MGFS Single Output Isolated DC-DC Converters Cosel MGFS Single Output DC-DC Converters are PCB mount type converters offering single and adjustable output voltages by an external variable resistor (+10%/-5%). The MGFS converters feature a -40°C to +80°C temperature range, 9VDC to 76VDC input voltage, and 100mA to 18A output current range. These DC-DC converters feature built-in overvoltage and overcurrent protection.
