Brief Introduction
As the name implies, our PRND electrical specialized power inverter is a kind of intelligent product that is especially developed for electrical equipment, and it shows some outstanding properties as illustrated below.

Features
1. This product makes use of microcomputer's CPU for intelligent control, and the control circuit is simple and reliable, realizing fast response to the changes of external environment.

2. The SPWM (Sinusoidal Pulse Width Modulation) technology is used to output pure sine wave with stable frequency, stable voltage, low noise and low harmonic distortion.

3. Our electrical specialized power inverter possesses good load capacity and excellent load compatibility, while the built-in bypass switch ensures more stable and continuous power supply.

4. The leading-edge reflection noise reduction technology is applied at the DC input end, avoiding interference with other communication devices that share the same DC panel. As for the AC input end, multiple filtering technology is adopted to eliminate interference from mains supply, thus meeting the system's demand for master AC power supply.

5. This product could set either AC or DC as the master power supply.
a. For AC type master power supply, when mains supply is available, mains supply works to drive electrical appliances, and DC voltage of battery will be automatically converted to AC to provide power when mains supply outage occurs.
b. For DC type master power supply, when mains supply is available, AC power is supplied by converting DC voltage, and when DC input fails, mains supply will take over automatically.

6. The electrical specialized power inverter is scientifically designed, and during running, it can cut off DC voltage and switch to AC bypass automatically without affecting normal working of external loads. This brings great convenience when the battery needs maintenance or replacement.

7. When the battery voltage is too high or too low, relevant protection will be activated to cut off voltage output. After that, the battery voltage is adjusted to normal level and voltage output is continued automatically. For voltage output failure caused by overload, power supply will also be automatically restored 50 seconds after the overload problem is solved. This makes our product extremely suitable for unattended communication base stations.

8. Our product could be started by AC, but it can't start up if there is any load at output end. Moreover, communication function is realized, allowing users to get the real-time condition with the help of monitoring software.

9. Our electrical specialized power inverter has two groups of passive dry contacts that are used for DC input failure and AC output failure, respectively.
