Your chosen unit is built with a systems interface for master/slave operation. This enables setting values to be equally shared amongst units that are configured in parallel.

Custom V/I Modifications

The LAB-SMS is an incredibly flexible product platform. We don’t just offer standard models. You can specify your own nominal voltage and current ranges often at no additional cost. For example you might have a DUT that needs exactly 850V at 2.4kW. We can provide a new unit with exactly those output ranges without increasing the lead time.

High Power Systems

If you require higher power outputs then please see our LAB-HP (3-504kW) product family.

Constant voltage, power, resistance and current operating modes are provided as standard. The PV mode allows for basic simulation of a solar cell array via adjustable I and V values.

A variety of worldwide three phase input options are available where users don't have access to a single phase line.

Units can also be built with a user specified nominal DC input voltage in the range of 250VDC-750VDC ±10% (option /DC). For example, if you chose a 400VDC nominal then the power supply would be built with an input range of 360VDC–440VDC.

Each unit is supplied with an RS-232 and isolated analogue interface, which allows the user to select the analogue voltage range to be 0-5Vdc or 0-10Vdc.

A number of optional analogue and/or computer interfaces can also be specified. The optional SD card can further provide a low cost method of recording and implementing complex waveforms.

All new LAB-SMP units are provided with free operating software. Live values of the power systems can be be viewed remotely in a simple and intuitive way. This is particularly useful when operating the power supply in a location that is remote to the DUT.

Voltage, current, power and resistance values can all be controlled through the GUI. A test sequence function allows for more complex DC waveforms to be implemented directly through the software.

Specialised PV simulation software is provided with every LAB-SMP. This allows the power system to simulate a generator's MPP tracking in both current and voltage modes. The software contains many pre-loaded solar panels from different manufacturers.

A soft interlock circuit allows users to connect the unit to an external safety device such as an emergency stop. This feature requires a high signal (+10V) to be present between two pins, otherwise the output will be shutdown. 

An ultra-compact power density of up to 2.4kW is provided in just a 1U high rackmounting case. The LAB-SMP can be built without flanges, making it ideal as a benchtop power supply.

Units can be treated to a laboratory rack or flight case integration where necessary. Multiple power systems can be fitted into the same flight case.

If your test requirement is short term, we have a 150V/2.4kW LAB-SMP unit in our rental DC sources range.

These PSUs are found in a wide variety of fields from automotive applications and general lab work to battery charging and automatic test systems.
