Technical Description

The PS100 can also be used as a separate auxiliary 12-V power supply to power remotely located sensors or peripherals, such as a multiplexer located at a distance from the datalogger enclosure. However, to avoid errors in analog measurements and ground loops, the power supplies must share a common ground.

The PS100 replaced the PS12LA power supply. The PS100 offers a slightly smaller footprint and height than the PS12LA. It also allows access to the Power Switch and LEDs without removing the lid of the power supply.
