Changhong Pure Sine Wave inverter
Adopting intelligent microcomputer CPU control technology to ensure the reliability of control circuit and quick-response to environmental changes. Adopting SPWM pulse-width modulation technology, the output of changhong inverter is CVCF (constant voltage& constant frequency), noise filtering and low distortion factor pure sine wave.Changhong inverter has good load carrying capacity and load compatibility. Besides, built-in bypass switch greatly improves its continuity and reliability.Changhong inverter has good selected mating, which can cut off DC power supply in switch-on state and automatically switch to commercial power bypass power supply. It is more convenient to maintain and replace the rechargeable batteries, but has no effect on supplying power to load.If battery voltage is too high or too low, the overload indicator light alarms and output power supply cuts off, but the output power supply can be automatically switched on when the battery voltage recovers to normal value or the overload is removed 50s later. Therefore, Changhong inverter is applicable for unattended communication base station. Changhong inverter supports communication function, which adopts monitoring software to monitor the system working situation timely. In addition, the load electric quantity can be monitored through its indicator on the inverter.
