ENEPRO FCR04100 VRCL1P-1 SCR VOLTAGE REGULATOR & CURRENT LIMITER PCB

Enerpro FCR04100 paired with VRCL1P-1 is a single-phase SCR firing and voltage regulation PCB assembly for thyristor power control systems, widely used in industrial rectifiers, motor controllers and marine power panel applications. This regulator sub-board VRCL1P-1 plugs onto FCR04100 firing PCB, providing voltage regulation and current limiting function. It accepts voltage feedback from voltage transformers and current feedback from CT or hall-effect sensors, adjusting SCR firing angle to stabilise output voltage and restrict maximum current. It has adjustable potentiometer for span setting, built-in signal conditioning and noise filtering, with self-diagnosis for circuit fault detection.

This unit is a vital power electronics spare part for industrial SCR power control cabinet overhaul. The power control spare part monitors output voltage and current continuously, limits current and regulates voltage for rectifier loads. The power control spare part works together with FCR04100 firing board to control SCR phase angle. The power control spare part can replace faulty regulator PCB to restore stable voltage supervision and current limiting protection.

It delivers reliable SCR phase angle control & voltage/current regulation for industrial power conversion systems. The SCR phase angle control & voltage/current regulation adjusts thyristor firing timing to maintain stable output voltage. The SCR phase angle control & voltage/current regulation prevents overload damage to transformers and motor loads. The SCR phase angle control & voltage/current regulation supports flexible parameter adjustment for different power conversion requirements.

VRCL1P-1 PCB is plugged as daughter board on FCR04100 SCR firing board. It is original Enerpro spare part for thyristor power control system maintenance.
