The LPS-20 power supply is specially design to operate LEDs and OLEDs in voltage or current mode. An other unique function is the pulse mode which allows pulse length of = 20 ms.
Because of this featuresthe main application of the LPS-20 are FVIcharacterization of LEDs and OLEDs were one electrical parameter is controlled and the other (variable) measured. An other main application are short time measurements of high power LEDs.
The LPS-20 is offered with different current ranges to offer maximum dynamic and resolution in current control mode. The LPS-20 is full remote control via its RS232 or RS485 interface. Numerous units can be operated via the addressable RS484 which also allows combination with different units.
The rack-mount housing enables the assembling in BTH-19 bench-top housings or rack cabinets.
