The range includes oscilloscopes, signal generators and spectrum analyzers. GW Instek also produces multimeters, power supplies and LCR meters. Products are used in laboratories and production facilities around the world.
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.
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.
