HMK7 controller (hereafter referred as controller) is a controlling device used to combine with SHM-1 motor
drive unit to realize electrical control of switching operation for on-load tap changer.
Controller can indicate the operation status of tap change and tap positions.
Controller provides complete terminals for BCD code output (contact capacity: 0.5A 120V / AC or 1A 28V / DC)
and remote action signal input (non-potential contacts).
Thus it can realize remote monitoring of OLTC. It can also be connected to host via RS485 communication
interface for remote control and monitoring of on-load tap changer.
