The LD series features electronic loads which are suitable for
testing and characterising a wide variety of dc power sources.
They can be used to investigate the behavior of many different
types of power source such as PFCs, batteries and solar cells, as
well as electronic power supply units. The wide voltage/current
range, multiple operating modes and built-in transient generator
give them versatility to offer test solutions from the design
laboratory through to the component test area.
