| FEATURES | |
|---|---|
| Overvoltage protection OVP | The output voltage is limited to 15% over nominal output voltage by a extra regulated circuit |
| Under voltage alarm | A built in alarm changes to alarm state if the converter output voltage drops 10% below nominal output. The DC OK LED is also controlled by the alarm circuit. The alarm has a relay output with both [NO] and [NC] function. The relay rating is 30V 1A(ac & dc) |
| Reverse input voltage Protection | On input code 24 and 48 the reverse voltage protection is provided by a parallel diode. This diode is only intended to blow and external input fuse. On input code 110 and 220, the reverse voltage protection is provided by a series diode. The converter will never start. |
| Inrush current limit | On input code 110 and 220 the inrush limit circuit is always active thus acting at voltage dips below the stop level >10ms. On input code 24 and 48 this function is optional. |
| Adjustment & measurement | Output voltage adjust potentiometer and output voltage measurement points are accessible from the front panel. |
| Conformal Coating | the PSC series is conformally coated to withstand non-condensing tropical environment. |
| OPTIONAL FEATURES | |
|---|---|
| Wider input range | The PSC600 series can be supplied with wide inptu range to meet train or mobile applications demands |
| Built in series diode - C | Series diode on the output, which is mounted inside the case. Use this option when the output is connected in parallel with other power supply to achieve redundancy |
| Built in series diode with resistor - CR | The CR option automatically balance the load between 2 or more paralleled PSC600 units. Used in hotswap. |
| Remote Sense - S | The voltage sensing can be put at the load to compensate for voltage drop. The sense circuit is a standard feature on 5V outputs. |
| Inrush Current LImit | On input code 24 and 48 the inrush limit circuit is optional. This option affects the input voltage range. The circuit is always active thus acting at voltage dips below the stop level > 10ms. |
| Higher insulation on output - E2 | Output/case 2.5kVAC for 12 to 125Vdc |
| Over current shutdown - OCSD | The PSC600 series can provide over current during a limited time. The OCSD circuit shut down the unit when a preset time has passed. This delay can be pre-set between 100ms to 3 seconds. |
