ZTY-Series fully automatic AC regulated power supply, is driven by a servo motor to complete auto regulator voltage regulator features a universal AC power supply. View>>

JJW, JSW series precision purifying AC power supply is according to Cooper's "Sine energy distribution" theory, combining with efficient network of integrated design of broadband filter. View>>

When the device power factor is not 1, the input current waveform distortion can occur, resulting in harmonic currents. View>>

It refers to the relative output voltage variation. It is a percentage, and the smaller the better. When the input voltage or the load changes, the output voltage of UPS will increase or decrease. View>>

A device used to charge the battery. Note: 1.The larger capacity of the battery, the greater charging current it required, otherwise, it will take a long time to charge. View>>

Micro-Control Unit which adopts computer hardware and software technology. View>>

A standard interface which can realized asynchronous transmission between the multi-station internet ,remote transmission computers and other equipments. View>>

Usually refers to diesel or gasoline generator. It is one of the ways that UPS works. It normally contains rectifier (AC / DC), battery, inverter (DC / AC) and bypass switch. View>>

The physical quantity used to quantify people's sense to sound. The unit of which is dB. The noise of UPS is typically 40-80dB. View>>

When the reverse current is large enough, the device's reverse voltage is stable at the nominal value, and forward characteristic is the same as diode. View>>
