Pure Sine Wave Inverter Description
The Pure Sine Wave Inverters are used for Telecommunication Power and Utility Power Supply equipments. You could choose the different Voltage and Power of the inverter you need.
1. With micro-CPU control, the circuit is simple and reliable. High efficiency >85%. Adopting SPWM technology, with the output is pure sine wave with stabilized voltage and frequency,filtering noise and low distortion.
2. 1-4kva pure sine wave inverter built-in bypass switch, it can quickly switch between the mains and the inverter.
3. It can work without DC power. This function allows to use the inverter in advance, and install the battery.
4. Support communication function; RS232/RS485/RJ45 interface for choose. Provide three groups of passive dry contact: DC input failure, the mains failure and AC output failure alarm.
5. Mold design alone, coated paint, beautiful and generous, light weight. 1U, 2U, 4U or 8U 19 inch rack mounting design, easy to use.
2 working type— AC power type and DC power type:
1. AC power type means the city power supply is main when the city power is normal, when city power is off, inverter comes into work state.
2. DC power type means the inverter power supply is mainly when the city power is normal when inverter power is off; city power comes into work state automatically.
3. It can be turned off DC power in working condition and auto switched to the AC bypass, which will not affect the power supply to the load, and it is convenient maintenance and replacement of the battery.
4. When it is overload, the inverter will shut off the output. After recovering the normal load power within 50 seconds, the power will auto recovery output. This function is suitable for the unmanned communication base station.
Pure Sine Wave Inverter Features
1) These pure sine wave inverters can be used as telecom inverter for the switch, computer rooms , networks and other communication equipment.It can provide 220V or 110V AC power to the load or as mains special emergency power to prevent the serious consequence of electricity interruption by converting 24V or 48V batteries. It can also be used in some important devices to reduce the loss of city electric voltage pollution.
2) These inverters also can be used in solar system for the home application.
