Smart Voltage Meter (Adopting A.C. Sampling, set ratio through key on panel)

Applicationt: 

auto

Production Description:

GENERAL

Adopting A.C. Sampling this series meters can measure electir-cal parameters of the net such as current,voltage,power,power factoretc.And set ratio through key on panel. It contains RS-485 communication interface,adopts Modbus protocol.It is designed to transform electrical parameters signal into standard DC analog signal output,or alarm output with 2 relays.
