20 Watt DC-DC Converters
The JTK20 series accommodates an ultra wide 4:1 range, and is available with either 9 – 36 or 18 – 75 VDC input voltage. With a 2:1 wide input range, the JCM20 series offers three input ranges of 9 – 18, 18 – 36 or 36 – 75 VDC inputs. Single output models provide +3.3, +5, +12 or +15 VDC, while the duals offer +/-5, +/-12 or +/-15 VDC. All outputs are fully regulated to within +/- 0.5% over all input and load conditions for the single output models and less than +/- 1.0% for the dual outputs. Single output models have an output trim that allows adjustment within +/- 10% of nominal output. Input to output and input/output to case isolation of 1,600 VDC is provided across the range.
Able to work in most environments, the JTK20 can operate at full load from -40 to +55 degrees C, and the JCM20 up to +65 degrees C, without the need for any additional heatsinking or forced airflow. With derating the JCM20 can operate up to +100 degrees C, and +105 degrees C for the JTK20.
Both series feature remote on/off control. This can be used to control the output rails or to sequence start-up procedures. All units also feature overvoltage, overload and short circuit protection.
