Now available: Analog interface SM15K
The SM15K series can now be controlled by the isolated analog programming interface (INT
MOD ANA). This module – originally designed for the SM3300 series – also works in the
SM15K. All that is needed is the latest SM15K firmware update. That's it! Firmware updates
are available free at our website!
There is one difference compared to the SM3300-series: INT MOD ANA can be plugged into
any available slot of the SM15K. No limitations any longer.

New! Master/Slave Interface SM15K
Delta introduces a new exciting interface for the SM15K-series: The Master/Slave interface!
The master/slave control enables programming as if it's just one big power supply system;
no need to program each supply individually.
The Master/Slave interface connects SM15K power supplies and can therefore obtain a total
output current or voltage greater than a single power supply. This interface can connect up
to 20 units in parallel operation and reach up to 300 kW! It can do this while keeping the
specifications almost equivalent to using one power supply: for instance a recovery time
of only 250 uSec!

Firmware update SM15K
Delta Elektronika offers firmware updates free of charge for all users of Delta Power Supplies.
This is part of our excellent service!
Now available is the latest firmware update for the SM15K-series: version SM15000_H0_P0107.
BI-DIRECTIONAL DC POWER SUPPLY
More Delta Power
power level: from 6kW maximum per supply to 15kW.
Increased power without compromising either specifications or lifespan is what the
SM15K-units offer. A breakthrough in power electronics technology has enabled us to
engineer features that customers demanded but were previously impossible while maintaining
very competitive prices.
Several new features are introduced in the SM15K-series compared to our current power
supply series. One is already implied in the unit name: CP is short for Constant Power! The
constant power characteristic is not new, but along with a bi-directional power flow it is! Here
are the most striking features.
Flex output for better value
The constant output power covers the output range of five separate power supplies with a
traditional rectangular VI-curve. For example:
500 Volts @ +30 Amps 500 Volts @ -30 Amps
375 Volts @ +40 Amps 375 Volts @ -40 Amps
300 Volts @ +50 Amps 300 Volts @ -50 Amps
250 Volts @ +60 Amps 250 Volts @ -60 Amps
167 Volts @ +90 Amps 167 Volts @ -90 Amps
1500 Volts @ +10 Amps 1500 Volts @ -10 Amps
1000 Volts @ +15 Amps 1000 Volts @ -15 Amps
750 Volts @ +20 Amps 750 Volts @ -20 Amps
600 Volts @ +25 Amps 600 Volts @ -25 Amps
500 Volts @ +30 Amps 500 Volts @ -30 Amps
Choosing the best output range is much easier now and offers users far better value for money.
Bi-directional power flow
Bi-directional power means the same constant power characteristic in the second quadrant for
the full 15kW. It operates like an electronic load too: previously Delta’s power supplies would
be equipped with an optional power sink capable of absorbing up to 10% of the total energy
which was dissipated via internal heat sinks. Now, the power sink is standard and can sink up
to 100% of the power without the need for dissipating lots of energy.
Power Recovery [Regeneration] Technology
With the new Power Recovery [Regeneration] Technology Delta returns full power back into the
grid and the efficiency of 95% avoids the need for expensive water cooling. Compared to
traditional electronic loads – where dissipation is 100% – there is a power loss of just 5%.
Rooms will be cooler, costs for air conditioning systems will drop significantly and overall, the
SM500-CP-90 contributes to a smaller carbon footprint.
Extremely good dynamic response to load changes
Fast response to load changes has been a challenge for a long time, especially when it comes
to changing from positive to negative current and vice versa. Previously, for applications
requiring source and sink devices, several solutions were offered such as pre-loads. The full
integration of source and sink in one device is a neater and more efficient solution. The output
voltage of a SM500-CP-90 recovers in 200µs after a load change from +90 to -90A and -90 to
Besides the constant power output and the bi-directional power flow a lot of other features are
included in the standard versions of the SM15K-series. For instance:
- Ethernet interface
- Built-in sequencer
- Digital control to adapt regulation to match load type
- Fine tune settings
There are no additional charges for these features.
The standard interface for the SM15K-units is the Ethernet interface (16 bit) with built in
sequencer. For digital I/O, serial programming, isolated contacts and master /slave operation
optional plug and play are yet available. Two other interface modules are under
- Digital I/O interface
- Interface with isolated contacts
- Serial interface with multi protocols: RS232, RS485, RS422, USB (device)
- Master/Slave interface series & parallel operation (up to 300 kW)
- Isolated analog programming interface
- Interface with simulation software (under development)

To be honest: we are proud of our new bi-directional DC power supply unit! Coming soon are
another two exciting 15kW units.

SM3000 is retired
Delta Elektronika has discontinued the production of the SM3000-series. We have
produced these power supply models since 1991. Now it's time to retire.
Defect units will be repaired for a period of 10 year after production stop. Of course against
cost price because Delta power supplies ought not to breakdown. For this reason we don't
want to make profit on repairs. Spare parts will be available for 10 years as well.
The SM3000-series have been replaced by the SM3300-series. See below overview.
