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 2Amps of current
capability and an input standby power draw of < 0.5W when the inhibit is activated.
Approved for both IT and medical applications the series has output versions from 12V to 48V
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 accoustic noise in the
system and further more the GSP500 can provide up to 180W without forced cooling, thus
allowing fans to be switched off during periods of lower system loading.

Models & Ratings
Notes
1. Remove suffix -EF (EndFan) for use with integral system cooling.
2. Peak power available for 100 ms 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.

Characteristic Notes & Conditions
Power Fail (PF) Open collector referenced to negative sense, transistor normally on when power is good (see fig. 5); power is considered good when
PFC bulk capacitor voltage is normal. PF: Provides ≥ 5 ms warning of loss of output from power failure.
Inhibit Uncommited isolated optocoupler diode, powered diode inhibits both V1 and fan supply (see fig. 6). During inhibit the standby
supply and current should be limited to 1 A for thermal reasons.
Output Good LED Indicator
Fan Speed Control
GSP500PSxx-EF Models
The fan speed is set to one of 4 states (high, mid, low or off) dependant on the internal power supply ambient temperature,
input voltage and output load at any given time.
Standby Supply 5V/2A Isolated supply present when AC applied.
Remote Sense Compensates for 0.5 V total voltage drop.
Current Share Optional, on ‘P’ version only. Connecting pins 5 or 6 on one unit to pins 5 or 6 on another like voltage unit will force the current to be
shared within 10% between the two outputs. Up to three units can share current. (see fig. 7)

Estimated Service Life vs Component Temperature
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.
--
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.
