Selec MRJ4M


MRJ4M offers an LCD display with backlight, featuring a display configuration of 2 rows with 4 digits and 1 row with 7 digits. Designed for both 3-phase 4-wire and 1-phase 2-wire electrical connections, it includes a pulse output feature. Notable functionalities encompass RJ45 connector current input, self-powered operation, energy measurement (Active/Reactive), and Max Demand Power calculation. Communication takes place through RS485 and MODBUS RTU protocols. It supports CT Primary programming from 5A to 10kA and CT Secondary at 330mV. PT Primary is adjustable from 100V to 10kV, while PT Secondary ranges from 100V to 500V AC (L-L). The rated input voltage spans 60 to 300V AC (L-N) and 104 to 520V AC (L-L). With self-supplied abilities (V1, N) and a supply voltage of 60 to 300V AC (45/65Hz), the device is compactly sized at 70 x 90mm and is suitable for Din Rail mounting. It holds certifications for CE RoHS and MID compliance.
