ACREL Multi-Circuit Power Meter with RS485 Modbus
ACREL Multi-Circuit Power Meter with RS485 Modbus is a DIN rail multi-circuit power meter for monitoring electrical parameters across up to four three-phase circuits. It uses split-core current transformers for practical installation and provides LCD display and RS485 Modbus-RTU communication. Optional modules can add temperature and residual current measurement or digital input and output functions.
