261 to 500 watt medically-approved ac-dc power supplies

Emerson Network Power's NTS503-M medically-approved ac-dc power supply is available in a fan-cooled version capable of delivering up to 500 watts at ambient operating temperatures up to 50 ˚C. The power supply is digitally controlled – it features a PMBus™-compliant I2C interface – and generates a tightly regulated 12 V output that can be used to directly power boards fitted with multiple non-isolated dc-dc converters. It also produces an auxiliary 'always-on' regulated 5 V @ 2A output for applications that require standby operation, as well as a 12 V output for powering fans.
