Product Overview:
The relay protection test power supply is mainly used for low-voltage trip test and 80% low-voltage test power supply in high-voltage switch operating circuits, and also for the self-starting performance test of switching power supplies used in protection devices, testing the starting voltage of each switching power supply.
Functional Features:
1. Adopts advanced switching power supply technology, small size, light weight, low loss, short-circuit protection, with millisecond timer function, can be used to test switch action time, built-in digital voltmeter display, easy to use, precise continuously adjustable output, full-range voltage stabilization;
2. Built-in temperature-controlled cooling fan, which not only effectively dissipates heat but also effectively extends fan life;
3. Overheat automatic shutdown protection, output overvoltage, overcurrent, and short-circuit protection;
4. Soft-start on power-on delay to avoid output voltage overshoot;
5. High-frequency transformer isolation, safe and reliable.
