| FEATURES | |
|---|---|
| Overvoltage protection OVP | The output voltage is limited to 15% over nominal output voltage by a extra regulated circuit |
| Voltage Sense | External output voltage sense used when the voltage regulation at the load is critical. The sense can compensate voltage drops up to 5% of the nominal voltage |

| Voltage Alarm | Over / Under voltage alarm built in relay changes state if converter output voltage is not with 90% to 115% of nominal output. User selects NO or NC relay function. The relay is rated 30V 0.5A |
| Inhibit input / Power down | This input allow remote start and shutdown of the converter by a signal voltage of 5 to 12V. Max 35mA |
| OPTIONAL FEATURES | |
|---|---|
| Series Diode | Use the series diode output when the output is connected in parallel with other power supplies to achived redundancy. The output current is derated with 10% on 24 to 48V outputs. |
| Conformally coating | For environment with high non condensing humidity, max 98% RH |
| Inrush current | Inrush current limit with NTC, reduces the inrush current during start up. The input votlage range will be affected. Only available on C & D inputs. |
