3027M is available as a Custom OEM model only. Contact the factory for more information.


The model 3027M is a three-phase, zero cross power controller that controls two legs of the three phase supply. The average output voltage is proportional to the command signal. Sync-Guard and Trans-Guard features are built in.

 

The 3027M will accept a 4 to 20mA command signal. When this signal is absent, the controller will automatically use the internal manual command pot to control the output.

 

If an external potentiometer is desired for remote operation, terminals are provided for this purpose. For full range control by the external pot, the internal pot must be turned to minimum. The internal pot may be used to set a minimum level of command for the external potentiometer.
