Technical description

ECO 24V 1A Mini is a compact and reliable battery backup for 24V applications where easy installation and safe backup power are required. The unit is designed for control and operation of smaller loads and comes with two 1.2 Ah batteries mounted in the housing. The battery backup has built-in charging, load output, potential-free alarm output and clear indication for normal operation, mains interruption/low battery voltage and triggered load protection. The power cut/low battery voltage function can be selected via jumper. The ECO 24V 1A Mini is mounted in a powder-coated metal cabinet and connects to 230 V AC via the supplied cable with plug

Enclosures

General assembly instructions

Mounting - wall mounting

  • Enclosure must be mounted vertically.

  • For good ventilation, at least 100 mm of free space should be provided above and on the sides of the enclosure. Do not block the flow of air on the sides

  • The device should be mounted at a comfortable working height, normally between 1.4 and 1.8 m.

  • Recommended distance between screw head and wall should be 1.5-2 mm.

  • Avoid placement in direct sunlight, near heat sources, or in environments with high humidity or dust.

  • Installation shall be carried out in accordance with the applicable installation rules and by a competent installer.

Appendix

Backup operating time on batteries

The reserve operating time in battery operation depends on how large a load is connected to the power supply. If the load varies, as with frequent opening of door locks, the time that batteries can continue to power the security system decreases. To get an estimate of reserve operating times see: www.milleteknik.se/Manualer/FaQ/Reservdrifttider/
