Product details MEAN WELL LAD-120B

A compact and powerful AC/DC power supply with backup function (UPS), designed for security and fire systems. This low-profile 120 W power supply combines stable power delivery with a backup mode, ensuring uninterrupted operation of connected devices even during a power outage. It supports charging lead-acid and lithium-ion batteries and is equipped with advanced protection features. With high efficiency and a wide input voltage range, it is ideal for critical applications requiring reliable power.

  • Built-in battery charger and UPS function: enables continuous power supply to connected devices even during a mains power failure.
  • Support for lead-acid and lithium-ion batteries: provides flexibility in choosing the battery type according to specific application needs.
  • Forced UPS mode for battery maintenance: improves battery lifespan through regular maintenance.
  • Protective features: include short-circuit, overload, overvoltage, overheating, low battery voltage, and reverse battery polarity protection (without damage).
  • TTL signals for status detection: provide information about AC OK, battery disconnection, battery reverse polarity, low battery voltage, fully charged battery, and discharging.
