GSP750 Series AC-DC Power Supplies 750 Watts • 900 W Peak Power Rating for 100 ms • Universal 80 - 264 VAC Input • IT & Medical Safety Approvals • 1.0 W Standby Power • -40° C to +70° C Operation • Remote On/Off • 5 V/3 A Standby Output • 3 Year Warranty The GSP750 has been designed to offer a full 750 W of output power in a very small mechanical footprint, whilst still providing peak power to 900 W, a 5 V standby output with 3 A of current capability and an input standby power draw of <1.0 W when the inhibit is activated. Dimensions: GSP750: 10.0 x 4.0 x 1.65” (254.0 x 101.6 x 41.91 mm) Approved for both IT and medical applications the series has output versions from 12 V to 48 V. The cooling fans are intelligently controlled to provide the most optimised accoustic noise in the system and further more the GSP750 can provide up to 50 W without forced cooling, allowing their fans to be switched off during periods of lower system loading.

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 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/3A Isolated supply present when AC applied. Remote Sense Compensates for 0.5 V total voltage drop. Current Share 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.
