Description

EM-07E-DIN ( User Manual ) ➜

The EM-07-250D-DIN allows for real-time monitoring of 3-phase voltage and current, showing per-phase apparent power (S) and frequency (F), along with minimum, maximum, average, and demand values. Its 71.5 × 61.5mm glass LCD display offers a sharp, easy-to-read interface, while the menu system is user-friendly and password-protected for secure access.

The meter is equipped with adjustable protections for over/under voltage, current, and frequency, along with phase-to-phase or phase-to-neutral fault protection. It also features phase sequence detection and includes 1 relay output for alarms or automation triggers.

Designed for systems with 3-phase voltage and 3-phase CT inputs, this model supports remote communication via RS485 (Modbus RTU), making it ideal for integration into SCADA or energy management systems. With its included CTs and compact DIN rail form factor, installation is quick and efficient.
