The plastic case is silicone potted to provide a high level of resistance to shock and vibration, beneficial for
applications according to EN 50155, the standard for electronic equipment used on railway rolling stock.
Applications also include industrial and measurement equipment requiring battery back-up or a DC source.
One-fits-most converter with high insulation strength
The PYD20 series has three nominal single outputs, 5 V, 12 V and 15 V, adjustable over a -20 to +10 percent
range for non-standard voltages. Three dual fixed output models, ±12 V, ±15 V and ±24 V, are also available and
can be configured to operate as a single 24 V, 30 V and 48 V outputs. All models have overcurrent,
output-overvoltage and overtemperature protection. Remote on/off is standard.
The power modules have
efficiencies of up to 90 percent and can operate with a case temperature of between -40 °C to +105 °C with
derating at high temperatures.
The input to output isolation is 3,000 Vac and the PYD20 series has been certified to the IEC/UL/CSA/EN 62368-1
safety standards with the CE and UKCA marks for the Low Voltage and RoHS Directives. In combination with a
typical test setup, the PYD20 series has been tested to meet the EN 50155 railway standard.
