• Four isolated channels for powering different circuits.
• High resolution 1mV and 1mA for precise tuning.
• Series connection up to 60 V or parallel connection up to 6 A.
• Auto-tracking function for synchronous channel changes.
• Electronic load shedding to protect devices.

How does a multi-channel power supply work?

You select a channel and set the desired voltage and current. The device stabilizes output parameters with high accuracy. Voltmeters and ammeters show current values. When the current setting is exceeded, electronic protection is triggered. The two main channels can be combined to increase voltage or current. You get laboratory power for any task.

Technical characteristics and functionality

Model GPD-74303S has two adjustable channels 0–30 V / 0–3 A. The third channel is adjustable from 0 to 5 V at a current of 0–3 A. Also, the third channel can operate up to 0–10 V at a current of 0–1 A. The fourth channel produces a fixed 5 V at a current of 1 A. The setting resolution is 1 mV and 1 mA.

Basic accuracy 0.03% for voltage and 0.3% for current. There are four digital indicators on the panel (2 voltmeters, 2 ammeters).

Connection modes: series gives 60 V at 3 A. Parallel gives 30 V at 6 A. Auto tracking function synchronizes channels CH1 and CH2. Electronic load disconnection protects the powered device. Built-in memory cells (4 pieces) store settings. The USB interface connects the device to a computer. Power source weight 7 kg.

The source is ideal for powering flight controllers and ESCs. It is used for testing battery assemblies. Allows you to check the operation of servos and receivers. Four channels replace multiple power supplies. High precision is important for tuning sensitive electronics.
