LAB/SMP DC sources overview
The LAB/SMP series consists of programmable, galvanically isolated DC sources for laboratory, industrial and service use. Three power classes of 750 W, 1,200 W and 2,400 W are each available with rated voltages from 15 to 1,200 V. This provides 24 graduated models with rated currents from 0.6 to 160 A. The units operate as sources and, depending on the selected mode, control voltage, current, power or a simulated internal resistance. PV characteristics and freely defined U/I characteristics can also be generated. Operation and measured-value display are provided at the front panel; an isolated analog interface, RS232 and optional digital interfaces support test-system integration. Most versions are 19-inch units measuring 1U by 440 mm; LAB/SMP 215 and LAB/SMP 21200 require 2U.
Key benefits
Graduated model range
Twenty-four models combine 750 to 2,400 W with rated voltages up to 1,200 V and rated currents up to 160 A.
Integrated PV simulation
PVsim calculates the U/I characteristic from open-circuit voltage, short-circuit current, MPP voltage and MPP current.
Programmable test sequences
Script operation processes up to 1,000 commands, combining setpoints, modes, delays, loops and characteristics.
Analog integration
The isolated 0–5/0–10 V interface carries setpoints, measured values and digital control and status signals.
Parallel expansion
Auto-load-share supports master-slave parallel operation of up to eight units for higher output current.
Optional high-speed version
Secondary rise and fall time of the DC output voltage is reduced by a factor of ten on average versus the standard version.
Operating principle and modes
The LAB/SMP operates as a regulated DC source. Voltage and current are set directly; depending on the mode, additional digital controllers limit power or emulate internal resistance. Interface commands have priority over analog/digital I/O, which in turn has priority over front-panel operation. Current output values remain available at the interfaces.
| Mode | Operation | Typical benefit |
|---|---|---|
| UI | Voltage and current limitation | Direct DUT supply with defined voltage and current limits |
| UIP | Voltage, current and power limitation | Additional limitation of delivered power |
| UIR | Voltage and current limitation with simulated internal resistance | Emulation of a source with load-dependent voltage drop |
| PVsim | Calculated solar-generator characteristic from Uo, Ik, Umpp and Impp | Repeatable supply along a photovoltaic U/I curve |
| User | User-defined U/I characteristic with stepped or linear interpolation | Emulation of individual source characteristics |
| Script | Timed command sequence from memory card or internal script memory | Stand-alone, repeatable test sequences |
Power range and models
Each model has a fixed rated power and an assigned maximum voltage and current range. The simultaneously usable operating point remains limited by the respective rated power: within the permissible characteristic, P = U × I and therefore, for U > 0, I = min(rated current, rated power/U).

Dynamics and regulation
| Parameter | Value | Context |
|---|---|---|
| Static voltage regulation | ±0.05% + 2 mV | DC output stabilisation |
| Static current regulation | ±0.1% + 2 mA | Current limiting and constant-current operation |
| Dynamic load regulation | < 1–3 ms, typical | Response to load changes |
| Ripple | < 0.2% RMS, typical | Residual output ripple |
| Stability | ±0.05% | Long-term constancy of output values |
| Line regulation | < ±0.1% + 2 mV | Effect of input variation |
Voltage and current rise can be adjusted as U and I slopes. A high-speed version is available for faster voltage profiles, reducing the secondary rise and fall time by a factor of ten on average.
Typical applications
PV characteristics and shading
PVsim generates solar-generator characteristics from Uo, Ik, Umpp and Impp; stored U/I curves can also reproduce defined shading scenarios.
Automotive start-up profiles
Optional KFZ12 and KFZ24 versions provide preset 12 V or 24 V start-up curves for vehicle electrical-system testing.
Stand-alone test sequences
Up to 1,000 script commands control setpoints, modes, delays and loops; optional data logging stores measured values on the memory card.
Individual source characteristics
WAVE and WAVELIN define freely programmable U/I points with stepped or linear interpolation for repeatable supply profiles.
Interfaces, automation and options
| Equipment | Status | Function |
|---|---|---|
| Front panel with graphic display | Standard | Direct operation and display of setpoints, modes, measured values and U/I characteristic |
| ATI 5/10 analog I/O | Standard | Isolated 0–5 or 0–10 V setpoint control and monitoring; soft interlock |
| RS232 | Standard | Digital remote control and measured-value queries using ASCII commands |
| IEEE488, RS485, LAN or USB | Option | Integration into laboratory software and automated test systems; USB as virtual COM port, LAN via TCP/Telnet port 10001 |
| SD card slot | Option | Load script files and log measured values at an adjustable interval |
| ATE | Option | Version without manual operation for integrated systems |
| OPT | Option | Predefined output characteristic |
| Autorange | Option | Autorange version down to 33% |
Parallel operation
For higher output currents, up to eight LAB/SMP units can be connected in parallel. In auto-load-share operation, the master defines voltage, current and OVP through the front panel or digital interface; slave units follow through the analog connection. The total current setting is determined by the number of parallel units and the current set on the master. Cable cross-sections and current distribution must be rated for the combined current.

Protection and limiting functions
Ulimit and Ilimit restrict the output voltage and output current available to the operator or an interface. The adjustable overvoltage shutdown operates from 0 to 120% of rated voltage. Protection against overcurrent, overvoltage, overtemperature and overpower is also provided. The integrated soft interlock disables the output when the interlock path is opened; it is explicitly not a machinery-directive safety interlock.
LAB/SMP series FAQ
Is the LAB/SMP bidirectional?
No. The series is a programmable DC source and does not absorb energy from the device under test during normal operation.
How do I select the right model?
The required maximum voltage, current and simultaneous power define the operating point. It must remain within the rated values and power characteristic.
Which operating modes are available?
UI, UIP, UIR, PVsim, user-defined U/I characteristic and script operation cover direct supply, limiting, simulation and timed sequences.
Can the output be controlled remotely?
Yes. Analog I/O and RS232 are integrated; IEEE488, RS485, LAN and USB are available as options.
Can the output current be expanded?
Yes. Auto-load-share enables master-slave parallel operation of up to eight units.
Can the LAB/SMP simulate a PV generator?
Yes. PVsim generates a U/I characteristic from open-circuit voltage, short-circuit current, MPP voltage and MPP current within the model limits.
Are automotive start-up curves available?
Yes, as optional KFZ12 or KFZ24 versions with a preset 12 V or 24 V start-up curve.
Are stand-alone tests with data logging possible?
With the optional memory card, script operation processes up to 1,000 commands. The optional data logger writes measured values to the card at adjustable intervals.
Technical consultation and project enquiry
To select the appropriate LAB/SMP version, we need your voltage, current and power range, intended operating mode, required dynamics, interfaces and AC supply conditions. We can support model selection, options and test-system integration.
