Low Frequency Power Inverter with Charger

Brief Introduction
The PRC-PSW low frequency power inverter with charger is especially designed to provide high quality AC electricity for houses, business sites, office rooms and other places.

It is a universal product that is suitable for various kinds of inductive, capacitive and resistive loads, making it applicable for televisions, refrigerators, computers, electric fans, air conditioners, cash registers, washing machines, electric tools, water pumps, microwave ovens, incandescent lamps, energy saving lamps, etc. Meanwhile, it also shows good stability, pure sine wave output and excellent overload capability. In general, it is a new generation intelligent type product, and all the functions will work automatically once it's started.

Advantages
1. The exclusive phase tracking function with utility frequency makes this low frequency power inverter match perfectly with generators.
2. The transfer time from DC to AC, namely from the point when main power fails to the point when inverter output is provided, is less than 5ms, while there is no transfer time when main power is restored.
3. The front panel could be equipped with LED or LCD display, and the battery type should be selected via the LCD display including lead-acid type, gel type and vented type.
4. The three-step charging technology divides charge profile in three phases which are bulk charge, absorption charge and float charge, and this is very helpful to improve the overall performance.
5. This low frequency power inverter is characterized by high working efficiency, high power factor, excellent load capacity and no noise, while it also realizes automatic switch between battery mode and mains supply mode.
6. To ensure safe running, many protections are achieved, such as over voltage protection, low battery protection, overload protection, overheating protection, short circuit protection, etc.
7. Software monitoring and remote control are optional.
8. Aside from these, our product is able to work for quite a long time even under extreme environment. So, routers, servers, cash registers, automatic teller machines (ATM), cash recycling systems (CRS) and many other devices won't need restart when power failure occurs.

Applications
Depending on its features illustrated above, this low frequency power inverter has found a variety of applications in different fields, and the following are some typical ones.
1. Facilities in offices and public places
2. Home-use systems
3. Network transmission equipment
4. Manufacturing and control systems
5. Solar energy systems
6. Outdoor well drilling projects
7. Ships, trucks and industrial machines
8. Telecommunications, alarm systems, outdoor base stations
9. ATM, CRS, cash registers in supermarket, highway toll gates, fare collection systems for metro
