LPS-20

High precision controller for constant-current or constant-voltage remote operation of LEDs. Linear controller for low noise Operation.   

16 bit DAC for the current or voltage control. 16 bit ADC for the current or voltage measurement. Change between voltage and/or current mode without spikes for very fast current or voltage limiting. Sense Input to measure the foreward voltage direct at the test LED (Four contace measurement) CW or pulse mode. RS232 or RS485 remote Interface. Software development kit. Housing for 19 Inch rack use.

LPS-20-1500: max. 1500 mA (30 µA resolution). max. 24V (0.5 V resolution).

LPS-20-1000: max. 1000 mA (20 µA resolution). max. 24V (0.5 V resolution).

LPS-20-100: max. 100 mA (2 µA resolution). max. 24V (0.5 V resolution).
