XP Power announces the JCK60 series of highly-efficient, metal-cased 60 W DC-DC converters aimed at a broad range of telecommunications, networking, and industrial applications. Measuring only 50.8 x 50.8 x 10.16 mm (2 x 2 x 0.4 inches), the compact convection-cooled JCK60 has a high-power density of 37.5 W per cubic inch and has no need for any forced air cooling, additional heat-sinking, or baseplate cooling.

The single-output JCK60 series accommodates a 2:1 input voltage range and includes undervoltage lockout. Models are available with either a 24 V_DC (18 V_DC to 36 V_DC) or 48 V_DC (36 V_DC to 75 V_DC) nominal input, and outputs cater for the popular voltages of 3.3, 5, 12, or 15 V_DC. An output trim function allows the adjustment of output voltage of ±10% of nominal, and remote sense compensates for drops in voltage at the load.

The converter is capable of operating in most environments and across a wide range of temperatures from -40°C to 85°C. Full output power is available up to 40°C without derating.

A remote on/off input provides an external control of the output and can be used to sequence start-up procedures. Overvoltage, overload, and continuous short-circuit protection features are standard across the range. All models have an input-to-output and input/output to case isolation of 1,600 V_DC.

The units meet EN55022 level A conducted and radiated emissions with no external components necessary.
