Dantech 8A 12V Dc Or 4A 24V Dc Power Supply With Ups And Monitoring

  • Selectable 12V or 24V DC output
  • Integrated UPS battery back-up function
  • Mains fail signalling
  • Multi-purpose independent relay
  • 320 x 255 x 90cmm Mild steel powder-coated enclosures
  • Input 230V AC @ 50Hz (+/- 10%)
  • Includes a spares-bag mounting kit

The DA449 power supply provides either a 12V DC (13.7) or a 24V DC (27.4) output. The output voltage can be changed from 12V to 24V by using a simple selector plug. These units provide two separate output terminal pairs and can house and charge two 12V 7Ah VRLA batteries.

Typical uses are for powering door access controllers, electric releases and magnetic-locks.

Selectable 12V or 24V DC output

The output voltage can be changed during installation from 12V to 24V DC by using a simple selector plug.

Integrated UPS battery back-up function

A 7Ah VRLA battery can be placed in the mild steel enclosure and connected to the battery terminals of the PCB. This power supply will automatically float-charge the battery to capacity, providing continuous uninterrupted power from the battery if mains power is unavailable.

Batteries are not included. This unit can be used with or without batteries fitted.

Mains fail signalling

These units are equipped with separate SPCO (Single-Pole Change-Over) contacts for mains-fail monitoring. If mains power is not detected for approximately 30 seconds, the relay contacts will change-over. Ideal for switching equipment or signalling to other systems.

Multi-purpose independent relay

This undedicated SPCO universal relay is electronically isolated from the power supply. It can be driven from a 12V or 24V DC supply. A typical use for this relay would be interfacing a fire panel with the power supply to de-power magnetic-locks in the event of a fire condition.

Mild steel powder-coated enclosures

Precision-made from mild steel and powder-coated white for an easy-clean, durable finish, this enclosure is ideal for wall mounting. The enclosure includes knock-outs for cable gland entries.

Input 230V AC @ 50Hz (+/- 10%)

Designed to operate on UK standard mains power, this unit will accept a mains-powered input of 230V AC @ 50Hz (+/- 10%)

Includes a spares-bag mounting kit

Each unit includes a spares-bag for the installation engineer. This kit contains useful items, such as cable glands, wall plugs and fixing screws.
