The GSP750 offers a full 750 W of output power in a very small mechanical footprint while providing peak power to up to 900 W, a 5 V standby output with 3 A current capability and an input standby power draw of <1.0 W when the inhibit is activated.

Approved for both IT/Industrial and medical applications the series has output versions from 12 V to 48 V. Cooling fans are intelligently controlled to reduce accoustic noise in the system and the GSP750 provides up to 50 W without forced cooling, allowing the fans to be switched off, providing silent running during periods of lower system loading or system standby conditions.

Signals & Controls

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	The fan speed is set to one of 4 states (high, mid, low or off) dependant on the internal power supply ambiennt temperature, input voltage and output load at anhy given time.
Standby supply	5V/ 3A Isolated supply present when AC applied.
Remote sense	Compenstes for 0.5 V total voltage drop.
Current share	Connedting 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 gig. 7)
