Sine wave inverter power supply for electric power safeguard, for electricity, communication system design, is a kind of will power and battery power into AC power conversion device of purification, to provide computer and other electrical equipment with continuous AC power, to prepare the city electrical instability and power. Can also prevent the public power of various aberrations, such as supply voltage drop, surge voltage, peak voltage and radio frequency interference.

Inverter power source technology characteristics:

Øinverter unit is microprocessor controlled SPWM technology, pure sine wave output waveform, pure

Øunique technology of dynamic current loop control to ensure the reliable operation of inverter

Øthe load adaptability is strong, including a capacitive, inductive, mixed load

Øoverload capacity and strong shock resistance ability, can withstand the full load boot

Øhas input, output, under voltage, over voltage, over temperature, overload, short circuit protection function

Øautomatic switching, unattended operation can be achieved

Østable performance, safety and reliability, long service life

ØLCD display, the operation data stick out a mile

Principle diagram of

1, when the normal, electricity through the switching circuit direct load power supply,

2, when the city electricity input abnormal, by the switching circuit switching to DC input to be transformed into pure AC, to a load power supply;

Work environment

The use of this product please as far as possible to meet the following requirements:
