New series of medical and industrial DC-DC converters

TDK Corporation has introduced the PXD-M30 series of medical and industrial certified 30W board mount DC-DC converters. With 5,000VAC reinforced isolation between the input and output, these wide input range board mount converters are excellent for usage in medical, battery-powered and industrial equipment.

The series, like other 3W to 20W models in the PX-M range, can function from an input of 9VDC to 36VDC or 18VDC to 75VDC, and the range of output voltages covers 5, 12, 15, 24, ±5, ±12 and ±15VDC. Operation from 12V and 24V, or 24V and 48V nominal inputs decreases inventory carrying costs and betters part availability through distribution.

Packaged in industry-standard 2" x 1” size, the series measures 50.8mm x 25.4mm x 10.2mm. The operating ambient temperature is -40C to +105C, with de-rating above 40C for convection cooled environments, or above 73C with forced air cooling. Over-current, over-voltage and over-temperature protection is supplied as standard on all models. Positive or negative logic remote on-off is optional. Off-load input current consumption is just 10mA or less, enabling battery-powered products to remain functional longer in standby mode.

The series provides an input to output isolation of 5,000VAC (2 x MOPPs) and less than 2.5μA touch current. Safety certification includes IEC/EN 60601-1, ANSI/AAMI ES60601-1 and IEC/EN/UL/CSA 62368-1 with CE marking for the Low Voltage and RoHS Directives. The EMI standards EN55011-A, EN55032-A can be satisfied without the necessity for external components.
