Hundreds of thousands of on-off cycles cannot be run or counted by hand; surge-then-rated load combination conditions (such as 64A surge followed by 16A rated) exceed ordinary life testers; high-temperature loaded ageing has no bench, and eight samples queued one by one miss every deadline.
8 independent stations (3 high-temperature at 25-150C settable + 5 ambient) with one-key switching; per JB/T 3022-2021 micro switch, surge plus rated combination per UL61058-1 (e.g. 64A surge then 16A rated) with smooth transition; surge duration 20-5000ms freely settable; loads AC250V/50Hz inductive R+L parallel, 50Ax3, 70Ax3, 100Ax1, 30Ax1, PF0.4-1 adjustable; current 0.1-100A continuously adjustable, 0.1A resolution; servo motor plus lead-screw/linkage drive with adjustable rate and stroke on linear guides; PLC + touch screen + PC control with 30 programmable routines; voltage and cycle settings, live current/voltage/cycle display, test and alarm count logging, pause and per-station reset; Ethernet/RS232/RS485/USB interface for data download; over-voltage, over-current, over-heat, short-circuit and air-pressure monitoring protection; insulation AC2000V/50Hz 1min no breakdown; display 0.1V/0.1A/0.01PF, class 0.5 meters; continuous duty with forced air cooling, noise under 60dB.
Type testing and life sampling at proximity/micro/limit switch plants; UL61058-1 surge combination verification for appliance switches; high-temperature loaded ageing at automation component factories; third-party switch life testing
