Programmable Benchtop
DC Power Supplies

Accurate
The programmable benchtop DC power supplies
operate single-supply or intricate multi-power
applications such as remote sensing calibration
systems. Light measurement system upgrades
and sensor calibration systems are easily
implemented through a wide variety of interchangeable light source assemblies, lamp standards,
and complimentary power supplies.
The power supplies are designed to accurately
provide DC current to Labsphere’s internal andexternal reference lamps and other light sources.
The current output is selected and set in the LPSconfiguration software included with the power
supply. On/Off control is done through the front
panel or external trigger.
Value• Programmable regulated DC current• Programmable regulated DC voltage• Controlled current ramp up• Lamp operation timer• Easy on/off operation• Front panel or remote control• Current, voltage readback
