ESCRIPTION

The EF Series of switching power supplies utilizes advanced component and circuit technologies to deliver the industry’s smallest 350-400 Watt switcher. Built to meet 1U height considerations, the U-Frame package measures only 6.80 x 3.86 x 1.40”. All models offer universal AC input (85-265 VAC) with active power factor correction (PFC), optional 48 VDC input, flexible output configurations and compliance to worldwide safety and EMC standards. Features include:• 350W & 400W compact high-density models• Active load current share • Universal AC input with PFC • Ruggedized U-Channel construction • 48V & 24V DC Input models available • RoHS compliant • Includes OR-ing diode for N+1 parallel operation • International regulatory approvals
