Overview

What it is

The MEAN WELL DRC-180B is a security power supply with battery charging from the DRC-180 series (180 W Single Output with Battery Charger (UPS Function)), rated 27.6 V, 4.5 A, 179.4 W.

What it is used for

Powers 24 V security loads such as access controllers, electric locks and alarm panels while charging a standby battery on a separate charger output, and keeps the load running from that battery during a mains failure. AC OK and battery low alarm outputs can be wired to a panel or controller. MEAN WELL lists applications such as security systems, access systems, alarm systems, ups systems.

Key features

  • Universal AC input, full range, with built-in active PFC.
  • AC OK and battery low alarm signals via relay.
  • Protections: short circuit, overload, over voltage, over temperature.
  • Battery low protection and battery reverse polarity protection by fuse.
  • Mounts on DIN rail TS-35/7.5 or 15.
  • Operating altitude up to 5000 metres.

Key Specifications

  • Output Voltage: 27.6 V (CH1 load output).
  • Rated Output Current: 4.5 A (CH1).
  • Battery Charging Voltage: 27.6 V (CH2 battery charger output).
  • Charging Current: 2 A (CH2 rated).
  • Input Voltage Range: 90 to 264 V AC; 127 to 370 V DC.
  • Rated Output Power: 179.4 W (CH1 plus CH2).

Buying considerations

Size the unit with headroom above the connected load and check the derating information in the datasheet for high ambient temperature or low input voltage. Other models in the same series are listed on this page.

Installation considerations

MEAN WELL treats this unit as a component of the final equipment, so approvals and EMC performance should be confirmed for the complete installation. Wiring and safety details are in the official datasheet linked below.
