4. Operation and application
a) Connection
Make sure that you are using a 230V/50-60Hz line voltage. Then plug in the power plug, turn the control
knobs right (0V / 0A position) and switch the unit on. Chose the voltage your need. You can set-up the
current by switching the Imax switch. When outputcurrent reach the preseted value, mode will change
into constant current.
Caution!
Parts of the unit ( heatsinks ) will be hot when maximum current is used. The unit has a build in
overtemperatur protection, which will switch the unit temporally off when 90°C are reached. After a period
of cooling the unit automatically switches on.
Caution!
Do not cover the ventilation holes. You must ensure that there are at least two inch's clearance around
the unit. Take care that the cables of your load are tight connected with the unit. Even low voltage can
cause electric sparkles that can harm the terminal and your load.
b) setting up the voltage (with no load)
Turn the coarse knob for the current a little clock wise to ensure that the current regulator is not set to
zero. The LED for constant current is off and the LED for constant voltage is on then. Now you can set up
your voltage.
c) setting up the current
Push the switch Imax. The current display now shows the value for the maximum current you can use.
Set up the current and release the switch. The unit will now change in to constant current mode if the
current through your load is reaching se value you set up.
caution!
Pay attention on the safety instructions in chapter 2 of the manual..
