PXD-M30 DC/DC converters have wide input ranges

Medical and industrial DC/DC converters from TDK-Lambda make up the PXD-M30 series. The 30W board-mount DC/DC converters have 5kVac reinforced isolation and wide 4:1 input ranges.

They also have 5,000V AC reinforced isolation between the input and output for 2 x MOPPs and less than 2.5μA touch current, making them suitable for medical, battery powered and industrial equipment.

The PXD-M30 series, like other 3.0 to 20W models in TDK’s PX-M range, can operate from an input of 9.0 to 36V DC or 18 to 75V DC, and the range of output voltages covers 5.0, 12, 15, 24, ±5.0, ±12 and ±15V DC. Operation from 12V and 24V, or 24V and 48V nominal inputs reduces inventory carrying costs, advises TDK, and ensures parts are available through distribution channels.

Packaged in an industry standard form factor, the PXD-M30 measures 50.8 x 25.4 x 10.2mm (2.0 x 1.0 x 0.4 inches). The operating ambient temperature is -40 to +105 degrees C, with de-rating above 40 degrees C for convection cooled environments, or above 73 degrees C with forced air cooling. Over-current, over-voltage and over-temperature protection is standard on all models. Positive or negative logic remote on-off is optional. The off-load input current consumption is 10mA or less, allowing battery powered products to remain functional longer in standby mode.

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 met without the need for external components, advises TDK.

TDK was established in 1935 to commercialise ferrite, a key material in electronic and magnetic products. TDK’s portfolio features passive components such as ceramic, aluminium electrolytic and film capacitors, as well as magnetics, high-frequency, and piezo and protection devices. The product spectrum also includes sensors and sensor systems such as temperature and pressure, magnetic, and MEMS sensors. Products are marketed under the product brands TDK, EPCOS, InvenSense, Micronas, Tronics and TDK-Lambda. TDK focuses on demanding markets in automotive, industrial and consumer electronics, and information and communication technology and has a network of design and manufacturing locations and sales offices in Asia, Europe, and in North and South America.
