HC 12 F Local EHT Controller
Description
A load control device intended for automatic and remote discrete control of user power, measuring the current consumed (using external measuring transformers) and voltage on three phases.
The device can be used both independently and as part of automated process supervision and control systems. The product may be installed in outdoor control cabinets.
Data exchange with the monitoring / control system is provided via RS-485/CAN serial interface.
Any setting and modes, and firmware updates are possible via a USB service port.
The device is registered with Russian Instrument Register #67073-17.
