SRS Rigging AHD12-LV 12 Channel Chain Hoist Controller 63/3

The AHD-LV Digital Hoist Controller was designed to control up to 12 electrically compatible motors, either separately or simultaneously – controlled via CMCseries Digital Cable Remote Controller.

The device is equipped with unique APA (Automatic Phase Align) module, which guarantees that the motors are moving in the same direction on any align of input phases. If any line wire is disconnected, the hoist controller stops to ensure safe operation.

Another feature of AHD-LV is the AVM (Automatic Voltage Metering) module. This module checks main voltage for AC 400V +-20%, star configuration and protects the hoists in case of problem with main voltage.

The unit will NOT go into the safe function if:

one phase is missing
there is under-voltage on lines
there is over-voltage on lines
All electrical components carry their own individual CE and comply with the European Directives.

The AHD-LV has an additional key switch for the Group-stop function. When active, the MCB trip of any hoist will cause an E-STOP on all connected hoists.
