Compact Smart Meter (KSM

Smart 3-phase meter for compact installations with LTE-M connectivity

The Compact Smart Meter (KSM) is a space-saving, versatile energy meter that combines metrology and gateway functionality in a single device. With a width of just 4 DIN units, the KSM is ideal for installations where traditional smart meters are too large or impractical—without compromising on measurement accuracy or connectivity.

Designed for 3-phase 4-wire or 3-phase 3-wire networks, the KSM also supports single-phase operation when only one phase is connected. Its integrated LTE-M modem and embedded eSIM enable remote communication with utility back-end systems and energy management platforms.

The KSM features a built-in RS485 port (optional Modbus), an optical configuration port, and P0/P3 interfaces for WAN communication. It does not include a P1 or P2 port. The user interface includes a dot-matrix LCD display, metrology LEDs, and a front-facing button. Spring clamp terminals ensure a quick and secure installation.

Compact yet powerful, the KSM is ideal for non-residential applications such as EV charging infrastructure, traffic installations, and grid monitoring.
