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 percent 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.
The 6HP-wide PSU 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 percent. The PSU features a wide input voltage range of 90 to 256V AC and can be specified with an optional integrated microcontroller to provide monitoring, control and alarm functionality.
All ecopower SEC148-200 power supplies undergo fully automatic testing, including AOI and burn-in for a minimum of 8 hours, to ensure the high quality of the product.
