AcuDC 240 Overview
The AcuDC 240 series energy meter for DC applications includes renewable energy generation.
The AcuDC 240 Series is a line of DC power meters that measures the voltage, current, power and energy parameters. They are used for monitoring and controlling energy flow in DC systems.
Readings are displayed on the brilliant 3 line black backlight LCD display. All AcuDC models offer integration with external systems using MODBUS RTU protocol and an on-board RS485 serial communication port.
Optional analog, digital, relay and alarm output is available via field-swappable plug-in communications modules.
The line has been field-tested for accuracy, versatility, durability.
