Lambda’s new PXF40-xxW wide-range input converters are offered with a choice of two input voltage ranges: 9 to 36V and 18 to 75V. Single output types are available with output voltages from 3.3V to 15V, while dual-output versions are available in ±12V and ±15V models.
Like all products in the PXF family, the new converters offer 40W output capacity in the industry-standard 2 x 2 footprint that is typically associated with 30W devices. They offer isolation rated at 1,600V between input and output, with a maximum isolation capacitance of 1,000pF.
To minimise radiated noise, PXF converters include six-sided shielding. They fully meet the requirements of EN55022 Level A for radiated emissions and they are also compliant with the relevant sections of EN61000-4 for immunity.
Reliable operation of the converters, even in adverse conditions is ensured by the over-current and short-circuit protection features that come as standard and by the generous input surge voltage ratings of the devices. Over-voltage protection, which takes the form of a zener clamp is also featured on all outputs.
With an operating temperature range of -40 to +85ºC, a relative humidity range of 5 to 95% and a typical MTBF in excess of 1.3 million hours, PXF DC/DC converters from Lambda, in both standard and wide input range versions, are a dependable, convenient and cost-effective choice for even the most demanding of applications.
