To improve productivity when using lighting to power a vision system, Smartek Vision has developed the HPSC series of LED current controllers. The HPSC4 four-channel controller is designed to work as part of a vision solution, be it for the flexibility to capture fast moving objects with maximized picture sharpness or where precision levels of illumination are required. Driving a broad range of LED illumination, it comes with a digital regulated buck and boost switching power supply with up to 120W output. The four individually controllable input and output channels enable asynchronous operation and full control over light intensity, timing and synchronization, as well as over modulation of one of more lights for different lighting scenarios via a single controller.
The HPSC4 produces up to 40A pulses at a maximum of 48V on the output. For precise synchronization and strong overdrive options the HPSC4 comes with opto-isolated trigger inputs and separate output lines for external synchronization. The input-to-output delay of down to 2µs allows pulses with a resolution of up to 1µs/1mA and durations from 1µs to 60s. The various HPSC4 operating modes – from external, internal and software triggered to continuous operation – allow the synchronization type best suited to a specific application to be selected.
