IcePower 750S 69V 750 Watt Power Supply Module
The IcePower 750S is a universal mains power supply designed for demanding professional audio and high-performance audio products. Its active power factor correction helps make efficient use of available AC power, while the universal 100 to 240 V AC input range removes the need for region-specific variants.
With ±69 V VD and VS output rails, the 750S is built to supply compatible ICEpower amplifier modules, including up to two ICEpower400A2 or ICEpowerSC400A2 modules for systems with up to four channels of music. It delivers 750 W rated combined output power at 230 V AC and 120 V AC, 650 W at 100 V AC, and up to 1200 W peak power at 20 Hz on 230 V AC.
The integrated 22 W auxiliary converter provides useful rails for front-end electronics, control circuits, analog stages, and active cooling support. Available auxiliary outputs include 6 V DVDD and DVDD_STBY, ±14 V analog auxiliary rails, 10.5 V Vdrive for hanger modules, and an 11.5 V VAUX_MAIN output suitable for powering 12 V fans in actively cooled designs.
Designed for fast integration into stereo HiFi amplifiers, multichannel amplifiers, high-end studio monitors, and reference-grade active speakers, the 750S includes overload, short-circuit, overvoltage, thermal, mains-present, and power-good monitoring functions. The module measures 207 x 80 x 41 mm, weighs 580 g, supports up to 50 °C operating ambient temperature with active cooling, and is safety listed to UL 62368-1 with EMC evaluation for CE and FCC-oriented designs.
