Product introduction



MGR-SCR3-120LA

THREE PHASE POWER REGULATOR (SIMPLE TYPE)

Product Image - MGR SCR3 120LA

Features
● Linear phase-shift control circuit with good stability and high precision
● Vacuum welding technology with good quality and long service life
● Modularization with high pressure resistant, safer and more reliable
● Miniaturization with convenience for installation, wiring and etc.

Parameters
● Rated current: 25A,40A,80A,100A,120A
● Rated voltage: Power regulator--three phase 380VAC (three-phase four-wire); Air cooled fan--220VAC
● Control signal: 4-20mA,0-5VDC,0-10VDC
● Control frequency: 50Hz/60Hz
● Output mode: phase output
● Operating environment: Ambient temperature below 45 °C, ambient humidity below 90% RH

Notice

● The input circuit of the main circuit adopts three-phase four-wire connection, no phase sequence requirement.

● SCR is a high current component, so please be sure to tighten the (A1, B1, C1) and (A2, B2, C2) terminals, otherwise it will heat up the terminals and then burn out the SCR.

● When the three-phase load adopts the Y-connection method, the neutral point of Y must be connected to the neutral line; if the neutral point of Y is not connected to the neutral line, the three-phase load needs to be relatively balanced.

● When the module is used for the load with load power greater than 15 KW, it is recommended to use a suitable heat sink, and apply thermal grease between the heat sink and the SCR backplane, as well as cold air to cool down.

● Module protection: Please use the semiconductor high speed fuse to protect the load and module from overcurrent.
