Electronic loads offer advanced and economical power supply testing
Enabling simple and economical testing of a wide range of power supplies, on-board chargers, batteries and other power electronics components, the new 63200E series high power DC electronic loads has been launched by Chroma. Available from MDL Technologies, the programmable loads offer market leading accuracies of up to 0.02% + 0.02% FS for voltage and 0.1% + 0.1% FS for current.
The range has three operating voltage options of 150V, 600V and 1200V, with models covering power ratings from 2-24kW and up to 2000A in a single unit. When greater power is required up to 20 units can be linked together in parallel in a master/slave configuration to produce a total power of 480kW.
Among the features included are CC, CR, CV and CP modes, high speed programmable dynamic loading, short circuit simulation and smart fan control.
"These compact models save space in the laboratory and other test environments, and offer an ultra-high power density of 6kW in a 4U chassis," said MDL managing director Mark Lucock.
Applications include high power EV battery discharge testing, charger stations, fuel cells, AC/DC power supplies, on-board chargers and burn-in testing.
Also available from MDL is the even more powerful Chroma 63200A series, which includes functions such as dynamic synchronous control to allow the generation of complex multi-channel transient profiles.
They also accept digital data from DAQ cards or analogue data from function generators to allow user defined waveforms to be created.
