MOTOR WINDING HEATER CONTROLS
The MWH Series provides a cost effective solution these problems by preventing condensation built-in motors.
By applying a low level current to the motor windings during extended shut down periods, the MWH Series keeps AC motors warm and moisture-free.
Easy to install
Whether retrofitting an existing starter installing a new one, the MWH Series is easy to apply. Just wire it in parallel to the magnetic starter’s line and load connection, connect the necessary auxiliary contacts and installation is complete.
Output voltage is factory set to maintain +5°C to 10°C differential above ambient temperature. This adjustment can be used to trim the control as required for each application.
In addition to built-in fuse protection, the MWH Series features and RC snubber circuit across the SCR which protects it from any rapid rate of change in the system voltage. A metal oxide varistor (MOV) protects the unit against voltage spikes for reliable, maintenance-free operation.
