INSTRUCTION MANUAL
iPW1
HF/50 MHz ALL BAND
1 kW LINEAR AMPLIFIER
RW ARNING HIGH VOLTAGE! NEVER attach
an antenna or internal antenna connector during transmission. This may result in an electrical shock or burn.
RWARNING! NEVER carry the linear amplifier by
yourself. At least two persons must carry the linear
amplifier since it weights approx. 25 kg (55 lb).
RWARNING! NEVER apply AC voltage until the
linear amplifier is grounded. Touching the linear amplifier may result in an electrical shock.
RNEVER apply AC voltage that exceeds the sug-
gested voltage. This could cause a fire or ruin the
IC-PW1.
RNEVER use an extension cord with the AC power
cable. Extension cords may cause fire or electrical
shock.
RNEVER let metal, wire or other objects touch any
internal par t or connectors on the panel of the linear
amplifier. This will cause electric shock.
RNEVER expose the linear amplifier or remote con-
troller to rain, snow or any liquids.
NEVER allow children to play with the linear ampli-
fier or remote controller.
DO NOT operate the IC-PW1 before adjusting the
[ALC adj1] and [ALC adj2] pots properly on the rear
panel of the linear amplifier.
AVOID using or placing the linear amplifier or remote
controller in areas with temperatures below –10°C
(+14°F) or above +40°C (+104°F).
AVOID placing the linear amplifier or remote controller
in excessively dusty environments or in direct sunlight.
AVOID placing the linear amplifier against walls or
putting anything on top of the linear amplifier. This will
obstruct heat dissipation.
BE CAREFUL! The linear amplifier will become hot
when operating if continuously for long periods.
BE CAREFUL! Set the transceiver’ s (exciter’ s) RF output power to less than 100 W, otherwise, the IC-PW1
will be damaged.
During maritime mobile operation, keep the linear amplifier, remote controller and microphone as far away
as possible from the magnetic navigation compass to
prevent erroneous indications.
The IC-PW1 cannot be used with the AH-2 HF AUTO-
MATIC ANTENNA TUNER.
For U.S.A. only
CAUTION:Changes or modifications to this device,
not expressly approved by Icom Inc., could void your
authority to operate this device under FCC regulations.
READ THIS INSTRUCTION MANUAL
CAREFULLY before attempting to operate the lin-
ear amplifier.
SAVE THIS INSTRUCTION MANUAL. This in-
struction manual contains important safety and operating instructions for the IC-PW1.

PANEL DESCRIPTION
q POWER SWITCH [PO WER](p. 11)
Push momentarily to turn power ON.
w TRANSMIT INDICA TOR [TRANSMIT](p. 13)
Lights green while transmitting.
During transmission, a humming may sound depending on the output power. This is caused by
the large current produced by the power supply
and does not indicate equipment malfunction.
e ANTENNA TUNER INDICA TOR [TUNER](p. 13)
•Lights while the antenna tuner is activated.
•Blinks while tuning and the SWR becomes 1.5:1 or
greater on the 50 MHz band.
•Goes out after slow blinking when antenna turner
cannot tune the selected antenna (SWR 1.5:1 or
greater).
r ANTENNA TUNER SWITCH [TUNER] (p. 14)
•Tur ns the antenna tuner ON and OFF (bypass)
when pushed momentarily.
- The [TUNER] indicator lights while the antenna tuner is
activated; blinks while tuning.
- While operating in the 50 MHz band, the antenna tuner
does not start automatically. Push [TUNER] for 2 sec.
to tune the antenna manually.
•Star ts to tune the antenna manually when pushed
for 2 sec.
- When the tuner cannot tune the antenna (SWR 1.5:1
or greater), the tuning circuit is bypassed automatically
after 20 sec.
t LINEAR AMPLIFIER SWITCH [AMP/PROTECT]
Turns the linear amplifier ON and OFF.
- The [AMP/PROTECT] indicator lights green when the
linear amplifier is ON. (p. 13)
- The [AMP/PROTECT] indicator lights red when the protector circuit is activated. (p. 14)
- When the linear amplifier is OFF, the [AMP/PROTECT]
does not light and the exciter’s signal is applied to one of
the output connectors or the IC-PW1’s antenna tuner.
y LOWER BAND SELECT OR [DO WN](p. 13)
Selects the lower operating band when pushed.
u AUT OMA TIC INDICA T OR [A UTO](p. 13)

!1 INPUT ANTENNA SELECTOR [INPUT](p. 13)
Selects one of 2 input antenna connectors.
!2 TRANSMIT METER-2 [METER-2]
Shows the final FET’s voltage (V
D
), SWR (Standing
Wave Ratio) or ALC (Automatic Level Control) lev el.
!3 TRANSMIT METER-2 SELECTOR
Selects the final FET’s voltage (V
D
), SWR (Standing Wave Ratio) or ALC (Automatic Level Control)
level for transmit meter-2.
!4 TRANSMIT METER-1 [METER-1]
Shows the RF output power (PO), final FET’s current (ID) or heatsink temperature (TEMP).
!5 TRANSMIT METER-1 SELECTOR
Selects the RF output power (PO), final FET’s current (ID) or heatsink temperature (TEMP) for transmit meter-1.
q OUTPUT ANTENNA CONNECTORS
[ANT1] – [ANT4] (p. 6)
Accept a 50 Ω antenna with a PL-259 connector.
w ACCESSOR Y SOCKET -1 [A CC-1]
ACCESSOR Y SOCKET-2 [ACC-2]
Enable connection to Icom exciters (transceivers).
- See the page at right for socket information.
- The [ACC-2] socket is connected in parallel with [ACC-1]
by default and can be used for connecting external
equipment such as the EX-627
AUTOMATIC ANTENNA SE-
LECTOR
, etc. These sockets can be separated by the
[EXCITER] switch. (!0)
e REMOTE CONTROLLER CABLE HOLE
[CONTROLLER](p. 10)
Used for separation of the remote controller and linear amplifier.
r ALC OUTPUT JACKS [ALC1]/[ALC2](p. 11)
Connect to the ALC input jack of a non-Icom exciter
(transceiver).
- Control voltage: –10 to 0 V DC
t SEND CONTROL JACKS [SEND1]/[SEND2]
(pgs. 8, 9)
Input terminals for transmit control. Go to ground
while transmitting.
- Max. control level: 5.0 V DC/0.1 A
- Ground level: –0.5 to 0.8 V DC
y CI-V REMOTE CONTROL JA CKS [REMO TE]
(pgs. 7–9)
Used for band control with an Icom CI-V exciter
(transceiver).
u ALC LEVEL ADJUSTMENT POTS
[ALC adj1]/[ALC adj2] (p. 11)
Adjust the ALC levels.
RCAUTION! DO NOT operate the IC-PW1 be-
fore adjusting the [ALC adj1] and [ALC adj2] pots
properly. This may damage the final FETs.
i CIRCUIT BEAKERS (p. 14)
Cut off the AC input when over current occurs.
- Circuit breaker capacity: 20 A (U.S.A. version)
15 A (Europe version)
o GROUND TERMINAL (p. 6)
Connect this terminal to a ground to prevent electrical shocks, TVI, BCI and other problems.
