SFL

NEW RANGE High end programmable 300W and 1,000W DC electronic loads

The series comprises of 300W (3U high half-rack) and 1,000W (3U high full-rack) power levels and either a 120Vdc or 500Vdc maximum rating. The units operate in 7 different load modes and 4 operating modes. This allows the user to perform up to 17 different load tests on DC power supplies, fuel cells, solar cells, batteries and components to fully characterise their performance.

The loads can be programmed for multiple load types, including constant current, constant resistance, constant power, external control, short circuit, and constant voltage with a current limit. The operating modes are normal, pulsed load (dynamic time and frequency), complex waveform generation and "sweep" to test and determine a product's voltage-current, overcurrent or power limit characteristics. Eight load settings can be stored internally.

Up to 10 units may be paralleled in a master-slave arrangement for higher power requirements. Multiple SFL loads can also be connected to separate devices for synchronised load control and dynamic operation. The series can be programmed using analogue or digital signals, with an optional ripple and noise measurement and IEEE interface.
