electronic modules, and low-power prototype testing.

With an adjustable output of up to 30V and 5A and a maximum output power of 150W, the SPS-E305 provides controlled DC power for electronic circuits that require stable and adjustable voltage and current during development and testing.

Its compact 10 × 18.5 × 8 cm design and weight of less than 1 kg make it well suited for electronics development benches, engineering desks, educational labs, and space-limited test setups.

Compared with higher-current power supplies, the SPS-E305 focuses more on controlled power for electronic circuits and small devices, making it a practical choice for engineers, students, and electronics developers.

Key Features

30V / 5A Adjustable DC Output

The SPS-E305 provides adjustable output up to 30V and 5A, with a maximum output power of 150W.

The power supply automatically limits the available voltage and current combination according to the 150W maximum power rating.

For example, it can provide up to 30V/5A, making it suitable for applications that require higher voltage with moderate current rather than high-current DC loads.

This makes the SPS-E305 a practical 30V 5A DC power supply for electronic circuits, modules, sensors, controllers, and prototype devices.

Compact 150W Bench Power Supply

Measuring only 10 × 18.5 × 8 cm and weighing less than 1 kg, the SPS-E305 is designed for workspaces where a conventional laboratory power supply would take up too much room.

It can easily fit alongside oscilloscopes, multimeters, development boards, soldering equipment, and other electronics tools.

The compact design makes it suitable as a small bench power supply for electronics development.

Encoder Knob Control

The SPS-E305 uses encoder knobs for voltage and current adjustment.

Press the encoder to select the desired digit and rotate the knob to change the value. The 3-digit display provides 0.1V voltage resolution and 0.01A current resolution, allowing users to set output values more conveniently during circuit development and testing.

Automatic Cooling

The integrated cooling fan automatically starts when additional heat dissipation is required, helping maintain stable operation during extended testing.

If the power supply becomes excessively hot, stop operation and allow it to cool before continuing.

Wide 100–240V AC Input

The SPS-E305 accepts 100–240V AC, 50–60Hz ±10%, making it suitable for use with different electrical standards without requiring an external transformer.
