The MEAN WELL DRC-40B is a 40W DIN rail power supply with a battery charger and UPS function. CH1 supplies the load at 27.6V (up to 0.95A) while CH2 charges an external 24V battery at 27.6V / 0.5A. When AC mains is present the unit powers the load and charges the battery at the same time; if AC fails, the battery supplies the load, with a battery cutoff at 20V Ā±1V to prevent deep discharge.

Key features

  • CH1 load output 27.6V, 0.95A rated (0ā€“1.45A); CH2 battery charger 27.6V, 0.5A
  • UPS function: battery takes over the load on AC failure
  • Battery cutoff 20V Ā±1V
  • AC OK and battery low alarm signals
  • DIN rail mounting
  • Input: 90ā€“264VAC / 127ā€“370VDC
  • Protections: overload, over voltage
  • Typical efficiency 87%
