• Timing on/off: The MT-400/3K-330 can be used to perform timing on/off, which can reduce energy consumption and improve power supply reliability.

Working Principle

The MT-400/3K-330 device is based on the principle of using a voltage regulator feedback circuit to control the output voltage. It contains a number of components such as a voltage bridge, a diode bridge, a regulating device, a current transformer, an indicating device, and etc. The working principle of this device is as follows:

1. The device measures the instantaneous AC voltage through the bridge set, inputs it to the high-frequency voltage-regulating circuit, and the voltage regulator provides feedback to the operating circuit.
2. When the output voltage change exceeds a certain range or the instantaneous voltage is out of the set output range, the voltage regulator in the circuit will automatically regulated, which in turn adjusts the output voltage so that the output voltage changes within the set range.
3. The current transformer connected to the input end of the regulating system detects the load over-current signal, converts the signal into a proportional current signal, and sends it to the voltage regulator, so that the output voltage will be adjusted and limited by the voltage regulator in time.

By using the MT-400/3K-330, the voltage output of the system can be stabilized, the safety and reliability of the power supply can be effectively improved, and the energy consumption can be reduced.
