Delta Elektronika SM15K Series User Manual

GENERAL SM15K
10 / 32 DELTA ELEKTRONIKA B.V. rev. January 2021
diode take care the output is switched to “ON” and the
negative current setting is sufficient to hold the current.

For easier control, the optional Master/Slave interface is
recommended (see fig.4 - 5).
4.18
PARALLEL OPERATION

Without Master/Slave interface, only one unit can operate in
the Bi-Directional mode, all others can only be used as power
source.

With the optional Master/Slave interface (see fig. 4 - 6) the
power supplies can be connected in parallel without
limitations and with full functionality.
4.19
INTERLOCK

The Interlock connector at the rear panel has two pins which
have to be connected together to turn on the DC power
terminals of the unit.

As soon as the link between the 2 outer pins of the Interlock
connector is interrupted, the DC power output of the unit
shuts down.

It can be used in combination with a cabinet door contact
(safety precaution) or as an emergency brake to stop a motor
which is powered by the unit. Once the interlock pins are
connected again, the DC power output will be on.
4.20
WEB INTERFACE, ETH & USB PROGRAMMING

The web interface and Ethernet are standard available on all
units via the LAN connector at the rear side.

Also a USB connector is standard available but USB
programming is still under development for firmware version
P0140.

The web interface can be used to view and change the
settings for CV, CC+, CC-, POWER+, POWER-, Output
On/Off, configure the sink mode or optional interfaces, to
upload new firmware and configure the unit similar as with the
front display menu.

With the build-in Ethernet interface it is possible to program
the CV/CC/CP-settings, to read the CV/CC-monitors and the
status signals.
4.21
SEQUENCER PROGRAMMING

Possibility to use the unit in stand-alone automation or use as
an arbitrary waveform generator and create loops, ramps etc.

The sequencer can be controlled via the web interface and
via Ethernet programming.
4.22
FUNCTION BLOCKS

With the new SM15K series Delta introduces “Integrated
Function Blocks’.

Integrated Function Blocks are functional integrated software
blocks with predefined behavior that can be put in between a
program source and the units output controllers, see fig. 4 - 7.

By using these Integrated Function Blocks the user is able to
manipulate the units Program sources or can setup specific
simulations.

See "Function Blocks Manual" for more information and
examples.
4.22.1 LEADLESS SENSING

The Integrated Function Block “Leadless sensing” is a
functional integrated software block with predefined behavior
that can be put in between a program source and the units
output controllers.

By using this Integrated Function Block the user is able to
compensate a voltage drop falling over long or high resistive
load cables.
4.22.2 INTERNAL RESISTANCE

The Integrated Function Block “Internal Resistance” is a
functional integrated software block with predefined behavior
that can be put in between a program source and the units
output controllers.
fig 4 - 8
Different interface modules can be plugged in.
fig 4 - 6
Optional Master/slave parallel operation.
fig 4 - 7
Functions Blocks can be put in between a program
source and the units output controllers.
