Stabilizer servo motor HT9000S(1~20KVA)
HT9000S series high precision auto voltage regulator power supply mainly consists of contact autotransformer, servo motor, and automatic control circuit. When grid voltage is unstable or the load varies, the automatic control circuit drives the servo motor in compliance with a variety of output voltage, adjusts carbon brush position on the contact autotransformer, makes output voltage adjusted to be rated value, and reaches a steady state.
Description
HT9000S series high precision auto voltage regulator power supply mainly consists of contact autotransformer, servo motor, and automatic control circuit. When grid voltage is unstable or the load varies, the automatic control circuit drives the servo motor in compliance with a variety of output voltage, adjusts carbon brush position on the contact autotransformer, makes output voltage adjusted to be rated value, and reaches a steady state. HT9000S series products introduce advanced technology, adopt energy-saving ring transformers and use integrated circuits and high-quality components, which make them featured with a small footprint, lightweight, high-efficiency, and energy-saving, no additional distortion of the output waveform, stable performance, and reliability.
Automatic restart, turn-on delay, time-delay system, and high & low voltage cut-off that provide efficient and reliable protection for home electronic appliances against voltage problems
Ring transformer structure, small footprint, minimum magnetic leakage, low noise
High adaptability to all kinds of non-linear load such as inductive load and capacitive load
High power density, high cost-effective, wide application
Multilayer structure carbon brush with long service time and convenient daily maintenance
No serious vibration or jolt in the installation place
When the power outage of the power grid is restored, the regulator can be automatically restored the power supply
