CONFIGURATION & CALIBRATION ISO AMP
5 / 7 DELTA ELEKTRONIKA B.V. rev. Febr. 2021
5 OPERATION & CALIBRATION
5.1 GENERAL

If you have a question about the unit, please contact our
engineers using the address Support@Delta-Elektronika.nl.

In case the unit is defect, please first fill out the RMA-form
before sending the unit to us. Adding a detailed fault
description will help us to repair the unit as soon as
possible. Do not try to repair the unit yourself.

On our website the RMA-form can be found under
'Support'.
5.2 POWER SUPPLY SET-UP

For settings of remote programming and monitoring please
refer to the power supplies’ manual.

Note that the warning that the Ø of the programming input
of the power supply is no longer connected to the minus
DC Power Terminal, when the ISO AMP is used.

The ES- and SM-series power supplies do not need any
maintenance or calibration. However, care must be taken
that the cooling of the unit is not obstructed.
5.3 ISO AMP CONFIGURATION

The ISO AMP can be configured for both 5V and 10 V
signal levels. Selecting a signal level is done by closing or
opening DIP-jumpers.

Take proper ESD precautions before setting the jumpers.

See fig. 5 - 1 for lay-out for ISO AMP PCB P512 rev.B.

A closed jumper is 0- 5V, an opened jumper 0-10 V. The
signal level for each of the four analog channels can be
selected individually. See table 5 -1.

The full scale of the analog channels of the ISO AMP is
factory calibrated within 0.1% for a 5 V signal level.

Configuring jumper J1...J4 for 10 V signal levels without re-
calibrating can introduce an extra full scale error of 0.1%.
Table 5 - 2 shows the full scale calibration trimmers.

Warning: before proceeding with the calibration of the ISO
AMP make sure that your measuring equipment has the
correct voltage and current rating.
5.4 ISO AMP VOLTAGE CALIBRATION

Connect a suitable, high accuracy volt meter to the output
terminals of the power supply and put the CV programming
switch on the power supply in the position ‘PROG’.

Apply 5.000 V or 10.000 V (depending on the jumper
setting) to the CV
PROG
input.

Calibrate the output voltage of the power supply with R51.

Connect the volt meter to the CV
MON
connection and
calibrate the CV
MON
signal with R29.
5.5 ISO AMP CURRENT CALIBRATION

Switch off the power supply, connect a suitable, high
accuracy current meter across the output terminals of the
power supply.

Put the CC programming switch on the power supply in the
position ‘PROG’.

Apply 5.000 V or 10.000 V (depending on the jumper
setting) to the CCPROG input.

Calibrate the output current of the power supply with R40.

Connect a volt meter to the CCMON connection and
calibrate the CCMON signal with R18.

Warning! Wrong calibration can damage the unit.
5.6 Other

If there is a fault or inaccuracy that cannot be compensated
with the calibration range, please fill out the RMA-form on
our website
www.DeltaPowerSupplies.com . See previous
paragraph 1).
