High-Frequency Backup UPS

Includes peak absorption circuit, alternating voltage stabilizing
circuit, charging circuit, inverter circuit, and electric supply inverter
conversion circuit. Highlighting a high reliability design, the inverter
circuit adopts PWM-MOS inverter, charging utilizes a rapid switching
circuit.

Features:
1) High-speed microprocessor control
2) Plastic case, compact and unique
3) High-frequency PWM and double conversion technology for small volume
and convenient operation
