KET-PMM-300 is a Single-phase energy meter with backlit LCD display with integrated touch keypad.
Particularly indicated for active energy metering and for cost allocation in applications up to 100 A (direct connection), with dual tariff management availability.
It can measure withdrawn and input energy or be programmed to consider only the withdrawn one.
Housing for DIN-rail mounting, with IP51 front degree protection.
The meter is optionally provided with pulse output proportional to the active energy being measured, RS485 ModBUS port or M-Bus port.
