INSTRUCTIONS

DC POWER SUPPLY

PS-300

PRECAUTIONS

• RWARNING! NEVER apply AC voltage that exceeds the

specified voltage to the PS-300’s AC power cable. Exces­sive voltage could cause a fire or ruin the power supply.

• RWARNING! Immediately turn the power supply OFF

and remove the AC power cable if it emits an abnormal
odor, sound or smoke. Contact your Icom dealer or dis­tributor for advice.

• RCAUTION! NEVER let metal, wire or other objects

touch any internal parts through the slits of the case or
terminals on the rear panel of the power supply. This may
result in an electric shock.

•

RCAUTION! NEVER connect the power supply to a DC
power source using reverse polarity. This will damage the
power supply.

• RCAUTION! NEVER open the top cover. There are no

user adjustment parts. Opening the case may expose you
to electric shock and incorrect reassembly may cause a
fire hazard.

Thank you for purchasing the PS-300 dc power supply.

Please read these instructions thoroughly before operat­ing the PS-300.

• RCAUTION! NEVER put the power supply in any unsta-

ble place (such as on a slanted surface or vibrating area).
This may cause injury to you and/or damage to the power
supply.

• RCAUTION! The socket-outlet must be near the DC

power supply and must be easily accessible.

• RUSE INDOORS ONLY! NEVER expose the power sup-

ply to rain, snow or any liquids.

• DO NOT use or place the power supply in areas with tem-
peratures below 0°C or above +40°C.

• DO NOT use chemical agents such as benzine or alcohol
when cleaning, as they can damage the power supply’s
surfaces.

• DO NOT place the power supply against walls or put any-
thing behind the power supply. This will obstruct heat dis­sipation.

• KEEP the power supply out of the reach of children.

• USE an AC outlet that can supply more than 840 VA ca-
pacity. AVOID the use of a multi-plug adaptor.

CONNECTION AND OPERATION

q Connect the AC power cable of the PS-300 to an AC out-

let.

w Turn the PS-300 ON, then adjust the suitable output volt-

age.

• “ I ” : ON (Power indicator lights green)

• “O” : OFF (Power indicator goes off)

e Turn the PS-300 OFF, and make sure the equipment's

power is also OFF.

r Connect the DC power cable to the PS-300 and the

equipment's DC power input.

t Turn the PS-300 ON.
y Turn the equipment ON.
u To turn OFF the system, turn the equipment power OFF,

then the PS-300 in sequence.

CURRENT CAPACITY

Current capacities of the PS-300 depend on their output
voltage as per the graph at right. (The graph shows typical
values for reference.)

OVERLOAD AND SHORT CIRCUIT PROTECTOR

The PS-300 has overload and short circuit protection circuits.
When the PS-300 is under the condition of overload or the +
and _ lines are shorted, the PS-300 limits the output current
and the overload indicator lights red. In such a case, turn OFF
the PS-300, remove the source of the problem, wait several
seconds, then turn it ON again.
