OPERATING MANUAL ES300
8 / 13 DELTA ELEKTRONIKA B.V. rev. Sept. 2019
3 OPERATING
3.1 OPERATING THE UNIT FOR THE FIRST TIME

Check that there is no condensation on the unit. If there is,
allow some time to dry.

Set the program switches on the rear panel on MANUAL
(=factory default).

Switch on unit.

Turn both the CV and CC potentiometer a few turns clock
wise. A voltage should now be present on the output.
3.2 ANALOG PROGRAMMING

Put the appropriate switch(es) in the position PROGRAM.

Connect the programming voltage source(s) (0 - 5 V) to the
ANALOG PROG. CONNECTOR on the rear panel (see fig. 3
- 1 and - 2). Always use a shielded cable for programming.

If only the voltage is programmed, the maximum current can
still be set with the CC potentiometer and vice versa. If this is
not desirable the CC or CV can be set with an external
potentiometer, in order to have a fixed setting.

CAUTION: The analog inputs are not isolated from the output.
The Ø of the prog. input (pin 1) is internally connected to the
negative output. To protect the internal wiring a 650 mA self-
resetting fuse is connected in series (see fig. 3 - 4).

For isolated analog programming the ISO AMP MODULE is
recommended to avoid earth loops.

To avoid hum or noise, the programming cable may have to
be twisted in some cases.

To program the unit by current instead of voltage, simply use
a parallel resistor as a current to voltage converter.
3.3 Ethernet / IEEE488 / RS232 PROGRAMMING

The internal Ethernet interface PSC-ETH and the internal
RS232 interface PSC-232 are factory built in.

For the external interface PSC-488 module simply connect
the programming connector of the power supply with the
mating connector of the interface (pin compatible). Always
use a shielded cable.

Connect the interface with the computer.

On the power supply set both programming switches in the
position program.

Both CV and CC can be programmed and read back.

The CC status can also be read by the computer.
3.4 MONITORING OUTPUTS

The 5 V level is compatible with most interfaces.

Monitoring outputs can drive a meter directly (see fig. 3 -3).
3.5 STATUS OUTPUT

The status output has a separate Ø connection (pin 8) to
avoid unwanted offsets in the programming. This pin is
protected with a 650 mA self-resetting fuse.
3.6 REMOTE SHUTDOWN

The remote shutdown can be operated with +5V or a relay
contact (see fig. 3 - 5).
3.7 MASTER / SLAVE SERIES OPERATION

For series operation the MASTER / SLAVE SERIES
ADAPTER must be used. With this adapter the master can be
the upper or lower unit which, in particular for high voltages is
Warning! 0Vprog. and Minus DC power
are internally connected.
