SAFETY PRECAUTIONS

GENERAL
Please read through this operating instruction care-
1)
fully and follow the instruction to prevent from abuse
or misuse. This instruction must be kept to refer
anytime in need.
The DD-105 and the DD107 are specially designed
2)
DC-DC converter to use DC13.8V operated radio
equipment sourcing from DC24V outlet providing 5A
continuous operation (DD105) or 7A continuous
operation (DD107).
Note : Continuous operation to be 8(eight) hours
under 24V input at 25°C.
NO RESPONSIBILITY is extended to other than
above applications and/or use.
Over Voltage Protection
3)
When DC16V ±0.5V is appeared at the output
terminal, the input voltage will be automatically shut
down to protect the unit.
Over Current Protection
4)
When the output current comes over the limitation,
the output voltage and current will be automatically
reduced to protect the unit.
■
CAUTION
DO NOT use for equipments require higher current
1)
input than the designed value otherwise it may
damage the unit.
DO NOT use this unit for charging battery.
2)
DO NOT use for lamps or motorized equipment
3)
which require high current input at starting as it may
damage the unit.
DO NOT replace the fuse before ceasing problems
4)
and the assigned value of fuse must be taken in
place.
DO NOT feed input voltage other than DC20V –
5)
DC30V as it may damage the unit. The input
voltages specified here are for the purpose of
operationble application only.
DO NOT start unit while the radio is being
6)
transmitted as it may damage the unit.
NEVER touch the heatsink panel during the unit is
7)
powered. Touching it may burn your hands or part of
your body by high temperature.
NO DC24V output can come out from the input
8)
when feeding DC12V to the output.
BE SURE wiring connections otherwise it may
9)
damage the unit. While cable is for INPUT(+) and
Black cable is for INPUT(-). Red cable is for
OUTPUT(+) and Black cable is for OUTPUT(-).
