Keep this manual in a safe place for quick reference at all times.
This manual contains important safety and operation instructions for correct use of the DC Converter.
Read through the manual and pay special attention to the markings and labels of this unit and
equipment to be connected.
Pay special attention to these two types of notices used in this manual
WARNING: Failure to observe this warning may cause injury to persons and damage
to the DC converter or connected equipment.
CAUTION: Failure to observe this warning may result in damage to equipment and improper
functioning of the DC Converter.

Caution
1. Do not use the unit for equipment which requires current input higher than the maximum
specified value.
2. Do not use the unit for lamps or motorized equipment that requires high starting surge current.
3. Before replacing the internal input fuse, find out and clear the cause first. Only replace with fuse
of the same type and rating.
4. Do not connect input voltage outside the specified input voltage range of 18 to 38VDC.
5. Never turn ON the unit when the load is set at full load even if the load current is within the
range.
6. Always place the unit in well ventilated area as high heat is generated.
7. Never install the unit near heat sensitive material as the casing of unit can get as high as 60°C
(140°F).
8. Never apply a voltage source higher than 13.8V without a proper diode to the output, otherwise
unit may be damaged.
9. Although the unit has very low standby current, it is advisable to disconnect the DC input if the
unit is not to be used.
Introduction
PDC series DC converters offer regulated 13.8V DC power from 20-30VDC sources. It implements
switching mode technology to generate less heat yet higher efficiency. Its advanced design and
sturdy construction assures continue stability and reliability.
Features
1. Overload Protection: When the output current reaches the maximum limit, the overload circuitry
is activated and the output voltage and current are reduced to protect the unit.
2. Over Voltage Protection: When the output voltage reaches the maximum limit, the over voltage
protection is activated and the output voltage shuts down. For PDC-6205, internal input fuse will
blow and all indicators will turn off. For PDC-6207 & 6212, protection is maintained even though
output load is removed. The unit can be reset by disconnecting input for about 5-10 seconds.
3. High RFI Stability: The unit is designed with high protection circuitry against Radio Frequency
interference.
4. Operation and Fault status LED indicators.
5. Versatile clip-on mounting bracket for quick installation.

Installation and Operation
1. Mount the clip-on mounting bracket with included machine screws and clip the unit onto the
mounting bracket. Make sure it is pushed all the way in to the bracket.
Note: It is recommended to mount the unit horizontally.
2. Crimp the input and output cables with the included quick-connect crimp connectors. Use
different colored cables for clear identification of the inputs, outputs & polarities.
Note: Recommended wire gauge sizes are at least 18 AWG for PDC-6205, 16 AWG for
PDC-6207 and 14 AWG for PDC-6212.
3. Connect the input cable to input terminals watching the polarity carefully. The green LED
should light up.
4. Turn OFF the output equipment and then make the connection to the output terminals
making sure of the correct polarity.
5. Turn ON the equipment to be powered.
Trouble Shooting
1. None of the indicator LED is ON.
Check input source for open circuit and loss of earth. Remove the load to check if green
LED is ON. If green LED is still not ON, check if input voltage level is within the range,
check if polarity is correct, and check if battery level is normal. Unit will return to working
condition once the fault has been corrected or removed.
2. Red LED is ON.
Remove the load to check if green LED is ON. If green LED is ON, the unit may be in
overload or short circuit protection. Check the power requirement and the condition of the
connected equipment which triggers the red LED. Loads like high power halogen/quartz
lamps, motorized equipment that requires high surge starting current (which is many times
over its rated current) will trigger the protection of the unit. They are not suitable for use with
the unit.
