The latest addition to Schroff’s ecopower range of ac/dc switch-mode regulators is a compact 200W plug-in unit that takes up just half the width of a conventional power supply of this performance level and yet is able to achieve an efficiency of 90% using only convection cooling.
Particularly aimed at datacom and telecom applications, the new SEC148-200 power supply provides a main output of 48V, together with a battery-charging output of 56V. It is designed for mounting in a 3U-high subrack and can be used in hot-swap capable systems. Since it operates without fan cooling, it achieves a high MTBF and is therefore ideal for high-availability n+1 redundant applications.
When used with active power factor correction according to EN 61000-3-2, the SEC148-200 can achieve efficiency levels as high as 98%. The PSU features a wide input voltage range of 90 to 256Vac and can be specified with an optional integrated microcontroller to provide monitoring, control and alarm functionality.
