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 VDC (18 VDC to 36 VDC) or 48 VDC (36 VDC to 75 VDC) nominal input, and outputs cater for the popular voltages of 3.3, 5, 12, or 15 VDC. 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 VDC.
The units meet EN55022 level A conducted and radiated emissions with no external components necessary.
