LDB120-24 Bel Fuse

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 Output: 12 or 24 VDC model dependent To be used with Lead Acid batteries or lithium batteries (compatible with Lead Acid batteries) Efficiency up to 86% Economic solution for general purpose applications Instantaneous LOAD switch BACKUP mode 2 LDB120 Series LDB120-12 120 - 240 VAC (140 - 345 VDC) 1 12 VDC 7 A LDB120-24 120 - 240 VAC (140 - 345 VDC) 1 24 VDC 5 A Technical parameters are typical, measured in laboratory environment at 25C and 240 VAC / 50 Hz, at nominal values, after minimum 5 minutes of operation.
