XP Power has launched a convection cooled 600W AC-DC medical power supply series that delivers full load power under a wide range of conditions without additional cooling.

The convection coling means the UCH600 medical power supply series is suited to applications where no forced air is available, or fan noise or the ingress of dirt is undesirable. This includes medical devices, as well as those requiring BF patient protection, that need to operate silently. ITE or industrial electronics applications in environments where dirt ingress would be exacerbated by forced air cooling or where audible noise and fan reliability issues also mean forced air cooling is impractical.

The medical power supply series meets EN55011/32 Class B for both conducted and radiated emissions with significant margin, making them a low risk for integration and system approvals for the end-use equipment. Class C harmonics compliance makes the ensure the UCH600 ideal for lighting and display applications. It measures 203 x 127 x 40mm (8.0” x 5.0” x 1.57”) giving a power density of 9.5W/in3. The U-channel construction and low profile allow for flexible installation into a wide range of applications.

The efficiency up to 95% per cent minimises waste heat and ensures that the power supplies can deliver the full rated power at ambient temperatures up to +50ºC, even at low line input. At 70ºC, 300W is available without any form of forced air cooling being required. For equipment designs where some forced air cooling is employed, a 12V/0.6A auxiliary fan supply is available.

The UCH600 series carries worldwide safety approvals for ITE/industrial and healthcare applications including IEC60950-1, IEC/EN/UL62368-1 and IEC/EN60601-1 3rd Edition. It is available from Digi-Key, Farnell, Mouser, RS Components, approved regional distributors, or direct from XP Power with a 3-year warranty.
