Up to eight ELP-HIVOLT units can be arranged in parallel configurations. It is possible to connect 5kW to 40kW models with different nominal values, up to a maximum of 320kW. For example, a 5kW system and a 40kW system can be operated together. 

The diagram shows eight different models from the ELP-HIVOLT family operating in parallel together. 50kW and 60kW models can be operated in parallel connection, but only with models of the exact same specifications. 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 provided as standard, which allows quick initialisation and limit-setting of the unit. This makes the ELP-HIVOLT both dependable, and mobile as an on-site load tester. 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. 

Each ELP-HIVOLT is able to operate at maximum current across most of its voltage range. This allows one system to test many different types of devices. When operating below 55V, the maximum amount of current that the load can sink decreases.

Standard operating features include OVP & OCP tests, dual voltage and current ranges, 150 state memory as well as CC, CV, CR and CP modes. In dynamic mode adjustable rise, fall and plateau times allow testing of high voltage DC energy, such as renewables. Dedicated short circuit, OCP and OPP tests allow power supply behaviour and protection mechanisms to be characterised.

The ELP-HIVOLT 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. 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-HIVOLT 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 a wide range of DC electronic loads in our rental range.
