The ACC750 Series of AC-DC power supplies provides a steady 750 W of regulated DC power through 180-305 VAC and 600 W through 85-137 VAC input voltage ranges in a single output of 24 or 48 VDC. The natural convection cooling operation (without fan), is particularly suitable for environments sensitive to acoustical noise. The ACC750 Series comes in two U-shaped 1.6 high packages, with and without a protective cover, offering 12 and 5 VSB standby outputs and a full set of protection features. The ACC750 Series supports digital power management over the Power Management Bus communications protocol. Multiple units may be connected in parallel for redundancy and / or higher power, enabled with the internal OR-ing and current sharing functions. The ACC750 Series complies with the latest international safety standards and displays the CE-Mark for the European Low Voltage Directive (LVD). Universal input voltage range (85 305 VAC) Input inrush current limiting 750 W rated power (900 W peak for <10 s) High efficiency up to 94% Single 24 VDC / 48 VDC output voltage available Active PFC, EN61000-3-2 compliant (Class C, >25% load) Low earth / touch leakage current Natural convection cooling Over temperature, OV, OC and SC protections +12 V / 0.3 A +5 V / 0.72 A Stand by outputs Built-in current sharing and OR-ing for parallel operation and N+1 redundancy Power good and remote sense signals Remote On / Off signal Power Management Bus communication protocol supported ITE safety approval to IEC 62368-1 LED lighting approval to UL 8750 Video Wall Display, Entertainment Lighting LED Lighting Engine Industrial Control Systems Industrial Laser Applications 2 ACC750 Series INPUT NOM.
