LP-KWM Series Kilowatt Hour Meters
with optional RS485 MODBUS® RTU

The LP-KWM series of electronic kWh meters has variations for single phase, two phase, three phase 3 or 4 wire, balanced or unbalanced systems.
In addition to the LCD display there is a pulse output for use with data loggers or similar electronic recorders and controllers.
The compact circuitry employed allows these meters to be housed in a standard 3M or 4M DIN rail mount case.
