Bel Power Solutions ACC/MCC750 series 750W AC/DC power supplies

Bel Power Solutions announced the ACC750 (industrial) and MCC750 (medical) series of convection cooled power supplies which are available in a couple of single output voltages. The natural convection cooling operation (without a fan) is particularly suitable for environments sensitive to acoustical noise.

The ACC/MCC750 series provides up to 750W (900W peak for <10s) of regulated output power through a wide input voltage range of 85VAC – 305VAC in a single output of 24VDC or 48VDC. The ACC750 series comes in two U-shaped 1.6" high packages, with and without a protective cover, offering 12 and 5VSB standby outputs and a full set of protection features. These power supplies are ideal for video wall display and entertainment lighting, LED lighting engines, industrial control systems and industrial laser applications.

The MCC750 series is designed and approved to comply to the latest medical standards (EN/IEC 60601-1) for medical equipment requiring 2x MoPP protection grade and displays the CE-Mark for the European Low Voltage Directive (LVD). These medical power supplies are ideal for laboratory and analysis equipment, x-ray and CT scanners, dental equipment, as well as medical devices and applications.

The ACC750/MCC750 series supports digital power management over the Power Management Bus communications protocol. Multiple units may be connected in parallel for N+1 redundancy and/or higher power, enabled with the internal OR-ing and current sharing functions.
