The MEAN WELL AD-155A is a 155W enclosed AC/DC power supply with built-in battery charger and UPS function, designed for security, CCTV, access control and alarm systems that must keep running during a mains outage. CH1 delivers 13.8V to the load while charging a 12V lead-acid backup battery, and CH2 provides a 13.3V auxiliary output; if AC power fails, the battery takes over the load automatically.

Key features

  • Universal AC input 88–264VAC (124–370VDC), 47–63Hz, PF > 0.92 at full load
  • CH1: 13.8V, 10.5A rated (0–11.5A range), adjustable 12–14.5V
  • CH2: 13.3V, 0.5A
  • Built-in battery charger with UPS function (automatic switchover to battery)
  • Battery-low protection (10V ±0.8V) and battery reverse-polarity protection
  • Protections: short circuit, overload, over voltage
  • Free-air convection cooling (fanless), 100% full-load burn-in tested
  • Efficiency up to 80%; MTBF 1818.3K hrs min. (Telcordia SR-332)
  • Safety: UL62368-1, TUV BS EN/EN62368-1, AS/NZS 62368.1; EMC Class B
  • 2-year manufacturer warranty
