PULS's Pisa 4-Channel Protection Module
Pisa 4-channel protection module allows sensitive loads and demanding loads to be connected to the same power supply. Similar to an electronic fuse but at lower cost, the 4-channel package provides more precise switch-off and no nuisance tripping. Sensitive PLC loads are connected directly to the power supply. Demanding loads that are most responsible for output voltage drops are connected through the 4-channel module that prevents power supply voltage from dropping below 21 Vdc.
