1. Tested input voltage:
Can detect AC/DC universal: AC/DC 10-300V, internal dip switch AC/DC input
Detection mode: select either overvoltage detection OV/undervoltage detection UV by dialing code
2. Adjustable parameters on the panel (dual knob setting):
PICK UP (action trigger value): continuously adjustable from 1.0 to 3.0 times the reference voltage
HOLD (Delay Hold Time): 2% to 30% gear, corresponding to a delay of 0.5 to 30 seconds for action locking, and a delay reset after voltage recovery
3. Output contact specifications:
Contact form: Single group SPDT conversion contact (1NO+1NC)
Contact capacity:
AC250V: resistive load 2A
DC24V: 0.3A (minimum reliable current 7mA)
Mechanical lifespan: ≥ 10 million cycles, electrical lifespan ≥ 100000 cycles
Action indicator light: The red OPER action indicator light on the panel is triggered to light up
