A. Introduction
Blazer series is an off-line power System that has a square wave output. It prevents impulse,
surge, sag and power outage situations. It provides the UPS output load with a reliable
source. It has the following functions:
1.
Booster:
If the commercial line is under voltage, the Booster will rise the UPS output voltage to
1.18 times its input voltage.
2.
Buck:
If the commercial line is over voltage, the Buck will reduce the UPS output voltage to
0.85 times its input voltage.
3.50/60Hz Automatic Frequency Selection:
The output frequency will automatically match the input frequency (50 or 60Hz).
4.Communication Port(RS232+open collector):
Computer interface with RS232 communication and remote shutdown capacities.
5.Data line/telephone line protect:
The unit provides RJ11 receptacles to provide transient voltage surge suppression
(TVSS) for data line or telephone line.
