Fuse module LB8/1.0A/PTC AWZ579

Fuse module for alarm and CCTV systems

This fuse module, catalog number AWZ579, is a reliable solution for power distribution in low-voltage alarm systems and CCTV monitoring installations. It allows for safe and efficient power supply to up to eight devices from a single source. Designed to operate in the voltage range of 10-30V DC, it offers connection flexibility thanks to two power inputs – a screw terminal and a popular DC 5.5/2.1 jack.

Construction and functionality

The AWZ579 module is equipped with eight independently protected power outputs, each protected by a 1A PTC polymer fuse. This is crucial for ensuring stable operation of connected devices and protecting against short circuits or overloads. If a fuse trips, an LED assigned to that circuit informs you – quick problem identification saves time during servicing. Additional varistors on each output protect both the power supply and connected receivers from overvoltage, increasing the reliability of the entire system.

Installation and application

Module installation is simple and intuitive – it can be mounted using a mounting rail or self-adhesive tape. Compact dimensions (124 x 43 x 21 mm) allow for installation in limited space. This module is perfect for rack cabinets, power supply enclosures or directly at devices requiring power. The ability to mount on PSD (desktop) series power supplies further increases its versatility. Thanks to SCP (short-circuit protection), OLP (overload protection) and overvoltage protection, the module provides comprehensive installation protection.
