60 Watt 

Single Output, Isolated, 12:1 Extremely Wide Input Range

OFQC60 DC-DC Converters

Our OFQC60 Series of isolated 60-W single output DC-DC converters is available in two extremely wide 12:1 input ranges of 9-75V and 14-160V DC, with each offering output voltages of 5, 12, 15, 24, 28, 48 or 53V DC. The units come in a plastic case with aluminum baseplate and have an industry-standard quarter-brick footprint. Featuring efficiencies as high as 92 percent, up to 3000V AC isolation voltage, and remote ON/OFF, these DC-DC converters meet EN 50155 standards for railway applications. Built-in safeguards include over temperature, overcurrent, overvoltage, undervoltage and short circuit protections. The operating baseplate temperature range is -40°C to +105°C, and heat sink options are available. OFQC60 DC-DC converters comply to RoHS and REACH, with CE Mark pending.
