Power Inverter

1. Product Introduction of The Power Inverter

​

Power inverter power supply is specially designed for substation and power plant. It is used for power telecontrol, communication, monitoring, accident lighting, etc., it can also provide uninterrupted power for AC lubricating pump, AC fan and water pump of power plant. The product models include: HD220-500VA, HD220-1000VA, HD220-2000VA, HD220-3000VA, HD220-4000VA, HD220-5000VA.

2. Product Feature And Application of The Power Inverter

Product Features:

CPU control is adopted, and the line is simple and reliable.

Using SPWM pulse width modulation technology, the output is pure sine wave with stable frequency and voltage, noise filtering and low distortion.

Built in bypass switch, fast switching between mains power and inverter.

It is Divided Into Mains Supply Type And Battery Supply Type:

A) Mains power supply type: When there is mains power, it is in mains power output. When mains power input fails, it will automatically switch to inverter output.

B) Battery main supply type: When there is mains power, it is in inverter output. When DC input fails, it will automatically switch to mains power output.

It is allowed to cut off the DC in the startup state and automatically switch to the mains bypass, which will not affect the power supply of the load and facilitate the maintenance and replacement of the battery.

When the load is overloaded, the inverter power supply turns off the output, and the power supply automatically recovers the output 50 seconds after the overload is eliminated. This function is especially suitable for unattended communication base stations.

Support communication function, provide RS232 interface (Pin2, 3 and 5), and use monitoring software to understand the working condition of power supply in real time. (Note: This function is not available for 500VA models in this series).

Provide two groups of passive dry nodes for DC input fault (RS232 pin6, 7) and AC output fault alarm (RS232 pin8, 9).
