DATCOM-RTU - module UPS
Back-up module UPS
Module UPS serves for backing-up supply voltage for system modules and for communication devices (modem…). For feeding of other devices (for instance external sensors) is back-up supply voltage also brought to module terminal.
Module ensures switching mains supply or from accumulator depending on presence of voltage from network source. It protects accumulator against total discharging by unfastening of load.
Circuits for charging accumulator are not part of module UPS.
