DPS-3 USER’S GUIDE

The factory setting for the digital adapter is adjusted in accordance with the 2.6 ampere that is the
maximum current you can draw. You can reduce this current to the +300Ma. current limit depending
on the importance of the equipments you use. This helps you protect the equipments that are connected
to you. When the equipments are in the breakdown formation phase, they draw more current than they
normally do. For the digital adapter to feel this, it needs current limit. For this, all the equipments that
are going to be connected to the digital adapter must be put into operation mode and the current that is
drawn in the current display must be under 2.3 ampere.

WHAT IS THE DIGITAL CURRENT LIMIT ?

ENABLE THE DIGITAL CURRENT LIMIT

1234 which is the factory setting code is entered. Then press the key # and digital current limitation is
put into operation with the affirmation sound. From that moment on, the current that is 300Ma more
than the current that is displayed on the screen can not be drawn. When it tries to draw, the output
current is cut and the letters “oL” which is the Over Load symbol starts to blink on the Ampere screen
together with the warning sound. This situation goes on until you press the * key. If the equipment does
not turn back to its normal condition although you press * key, then there mus certainly be a problem
with the equipments that are connected or extra current is being drawn from the digital adapter without
your control. When you find this problem, you can operate the digital adapter again by pressing * key.

1234 which is the factory setting code is entered. Then press the key # and digital current limitation is
put out of operation with the affirmation sound. From that moment on, from the digital adapter, you can
draw 2.6 ampere which is the factory setting value. If more than 2.6 ampere current is drawn, the letters
“oL” which is the Over Load symbol starts to blink together with the warning sound as in the case of
digital current limitation. In this case you can operate the digital adapter again by pressing * key and
diminishing the load that is connected to the digital adapter.

DIGITAL PROTECTION AGAINST SHORT CIRCUIT AND HEAT

Digital Adapter has protection against short circuit. In case of short circuit in the voltage in put, the
letters “oL” which is the Over Load symbol starts to blink together with the warning sound as in the
case of digital current limitation. In this case, you can operate the digital adapter again by checking
equipment connections that are connected and the voltage output of the digital adapter and pressing
* key. In addition to this, protection against thermal heat gets into service at 125 C

INSTALLATION & PROGRAMMING

You can operate the equipment by plugging the power cable, that is given together with the equipment,
to the 220 Vac. input socket that is at the back of the equipment. While the equipment is opennig, the
letters OP En appears on the screen that is on the front side, later on Voltage screen the number 12
appears and on the Ampere screen the numbers 00 appears. The numbers that is written on the voltage
screen represent the voltage. The factory setting is adjusted as 12Vdc. You can draw 2.6 ampere.
