Control Modules

Zeefax's unique experience and expertise has allowed the company to design, manufacture, supply, repair and calibrate many of the control modules used on Ross Hill and Hill Graham systems. As well as the standard analogue AC and DC control modules, we are able to repair Hill Graham's Field Regulator modules, DFC (Digital Frequency Controller) and VFD (Variable Frequency Drive) modules. Furthermore, we have developed and brought to market an exact replacement for Ross Hill's obsolete AutoSync module with an improved digital design which occupies the exact same footprint and is exactly pin compatible.
