With wide voltage and current ranges the ELP-34205 is an excellent series of general purpose electronic loads. Commonly used load set-ups can be easily and quickly saved and recalled from the front panel.
Dual setting and measurement ranges combined with 5 digit displays provide for high resolution. Models with a lower current range that have a higher accuracy and resolution are available on request.
- 9 Different Operating Modes
- 5 Digit Displays for V, I and W
- Short Circuit Test Function
- Adjustable Slew Rates
- Dual Setting Ranges
- 800VDC Option
Up to eight units from the ELP-34205 series 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-34205 family operating in parallel together. 50kW and 60kW models can be operated in parallel connection up to 480kW, but only with models of the exact same specification.
Each unit is able to operate independently, so that systems can be expanded or broken up as needs dictate. This approach is useful for test houses and research labs who regularly test different sized power devices.
Operating Ranges and Features
150-state memory is provided 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.
A sequencing function means that stored settings can be implemented against time. This enables the unit to carry out test routines without the need for a computer interface.
The ELP-34205 series 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 20V, the maximum amount of current that the load can sink decreases.
Constant voltage, current, power and resistance modes are provided as standard. Dynamic operation with adjustable rise, fall and plateau times enable real world loads to be accurately simulated. Dedicated short circuit, OCP and OPP tests allow power supply behaviour and protection mechanisms to be characterised.
The ELP-34205 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.
BMS Testing (Option /BMS)
The battery management system (BMS) regulates various parameters of the battery, including cell voltage monitoring, state of charge, charge/discharge current and temperature. This protects the battery from operating outside of its safe area, minimising risk of damage.
By selecting option /BMS, two complete test routines are provided for testing and certification. Actual operational parameters can be simulated, such as over charge/discharge current, over/under temperature and response time.
Interfaces and Control
Each unit features front panel control as standard. Should remote control be required then LAN, USB, RS-232 or GPIB cards can be specified. These can also be easily retro-fitted in the field by the user.
The optional analogue & digital control interfaces with panel mount emergency stop (option /803), provides you with a panel mounted emergency stop button should you need to shut down the load quickly. Additionally, this feature allows you to turn the load off from an external signal via a digital interface, as well as tap an alarms signal if the unit is in error state. You can select operating modes and read status.
The /803 option also provides a separate analogue interface which allows an input from an external source, such as an external waveform generator. The ELP-34205 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.
APPLICATION SPECIFIC GUIs
The ELP-34205 is available with a current waveform generator (option /9923). This allows the electronic load to sink different levels of energy over time. These load profiles can either be created on a PC using the waveform generator software, or imported from oscilloscope data.
If your test requirement is short term, we have a wide range of DC electronic loads in our rental range.
An ELP-34205 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.
