400W medical power supply has 'smallest footprint'

SynQor brings to the design of its ACuQor series of AC/DC products the same level of technical innovation that has made it a leader in the DC/DC marketplace, achieving an efficiency level of 91 per cent. Single outputs of 48, 36 or 24V are available to facilitate the use of distributed power architectures and battery backup, and to directly drive components such as fans, motors, pumps, lamps and actuators.

The AcuQor family operates over a universal input range of 85-264Vrms and 47-63Hz, making it suitable for worldwide deployment. Full output power is available up to 50degC with natural convection, derating linearly to 300W at 70degC. A transient power rating of 500W is possible for up to 5s in the open-frame version, and even longer in a proprietary encased version. Active power factor correction is incorporated to a level >0.98, enabling compliance with IEC/EN 61000-3-2. Both AC lines are internally fused.

Various ACuQor models are available, including versions designed for both BF (direct patient contact) and CF (direct cardiac contact) applications in accordance with UL/EN 60601-1. Input earth leakage current and type CF patient leakage current are well below the requirements of the standard at

A host of additional control and signalling inputs and outputs are offered, including a 5V always-on standby power output, a DC power good signal, AC power good signal, remote enable input, and a fan status output/fan enable input function. Over-current, over-voltage and-over temperature protection with auto-recovery are also built into the unit. The operating temperature range is 0 to +70degC.

Sample and production quantities are available immediately with a stock to 10-12 week lead-time. The 400W ACuQor power supplies are priced at $400 in 1000-piece quantities.
