Product information

Description

Mean Well LAD-120B is a 120W single-output battery charger and UPS that provides a regulated 27.6V DC output with up to 3.4A charging current. Designed for continuous DC power delivery and battery backup, it integrates charging circuitry and an automatic transfer function to keep connected equipment powered during mains interruptions. The unit supports sealed and flooded lead-acid battery types and is intended for installations where a stable 27.6V supply and reliable failover are required, such as telecommunications, industrial controllers and access control systems.

Advantages

The LAD-120B combines a precision battery charger with an uninterrupted power supply function in a compact enclosure, delivering a constant 27.6V output while maintaining battery float charge. Its 120W rating and 3.4A charge capability allow it to support moderate loads while keeping the battery charged. Built-in protections for over-voltage, over-current and reverse connection protect both the charger and the connected battery. The design facilitates easy integration into 24–28V DC systems and reduces the need for separate charger and UPS components.

Suitable for

  • Telecommunications equipment and base stations requiring 27.6V backup
  • Industrial control panels and PLCs operating from a 27.6V DC bus
  • Access control, security and surveillance systems with battery standby
  • Small server racks or network appliances needing regulated 27.6V supply and failover

Key specifications

  • Output voltage: regulated 27.6V DC
  • Maximum charging current: up to 3.4A
  • Rated power: 120W single output
  • Battery types supported: sealed and flooded lead-acid compatible
  • Functions: combined battery charger and automatic UPS/backup transfer
  • Protections: over-voltage, over-current, reverse polarity protection
  • Form factor: compact DIN-rail / chassis-mount compatible design (check mounting option)

How to use

Install the LAD-120B according to local electrical codes and the manufacturer’s mounting instructions, ensuring proper ventilation and secure mounting. Connect the AC input to a suitable mains supply and wire the DC output to the load and to a matched lead-acid battery following correct polarity. Configure battery capacity and charge settings if applicable, then power on the unit. During normal operation the charger provides regulated 27.6V to the load while maintaining the battery on float charge; on mains failure the unit transfers to battery supply to maintain output continuity.

Usage recommendations

Use a battery with compatible voltage and sufficient capacity to meet runtime requirements. Periodically inspect battery connections and charge status, maintain adequate ventilation around the unit, and replace batteries according to manufacturer aging guidelines to ensure reliable backup performance.
