Power supplies are 20 percent smaller, 91 percent more efficient
ETA-USA has introduced the new ESS Family of power supplies with UL 60950, UL 508 listings and a full 5-year warrantee. The ESS family is 20 percent smaller with efficiencies to 91 percent. The ESS family will accept input voltages of 85V to 264Vac, 47 to 440Hz, with up to .99 power factor, or 110V to 350Vdc. Standard DC output voltages range from 3.3V to 48V, and deliver full load to 50oC with convection cooling. Important features include Over Current Protection (OCP), Over Voltage Protection (OVP), and remote sensing for precision voltage regulation at point of use (in supplies of 100W and above.) Options include Remote Control (for 50W and above), DIN Rail mounting and use of Molex “-J” connectors.
