LPS Series Power Supplies for LEDs and Tungsten Lamps
Gigahertz-Optik manufactures electronic devices like
lamp power supplies, mobile and bench top optometers and instrumentation that can be combined with
other light measurement devices for complete application set-ups in the field of light measurement
(radiometry, photometry and colorimetry) optoelectronic component qualification and (OPM) optical properties of material testing. The modular concept of the 19”
3HE housings enables individual set-ups based on
customers requirements. Electronic devices are installed into the BTS-19 series housings that are available in bench top or in rack mount style.

LPS-20 Single Channel 1500mA/24V LED Power Supply
The LPS-20 is a microprocessor-based current and
voltage source especially designed for the operation of
LEDs, OLEDs and other light sources requiring high
resolution, very low noise operating voltage and current that is controllable and measureable. It is set-up
for full remote control operation in CW or Flash mode
via its RS232 or alternative RS485 opto-coupler isolated interface. DLL and Labview VI are available.
Its design includes two high resolution 16 bit digital to
analog converters for precise current and voltage control. It can be operated either in constant voltage or
constant current mode. The variable (current or voltage) can be measured with a high resolution ADC. To
avoid unintentional power loss at the linear control
element its input voltage is set by a DC/DC converter
to the optimum voltage needed. Beside the CW mode
the output of the LPS-20 can be controlled for a defined time (single pulse) with rise time as short as
500µs (load dependent). Four different versions with
different maximum output current level are supplied:
LPS-20-10:
max. 10mA with 0.2µA resolution
max. 24V with 0.5mV resolution
LPS-20-100:
max. 100mA with 2µA resolution
max. 24V with 0.5mV resolution
LPS-20-1000:
