The BEO-3000M AC/DC switching power supply series from Bicker Elektronik, Donauwoerth/Germany, was developed for space-saving installation in medical devices and medical computer systems. The 3x5" open frame power supplies are available with precisely regulated DC single output voltages of 12V, 24V, 36V or 48V, which can be fine tuned in the range of ±5%. In addition, a 5V standby and a 12V fan output is available.

The medical power supplies for reliable 24/7 continuous operation provide an output power of 250W fanless or 300W with 10CFM airflow. With a high efficiency of up to 94%, a standby power consumption of less than 0.3W and an operating temperature range of -40°C to +70°C, the BEO-3000M series is also convincing in closed systems.

For international use, the medical switching power supplies have a wide-range input (90 to 264VAC at 47 to 63Hz) with active PFC power factor correction.

With a high isolation voltage of 6516VDC between input and output, the BEO-3000M series complies with the medical safety standard 2xMOPP (Means Of Patient Protection) and has international medical safety approvals: IEC60601-1:2005+A1:2012 (Edition 3.1), EN60601-1:2006+A1:2013 (Edition 3.1), ANSI/AAMI ES60601-1:2005 (3rd Edition).

The BEO-3000M series comes standard with short circuit and overtemperature protection with auto-recovery and over-voltage protection with shutdown, as well as a remote sense function to compensate voltage drops on the output lines to the load.

No base load is required at the outputs, so latest-generation mainboards (Skylake / Kaby Lake / Coffee Lake / Gemini Lake) with their special power-saving modes can be safely supplied. For operation of medical computer systems, the BEO-3000M power supplies also have ATX-compatible PSON and PG / PowerGood signal ports.

In addition to the long-term availability of at least 5 years Bicker Elektronik grants a warranty of 3 years on the power supply series BEO-3000M. In addition, the power supply specialist offers suitable accessories such as the two AC input cables X1-054 (2-pin) and CB-105-3-600 (3-pin), the IEC connector filter PSZ-1019-B1 incl. cable and ferrite as well product specific connection cable set PSZ-1035.
