| The MPD-425V is a metal enclosed DC-DC converter that can handle 48V DC input. The MPD-425V DC-DC converters features four DC
outputs (5V/-5V/12V/-12V), 250 watts output rating and built-in long life ball-bearing fan. The MPD-825V is designed for use in telecommunication applications, ATX personal computers, workstations
or equivalent systems.
This power supply is
typically used in -48V
DC applications. |

| Power Good Signal |
When power is turned on, the power good signal will go high 100mS to 500mS after all output DC voltage are within regulation limits. |
| Power Fail Signal |
The power fail signal will go low at least 0.5ms before any of the output voltage fall below the regulation limits. |
| Overload Protection |
For some reasons the power supply fails to control itself, so the built-in over voltage protection circuit will shut down the outputs to prevent damaging the external
circuits. The trip point of crowbar circuit is around 5.7V to 7.0V. The power supply will go into hiccup mode against short circuit or over load conditions, and will auto-recovery while faulty
conditions and removed. |
