The TND series single-phase contact AC 220v voltage stabilizer is composed of a servo motor, a control circuit, and an auto-voltage regulator (or a compensation transformer). It has small size, light weight, high efficiency, wide voltage regulation range, and no waveform distortion. And other advantages. It is equipped with functions such as over-voltage (under-voltage) protection, delay (selection) protection, and fault protection. It has two-way voltage indication, complete functions, safe and reliable. It is widely used in household electricity, industrial and agricultural production, scientific research and medical and health fields.

Scope of use: suitable for computer network engineering equipment, household appliances, medical equipment, scientific research units, measurement equipment, factory calibration benches and other equipment supporting use.

220V Voltage Stabilizer Working principle:

1. Structure: This product is mainly composed of a contact auto-coupling voltage regulator, a sampling comparison amplification control circuit, an output voltage protection circuit, a servo motor and a rotating arm.

2. Work: When the input voltage is unstable or the load changes, each phase sampling circuit samples separately, compares it with the set benchmark, amplifies it, and executes the required direction rotation of the motor according to the comparison result, driving the rotation of the voltage regulator. The arm adjusts the voltage so that the output of each phase remains unchanged, thereby achieving voltage stabilization. The main circuit schematic diagram is shown below:

SHANGYU POWER CHINA®220V Voltage Stabilizer Feature And Application

Features:

1. High quality output voltage

The 220v voltage regulator can work without interruption, the voltage regulation process is smooth, and there is no transient power loss. The output voltage regulation accuracy is high and is usually factory adjusted to 220V+3% for single-phase and 380V±4% for three-phase.

2. The input voltage has a wide working range and strong load characteristics.

This machine can operate normally within a wide input voltage range and has satisfactory load characteristics.

3. High safety factor

Over-voltage and short-circuit protection (protected by fuses or high-breaking small circuit breakers) can automatically cut off the output if the output voltage is too high, greatly improving the safety factor of the machine and effectively protecting terminal electrical equipment.

4.Long life

Above 2K, a high-breaking small circuit breaker is used, which has reliable protection against load and short circuit; the voltage stabilizer uses the latest successfully developed high-performance carbon brush, which greatly extends the normal service life of the voltage stabilizer.

Precautions

1. The 220V voltage regulator should avoid severe vibration, harmful gas corrosion and liquid inflow.

2. For the connecting wire of the voltage regulator, please equip it with a connecting wire (copper core) with sufficient current capacity according to the rated power (≤5A/mm

3. There is a grounding device inside the voltage regulator, and the wire connected to the outside should be reliably grounded. The grounding wire must not be removed arbitrarily or left ungrounded.

4. If the output voltage deviates greatly from the rated value, please adjust the trimmer potentiometer in the control circuit board by yourself. Turning it clockwise will increase the output voltage, and vice versa will decrease the output voltage.

5. Keep the inside of the machine clean. Dust will hinder the rotation of the gears and affect normal use. It should be removed in time to keep the contact surface of the carbon brush and coil clean. Ensure that the carbon brush spring has sufficient pressure to avoid sparking at the contact surface between the carbon brush and the coil.
