Power supply protection module allows sensitive and demanding loads to be connected to the same supply without complications

摘要

PULS Power Supplies has introduced the PISA 4-channel protection module that allows sensitive loads, such as mul-tiple PLCs, to be connected to the same power supply. The device is similar to an electronic fuse, but it provides a precise switch off and no nuisance tripping. Loads that are sensitive to voltage changes are connected directly to the power supply. High-demand loads that are responsible for drops in output voltage are connected through the 4-channel PISA module, which only allows a specific amount of current to flow in order to prevent the power supply voltage from dropping below 21 Vdc.
