PS-18 universal adjustable power source is available for power system protection, high-voltage device test and circuit test. It adopts high-performance Cortex-M3 core and 32-bit ARM processor, with fast data processing and high precision. Rotary encoder is employed to adjust voltage, which is convenient, speedy, safe and reliable. 128x64 lattice LCD screen is used for operator-computer interaction, with all-Chinese display and large quantity of information, which is very convenient. Voltage is displayed using high-accuracy digital meter with high precision. Voltage adjusting range is wide; current stability accuracy is high; capability to withstand current is strong. Tripping and closing switch signals are output separately, which can test action voltage value. Our power supply also integrates three-channel intelligent millisecond meter function, which can be started by signal from power supply or external digital electrical quantity. The millisecond meter can be started by three external digital inputs at the same time, and it can also measure them.
PS-18 can be used as/for
Ø 80% voltage test source for relay protection device and switch operation circuit;
