All models can be operated in constant current, voltage, power, and resistance modes. The adjustable internal resistance make this range ideal for automotive simulation as well as general laboratory and production work.  

A PV operation mode is also provided as standard. This enables a photovoltaic generator's MPP tracking to be simulated. The MPP is available in both voltage and current modes.

A three phase AC input cable is provided for all units.

Front Panel HMI

A large front panel display is provided which indicates all relevant output quantities simultaneously. Output values can be preset and read prior to releasing the output.

Interfaces

Each unit has an RS-232 and isolated analogue interface as standard. Additional computer control interfaces are provided with selected models which includes USB, Ethernet and IEEE 488.2. Please contact ETPS if you require a specific interface.

SD Card/USB Port

An SD card slot or USB port is provided with selected models. This is a useful feature to enable the DC Source to follow pre-determined voltage and current curves. Data is programmed on a PC using  text or .WAV formats. It can then be simply transferred to an SD card or USB drive and recalled from the front panel of the LAB-HP. 

The data card can also be used for data logging. Output values can be recorded at intervals of 1 sec to 71 mins. The front panel display indicates when the unit is logging data and will alert the user when the memory card becomes full.

Operating software can be provided with selected models. 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.

A specialised PV simulation software package is also provided with certain LAB-HP models. 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.

Selected models feature 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.

Each LAB-HP system is supplied in its own wheeled flight case for ease of transport.

If you are looking to purchase a system, new LAB-HP units can be found in our DC sources range.
