Carevas DC 6~80V Voltage Detection Charging Discharge Monitor Relay Switch Controller with Case

Features:
Digital display DC voltage detection, control the relay output.
DC 6~80V relay interface board with 2 buttons for easy operation.
With clear display, convenient to check the value.
Adjustable Voltage Detection : 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, battery overunder voltage protector or discharge meter.
Comes with a cover for protection.

Specifications:
Material: PCB + ABS
Working Voltage: DC 6~80V
Voltage Detection : DC 0~99.9V 
Error: +/-0.1V
Working Current: 8mA24V(relay open, displays OFF about 4mA24V); 58mA24V(relay closed)
A set of transformations(normally opennormally close, NONC)
Load: NO: 30A/ AC or 30A30V DC; NC :20A/ AC or 20A30V DC
Attention: Because high voltage DC electric arc damages relay , 
so the electric load above DC60V load current is less than 10A.
Resistance: ≤100mΩ(1A 6VDC)
Mechanical Durability: 10 millions Electricity durability: >100,000 (20A~250VAC)
Operating : -40~85°C
