Important Details
Unpacking
Check the contents after unpacking for missing parts or
accessories and the unit for any apparent mechanical damages
and loose parts inside the unit. In case of a transport damage
please inform the seller immediately. In that case do not take
the unit into operation.
Commissioning
For safety reasons the unit may only be operated at a mains
power connection provided with a safety ground or via an
insulating transformer safety class . The air in- and outlets
on the back side may never be obstructed in order to ensure
proper cooling.
Mains power voltage selection and fuse replacement
Before putting the unit into operation make sure that the
available mains power voltage and the setting of the input
voltage selector on the back have the same value (115 or
30 V). If it is required to adjust the input selector to the mains
power voltage value, an input fuse with an appropriate voltage
value has to be fit as well. The fuse may only be changed or
replaced whilst the unit is disconnected from the mains power
line. The fuse and the respective values are shown on the back
side of the unit.
General
The power supply series EA-PS 3000B (600 – 650 W output
power) is of primary switching technology and is provided with
a Power Factor Correction circuit (i.e. PFC, sinusoidal input
current). This series is distinguished by its compact built-up,
lightweight, excellent electrical values and extended operational
features, such as fine and coarse adjust of output voltage and
current, preset function for output voltage and overvoltage
protection (OVP) and the display of various operation
statuses. Cooling is provided via a temperature controlled fan.
Furthermore, this series features an analogue interface (0-10V)
for remote control and can, in addition, be fitted with an external
USB interface adapter (EA-UTA1).
Controls and displays
Output voltage and current can be preset through coarse and
fine potentiometers placed on the front panel or via 0...10V
through the analogue interface. The respective values are
shown on the 3-digit 7-segment LED meters or via the analogue
interface (0...10V).
Whilst pushing the preset button, the preset current and the
preset overvoltage protection value (i.e. OVP, setting through
the 10-turn potentiometer on the front), are displayed on the
LED meters.
T h e r e g u l a t i o n m o d e i s i n d i c a t e d v i a t w o L E D s .
LED CV = constant voltage mode
LED CC = constant current mode
Furthermore, the LEDs on the front panel show the following
operation conditions.
LED Standby = Shut down by analogue interface
LED OVP = Shut down by overvoltage (OVP)
LED OT = Shut down by overheating (OT)
LED External = Analogue interface active
Output terminals
The output is provided through two safety sockets on the front
panel and in addition via screw terminals on the rear side. The
connections for "remote sensing" .i.e. to compensate the voltage
loss on the load wires, are placed on the rear side as well.
