High Voltage DC-DC Converters
PR45-24S300 DC-DC converters are rated at 300 Vdc output at 15-watt output in a 1.98” x 1.58” x 1.25” package. They provide 85% efficiency at full load and operation down to no load, remote ON/OFF control, fixed switching frequency of 350 kHz (typ.) and output trim to 50 V dc. The 100 percent burn-in tested units offer built-in over current and short circuit protection and can operate over a wide temperature range of -40°C to +70°C. The series is designed to meet UL 60950-1, EN60950-1 and IEC 60950-1.
