USER’S MANUAL
INTRODUCTION
FUM-1224-40FDC is high quality 24V~13.8V DC-DC Power Converter primarily designed for 13.8VDC powering of
automotive and marine electronic equipment. It is implemented by using Switching Mode Power Suplí technology to
make it generate less heat and hence higher efficiency. Advanced design, quality production control and sturdy
construction assure continue stability and reliability.
FEATURES
1. Overload Protection: When the output current is being over the limitation, the overload circuitry is activated and the
output voltage and current are reduced to protect the unit.
2. Over Voltaje Protection: When the output Terminal appears over the voltaje output limit, the over voltaje protection is
activated and the output voltaje is shut down to protect the unit and your equipment.
3. High RFI Stability: The unit is designed for high protection circuitry against RFI (Radio Frequency Interference)
provides a stable operation without affected by RFI.
FRONT PANEL
1. POWER SWITCH: Switch ON/OFF the unit.
2. POWER INDICATOR: Lights up when the unit is activated.
3. SCREW-ON OUTPUT TERMINAL: Full load output terminal.
4. 2–WAY TERMINAL BLOCK: Max. 15A Output Terminal.
Note: The total output current of all terminals must not exceed the output current as listed on the specifications next
page.
CAUTION
1. DO NOT use the unit for the equipment requires current input that higher than the designed value otherwise it may
damage the unit.
2. DO NOT use the unit for charging battery.
3. DO NOT use the unit for lamps or motorizad equipment that require high current input at starting as it may damage
the unit.
4. When the fuse is broken, DO NOT replace the fuse befote ceasing the problem. The value of the fuse taken in place
must match the assigned value.
