LDB120 Series is a single phase 120 W integrated DIN Rail Battery
Charger / DC UPS Power Supplies, suitable for wide variety of
industrial applications.
In case of mains or unit failure the DC UPS function enables the power
supply to feed the load from the battery without any interruption, until
the mains is recovered or the battery reaches the “Deep Discharge
Voltage” threshold.
These units have received excellent market approval for their high
efficiency, excellent reliability and compactness. Simple but elegant
look and easy installation make them market leaders for various
industrial applications.
LDB120 Series are isolation devices suitable for SELV and PELV
circuitry and are designed to be mounted on DIN rail and installed
inside a protective enclosure.
Input: 120 - 240 VAC
