2 AC input, DC input and AC continuous output are completely isolated;

2 High output voltage accuracy;

2 high load capacity.

Dedicated communication line UPS designed specifically for the communications industry, suitable for a 48V (or-48V) DC power (DC-screen) program-controlled switches, computer rooms, network, billing, server and Emergency light places. 48VDC power in a place where the DC inverter power supply used to power important electrical equipment than the conventional uninterruptible power supply (UPS) consists of the following advantages:

1. To avoid duplication of investment in batteries and reduce system maintenance and reduce system operating costs;

2. To the program-controlled switching power supply of the DC panel generally VRLA batteries are used, since the DC-screen, high reliability, long life, thus adding a DC power inverter, power supply reliability and longevity of its greatly increased. The batteries in conventional UPS is often no maintenance, no monitoring, but prone to damage the battery had failed to discover the circumstances;

3. 48V DC panel capacity of the room are large, so when using inverter power supply, the grid can provide power long enough after the AC power supply time.
