400W medical PSU gets seven output options from 12V to 48V

The new options 15, 19, 28, 36 or 48V.

400W is available with forced cooling (30 minutes, 40°C ambient, 230Vac in, 50% duty). “The duration period of that peak is considerably longer than most products on the market,” according to the company “This feature makes the CUS400M ideal for medical applications with a relatively low quiescent power consumption and occasional peak demand, including hospital beds, dental chairs and incubators.”

250W is available when convection cooled, with peaks up to 400W.

Input range is 85 to 264Vac and off-load consumption is <1.3W when the output is inhibited.

As options, units can be fitted with a 5V 2A or 12V 1A stand-by voltage, remote on-off, remote sense, AC fail and an output good signal.

Several different mechanical arrangements are available, including open frame versions in the industry-standard 3” x 5” footprint. Other mechanical configurations include a metal baseplate, U-channel, enclosed or integral top-mounted fan.

Cooling is assisted via conduction through the base into the equipment chassis or a cold plate – there is a option for a thermally conductive electrically insulated plastic base .

Medical and industrial safety certifications include IEC/EN/ES 60601‑1 and IEC/EN/UL 62368‑1 with CE marking for the Low Voltage, EMC and RoHS Directives. The units also comply with EN 55011‑B and EN 55032‑B conducted and radiated emissions (Class I and II), and meet the EN 61000‑3‑2 harmonics, IEC 60601‑1‑2 Edition 4 and IEC 61000‑4 immunity standards.

Input to output isolation is 4,000Vac (2 x MoPP), input to ground isolation is 1,500Vac (1 x MoPP) and the output to ground isolation is 1,500Vac (1 x MoPP) for suitability in B and BF rated medical equipment.

Leakage current is a maximum of 250µA, and the touch current is less than 100µA. The operating, transportation and storage altitude is up to 5,000m, which supports global use and sales of end-equipment.
