General
Main characteristics of this series are state of the art technology, compact
design and a wide type spectrum.
The units may be used as constant voltage supply with current limiting or
as constant current sources with voltage limitation. Current and voltage
are continuously adjustable by means of coarse and fine potentiometers (on
double power supplies only voltage with fine potentiometer).
High reliability - even under most extreme conditions - is provided by automatic
transformer switching, MOS-FET power stages and a temperature-controlled
ventilation regulation with functional monitoring. The unit is designed without
ventilation slots at the top and the bottom and has no external heat sinks.
Volt- and Ammeters
The units are equipped with separate volt- and ammeters, class 2,0 (the ammeter
of EA-PS 3300 can be switched between both outputs).
Overload Protection
All units are provided with overload protection. The current can be set between
0 and 100% of the rated current in coarse and fine mode (EA-PS 3300 only
coarse).
Overvoltage Protection
All units are equipped with an overvoltage protection (OVP). The threshold
of the OVP can be set by means of the trimmer "OVP" on the front panel
within the range of 0V and 20% above the rated voltage.
Operation Mode Indicator
The LED "CV" indicates that the unit is operating in constant voltage
mode, the LED "CC" indicates that the unit is operating in constant
current mode.
The LED "Error" indicates that the unit output was switched off either
by the integrated overtemperature protection or by the overvoltage protection.
Operation in Parallel or Series
It is possible to operate two or more units in series or in parallel.
Options
The units can be supplied with the option "REM" and "Sense".
The option "REM" provides each a programming input (0...10V) and a
monitor output (0...10V) for voltage and current. These inputs resp. outputs
have a common ground contact which is connected to the +output. At the back
of the unit there is a 9pole SUB-D socket as well as the sense input.
The remote "Sense" can be used to compensate the voltage drop up to
1V on the each load cable.
