Features:
Digital display DC voltage detection, control the relay output.
DC 6~80V relay interface bo-ard with 2 Bu-ttons for easy operation.
With clear LED display, convenient to check the value.
Adjustable Voltage Detection Range: DC 0~99.9V.
When the measured voltage is lower than the lower limit or higher than upper limit value, the relay works.
Can be used for voltage detection switch, Ba-tte-ry over/under voltage protector or discharge meter.
Comes with a cover for protection.

Specifications:
Material: P-CB + ABS
Working Voltage: DC 6~80V
Voltage Detection Range: DC 0~99.9V
Error: +/-0.1V
Working Current: 8mA/24V(relay open, LED displays OFF about 4mA/24V); 58mA/24V(relay closed)
A set of transformations(normally open/normally close, NO/NC)
Contact Load: NO: 30A/250V AC or 30A/30V DC; NC :20A/250V AC or 20A/30V DC
Attention: Because high voltage DC electric arc damages relay contact,
so the electric load above DC60V load current is less than 10A.
Contact Resistance: ≤100mΩ(1A 6VDC)
Mechanical Durability: 10 millions Electricity durability: >100,000 (20A~250VAC)
Operating Temperature: -40~85°C
