Datasheet

GSP500 series 

## 500W **Fancooled** 180W **Convection cooled** 

**AC-DC power supplies** 

The GSP500 has been designed to offer a full 500W of output power in a very small mechanical footprint, whilst still providing peak power to 650W, a 5V standby output with 2 Amps of current capability and an input standby power draw of <1W when the inhibit is activated. 

Approved for both IT and medical applications the series has output versions from 12V to 48VDC and can be supplied as a U channel for system cooling or with optional very quiet integral fans (-EF). These fans are intelligently controlled to provide the most optimised acoustic noise in the system and further more the GSP500 can provide up to 180W without fan cooling, thus allowing fans to be switched off during periods of lower system loading.

Notes: 

1. Remove suffix -EF (EndFan) for use with integral system cooling. 

2. Peak power available for 100ms maximum with a 10% duty cycle. The average power in a period should be equal or less than the normal power. 

3. For optional current share version, add suffix ‘P’, e.g. GSP500PS24P or GSP500PS24P-EF.

## **Thermal considerations** 

In order to ensure safe operation of the PSU in the end-use equipment, the temperature of the components listed in the table below must not be exceeded. Temperature should be monitored using K type thermocouples placed on the hottest part of the component (out of direct air flow). See below for component locations. 

|Temperature measurements (at maximum ambient)|Temperature measurements (at maximum ambient)|
|---|---|
|Component|Max temperature °C|
|**T1 coil**|+120°C|
|**L3 coil**|+120°C|
|**Q7 body**|+120°C|
|**Q102 body**|+120°C|
|**C20**|+105°C|
|**C102**|+105°C|



## **Service life** 

The estimated service life of the GSP500PSxx Series is determined by the cooling arrangements and load conditions experienced in the end application. Due to the uncertain nature of the end application this estimated service life is based on the actual measured temperature of a key capacitors with in the product when installed by the end application. The worst case of the two figures should be taken as the indicative service life in 24/7 operation. 

The graph below expresses the estimated lifetime of a given component temperature and assumes continuous operation at this temperature.
