Product description
The electric pressure regulator is composed of an imported silicon steel ring iron core, which is wound around a single-voltage winding. A plurality of carbon brushes mounted on the brush holder closely match the polished surface of the coil under the action of spring pressure, and the motor drives the carbon brush. The voltage is adjusted by sliding on the polished surface of the coil. The pressure regulator is composed of an imported silicon steel ring iron core, which is wound around a single-voltage winding. A plurality of carbon brushes mounted on the brush holder closely match the polished surface of the coil under the action of spring pressure, and the motor drives the carbon brush online. The voltage is adjusted by sliding on the polished surface of the ring; if automatic voltage regulation is required, a voltage can be set in advance (any fixed point can be set within the adjustment range), and the potentiometer can be adjusted to the required voltage point through the external voltage. Observe the set voltage value. After the voltage value is set, the voltage regulator will automatically adjust to the set voltage. If the external voltage fluctuates, it can also automatically adjust the stable voltage;

Working principle: The carbon brush closely matches the polished surface of the coil under the action of the spring pressure, and the motor drives the carbon brush to slide on the polished surface of the coil for voltage adjustment. The utility model has the advantages of small loss, high efficiency, small magnetic leakage, low noise, strong instantaneous overload capability, no waveform distortion and the like;
