The power controllers set percentage of the power which is to be supplied to the actuator. Adjustment is by way of time. Depending on the percentage set by the duty ratio is selected interval. The time interval is programmable.
Power controllers have two control outputs. Relay output contactor is used to control the output voltage controls the power semiconductor switches.
The controller CRM is a digital version of the device.
The controller provided the percentage of power is displayed on the display and set the keys on the front panel.
The controller is programmable. You can set the time interval to control the range of 1 to 99 seconds. and select the output that will control the actuators (voltage or relay).
The basic parameters of power controllers are:
