95% efficient 200 W convection cooled power supplies extends lifetime and temperature range

The CCB200 series of ultra efficient “green” 200 Watt single output AC-DC power supplies from XP Power is aimed at a broad range of medical and industrial applications. Suiting convection cooled applications that require a very high efficiency in an open frame design, the series has a typical efficiency of 94% and a maximum of 95%, with a flat efficiency curve across the entire operating load range above 20%.

Compared to typical 200 Watt supplies, the CCB200, when delivering full power, generates 50% less dissipated heat, resulting in significantly lower component temperatures and therefore an increased product lifetime. The high efficiency has enabled the convection-cooled units to be packaged in an industry standard 76.2 x 127.0 x 36.32 mm (3.0 x 5.0 x 1.43 inches), usually used for forced-cooled power supplies of this rating. No load power consumption is less than 0.5 W.

The series conforms to the ANSI/AAMI ES60601-1 medical 3rd edition safety standard and has approval for use in body floating (BF) applications where a patient applied part is used without the need for a further isolation stage. The CCB200 also complies with the internationally recognized UL/EN609501-1 safety standard for IT equipment.

Due to the high efficiency the CCB200 can deliver the full 200 Watt continuous output power over an extended temperature range from – 20 to +70 degrees C without any derating, and up to +85 degrees C with derating. The industry norm is typically + 50 degrees C before derating applies.

The technology employed in the CCB200 ensures the ultra high efficiency rating is achieved from 90 VAC input, unlike current products in the market that have lower efficiencies at low line and therefore have to specify derating. The full operating range of the CCB200 series is 80 – 300 VAC, with full power available from 90 – 264 VAC.

A total of 5 models are available providing the popular nominal outputs from + 12 to +48 VDC. A user trim function provides output voltage adjustment of -4 to + 5% of stated nominal in order to accommodate load losses.

Protection features and control signals include power fail signal, remote sense and remote on/off.
