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 LDB120 Series 2 LDB120-12 120 - 240 VAC (140 - 345 VDC) 1 12 VDC 7A LDB120-24 120 - 240 VAC (140 - 345 VDC) 1 24 VDC 5A Technical parameters are typical, measured in laboratory environment at 25C and 240 VAC / 50 Hz, at nominal values, after minimum 5 minutes of operation.
