Thank you for purchasing the PS-250 DC-DC POWER
SUPPLY.
Please read these instructions and transceiver’s
instruction manual carefully before installation and
operation.
PRECAUTIONS
• RNEVER apply AC voltage to the DC input terminals
on the rear panel. This could cause a fire or damage the
power supply.
• RNEVER apply more than 32 V DC to the DC input ter-
minal on the rear panel. This could cause a fire or damage the power supply.
• RNEVER connect the power supply to a DC power
source using reverse polarity. This will damage the power
supply.
• RNEVER let metal, wire or other objects touch any in-
ternal part or terminals on the rear panel of the power
supply. This may result in an electric shock.
• RNEV ER open the bottom cover. There are no user
adjustment points. Opening the case may expose you to
electric shock and incorrect reassembly may cause a fire
hazard.
• RNEVER expose the power supply to rain, snow or any
liquids.
• DO NOT use or place the power supply in areas with
temperatures below –15°C or above +55°C.
• DO NOT use chemical agents such as benzine or alcohol when cleaning, as they can damage the power supply’s surfaces.
• DO N OT place the power supply against walls or put
anything to behind the power supply. This will obstruct
heat dissipation.
• BE CAREFUL! The surface will become hot when operating the power supply continuously for long periods.
• KEEP the power supply out of the reach of children.
IMPORTANT!
The connected transceiver may receive switching noise
from this power supply depending on the antenna used
and/or installing conditions, etc.
