MRJ4M-QUAD features an LCD display with backlight, configured as 1 row of 4 digits and 2 rows of 7 digits. It accommodates 3-phase 4-wire and 1-phase 2-wire electrical connections. This device, with a power consumption of 8VA max, acts as a monitor for electrical parameters of up to 4 loads (3-phase) and 12 loads (1-phase). It operates self-powered and supports measurements of power (Active, Reactive, Apparent) and energy (Active, Reactive, Apparent). Communication occurs via RS485 and MODBUS RTU protocols. CT Primary is adjustable from 1A to 10kA, while CT Secondary is 330mV through Plug-n-Wire CT output. PT Primary spans 100 to 10kV, and PT Secondary ranges from 100V to 500V AC (L-L). The rated input voltage is 60 to 300V AC (L-N) and 104 to 520V AC (L-L). The supply voltage is 60 to 300V AC, self-supplied (V1, N), at 45/65Hz. With dimensions of 70 x 90mm, it’s designed for Din Rail mounting and holds CE RoHS certification.
