High Efficiency and Rapid Customization open-frame Power Supplies

It features two essential characteristics of the compact built-in components: very high efficiency (high efficiency and low standby losses) meets an easy-to-adapt open design for fast customer-specific modifications. The first lines of the new product series include output voltages of 5 – 48 VDC for power classes of 18 W, 30 W and 175 W.
As to open-frame PS dimensions, standard measures of 3″x2″; 4″x2″ and 5″x3″ for the different power classes have become well-established, and are also met by the HERC series. The very compact design includes, in addition to length and width, the height, which is only 1″- 1.3″ for the HERC line.
With up to 94 % efficiency, the power supplies belong to the top tier. FRIWO also sets new standards for idle power consumption: the DOE VI requirements for external power supplies are exceeded, which is quite unusual for open-frame power supplies. The units can be operated in an ambient temperature range from – 25° C to 70° C. A dual power concept allows the unit to be used both as a convection-cooled and a fan-cooled power supply.
The HERC line meets the medical requirements of IEC60601-1
