The compact convection-cooled JCK60 has a power density of 37.5 W/in3 and no need for forced-air cooling, additional heat sink, or baseplate cooling.

XP Power Technologies has launched the JCK60 series of highly-efficient metal cased 60-W DC-DC converters for a broad range of telecommunications, networking, and industrial applications. Measuring 50.8 x 50.8 x 10.16 mm (2 x 2 x 0.4 in), the compact convection-cooled JCK60 has a power density of 37.5 W/in3 and no need for forced-air cooling, additional heat sink, or baseplate cooling. The single output JCK60 series accommodates a 2:1 input-voltage range and includes under-voltage lockout. Models are available with either a 24 VDC nominal (18 to 36 VDC) or 48 VDC nominal (36 - 75 VDC) input, while outputs cater to the popular voltages of 3.3, 5, 12 or 15 VDC. An output trim function allows 10% adjustment of the output voltage and remote sense compensates for interconnect voltage drops. The converter operates across a temperature range of -40 to +85 °C . Full output power is available up to +40 °C without derating. A remote on-off control input provides an external control of the output and can be used for start-up sequencing. Over-voltage, overload, and continuous short-circuit protection features are standard across the range. All models have an input to output and input and output to case isolation of 1,600 VDC. The units meet EN55022 level A conducted and radiated emissions with no external components necessary. The JCK60 is available from Farnell, element14, approved regional distributors, or direct from XP Power and comes with 3 year warranty. XPower Technologies
