EFS-9253 25A Three Phase Power Controller
EFS is an electronic, time-proportional controller with two or three power thyristor outputs with zero-crossing triggering for 3-phase voltage. is a power regulator.
EFS converts an analog signal into a pulse/pause ratio between on and off power. When the control signal is for example 5V, the power is turned on for 50% of the adjustable time.
There are traces of corrosion on the base connection plates of the products that have formed over time. These traces do not affect the use of the product in any way.
- To prevent noise in radio and TV (emc), power, sine it opens and closes at the zero point of the curve.
- EFS has a built-in P-regulator and forms a compact power regulator, for example for underfloor heating systems.
- EFS has a signal converter and voltage or current can be connected to an external regulator with an output.
- EFS has a built-in relay that allows doubling the power by using two equal heating elements.
EFS provides great effects Used when there is a desire for accurate and noiseless regulation, e.g. heating batteries in ventilation systems. EFS can also control heating cable, heating foil and electric radiators.
EFS can be mounted with the cooling profile located inside the duct/unit or outside the panel wall.
The period time can be set from 1-40 sec, which means the EFS can be used to control infrared heating elements.
Led Indicators
MAIN LED 1 (green): Indicates that voltage is connected
OUT LED 2 (green): Indicates that voltage is present on the load.
LIMIT LED 3 (yellow): Steady light means restriction is active (no effect), flashing means sensor fault
STEP LED 4 (green): Lights up when the step relay is activated
