OF-METER
The OF-METER is an RS485 power meter that is simply used to measure power consumption. It is designed for installation in a switchboard (size 3 DIN modules). Its advantage is the PE15 function - a function for monitoring PV overflows to the distribution network. The device is equipped with a relay output R, which is permanently switched on and after exceeding the defined 15-minute maximum, the relay disconnects and thus ensures e.g. emergency disconnection of the PV plant to prevent unauthorized overflow (e.g. in case of failure of the standard control of the installed technology.

- Consumption measurement: OF-METER accurately measures electrical energy consumption, individually per phase, including power factor, positive and negative energy
- Calculation of 15-minute energy averages - negative and positive (supply to the grid and consumption from the grid)
- Relay output activated according to overflow / energy consumption value
- Can also be used to disconnect load when reserved input power of the metering point is exceeded
- Basic current range is 0-65A, current probes with 9mm diameter
- Optionally, current probes with 16mm, 24mm, and 35mm diameters are available
- Extended current range -150 to +150A (measuring resistors must be changed from 44 ohms to 22 ohms - solder pads J1, J2, J3 on the board)
