■ SPECIFICATIONS
*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
30Amp switching power supply How to adjust the input voltage from AC 100V to AC 220V use.
CAUTION: HIGH VOLTAGE IS PRESENT ! Do not alter or in any way attempt to make
any changes other than described below
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.
IMPORTANT The 8A fuse installed is intended for 110V. After changing the input voltage
to 220V the fuse must be changed from 8A to 4A.
