Up to eight units from the ELP-34105 series can be arranged in parallel configurations. It is possible to connect 5kW to 40kW models, up to a maximum of 320kW. The diagram shows eight 40kW models from the ELP-34105 family operating in parallel together. When operating in master/slave operation, a number of test modes are not available. Please see the datasheet for more information.

Each unit is able to operate independently, so that systems can be reconfigured, expanded or broken up as needs dictate. This approach is useful for test houses and research labs who regularly test different sized power devices. Individual units can be used for the day to day testing of multiple small devices, then grouped together for larger projects.

150-state memory is available as standard, which allows quick initialisation and limit-setting of the unit. This makes the ELP-34105 both dependable, and mobile as an on-site load tester.

The LCD display simultaneously shows Voltage, Current & Power. A sequencing function means that stored settings can be implemented against time, enabling the unit to carry out state-dependant and complex test routines without the need for a computer interface. 

The ELP-34105 series is able to operate at maximum current from 1000VDC to 0.7VDC. This allows one system to test many different types of devices. When operating below 0.7V, the maximum amount of current that the load can sink decreases.

The 5kW unit is supplied with a carry harness for ease of installation.

Standard Modes

All units can operate in CC, CV, CR, CP, CV+CC, CV+CP, MPPT, Dynamic and Short Modes.

The ELP-34105 series has a total of 5 battery discharge modes. These simplify test set up for users, whilst avoiding conditions which could result in permanent battery damage due to over or under voltage.

Front panel control is provided as standard with each unit. Should remote control be required then LAN, USB, RS-232 or GPIB cards can be specified. Interface cards can also be easily retro-fitted or even swapped in the field by the user, further expanding its capability.

The /802 option provides a separate analogue interface which allows an input from an external source, such as an external waveform generator. The ELP-34105 will track the signal in CC, CV or CP modes, varying its load current proportionally according to the 0-10VDC signal. You can also monitor the sink voltage and current.

If your test requirement is short term, we have multiple ELP-34105 units in our rental DC electronic load range.

An ELP-34105 system was used by Brunel University London to perform discharge tests on a custom battery pack design they had created. The versatility of the load means that it is used on a variety of projects by multiple departments, from PV array testing to loading fuel cells.
