The 1031 is available as a Custom OEM model only. Contact the factory for more information.

The model 1031 is a single-phase, zero-cross SCR power controller that controls the electrical power applied to a single phase load by a distributive control technique in which the time frame varies as a function of on and off cycles.


The power applied to the load is linear with respect to the command signal. The model 1031 uses potentiometer or a 1/5V command control.


The model 1031 is available with current ratings from 10 to 70 amps and voltage ratings from 120 to 575Vac.


The model 1031 is a compact and economical power control solution for industrial applications that require high reliability and long life.


The fast solid state switching of the model 1031 provides superior performance over relays, contactors and other slower cycling controllers by reducing temperature variations associated with the longer ON/OFF cycles of those devices.


The result is a more precise control of the heating process and extended heater life. Zero-cross control generates minimal RFI noise, virtually eliminating the possibility of interference Approvals with other electronic equipment.


Line voltage compensation greatly reduces load power variations that result from line voltage changes. This feature provides a more constant load power independent of line voltage variations.
