Overview |
| |
• MD Series standby power supply is designed for powering signal processing equipments in cable TV and telecommunication systems OUTDOORS. |
| |
|
| |
• Ferro resonant transformer, featuring complete ling conditioning, provides fully
regulated, reliable and uninterruptible quasi-square wave AC power. |
| |
|
| |
• Easy accessible front panel connections make installation and operation easy. |
| |
|
| |
• Smart LCD + LED display shows, simply but clearly, operating status and info-
mation of the power supply, as well as visible alarm. |
| |
|
| |
• Two micro-circuit breaker (MCB) located at the front panel are quite useful to cut off main power and battery immediately in emergency. |
| |
|
| |
• Pole & wall mount (PWM) and ground mount (GM) enclosures, provided for out-
door powering applications, are available as optional features. |
