＊Applicable a wide eange of input voltages, but DC13.8V/20A at AC 70V and
140V.
＊Output voltages : 10-30v, 25A continuous is available as a version for ss-505
When you place order, please make sure whether ss-505 or ss-505H.
■ CAUTION
1) PLEASE DON`T USE AS A CAR BATTERY CHARGER.
2) Use only in a well ventilated place.
3) Connect the AC plug directly to an AC wall socket.
4) Connect the chassis of the unit to the ground earth.
5) At high internal temperatures, the protecttion circuit will limit the output current.
6) Due to the presence of large magnetic field, please ensure that the output cable of
the SS-330W is kept as far away from your antenna connecting cable as possible.
7) Be sure to use at least 5.5mm diameter wire.

Daiwa SS-330W Power Supply AC Modification
(DX Engineering Part number DWA-SS-330W)
Instructions for changing the operational input voltage from AC 110V to AC 230V
CAUTION: HIGH VOLTAGE IS PRESENT
Do NOT alter or in any way attempt to make any changes other than described below.
Caution must be used when opening or modifying the power supply.
Ensure the power supply is turned OFF and un-plugged from any AC power source.
DX Engineering is not the source of this modification information. This information was obtained from the Daiwa web site.
DX Engineering is not responsible for any damage or liability involved in this modification in regards to personal safety or
damage to any equipment as a result of this modification. This modification is the sole responsibility of the user.
1. Prior to any modification, be absolutely positive the power cord is removed from the back of the unit
2. Remove the 6 screws holding the top of the case in position.
3. Pull the large blue wire with spade connector off from the spade receptacle marked AC 100V on the circuit board.
4. Push the blue wire with
spade connector onto the
spade receptacle marked
AC 230V on the circuit
board firmly.
5. Replace the upper cover
with the original screws.
6. IMPORTANT - The 8A
fuse installed is intended
for 110V. After
changing the input
voltage to 230V the fuse
must be changed from
8A fuse to a customer
supplied 4A fuse. It is
also recommended that a
customer made label be
put on the rear of the unit
as a reminder that the
input supply voltage and
fuse size have been
changed.
7. A customer supplied
replacement power cord may be required depending on the customer’s VAC socket being used.
