Fuse module LB4/1.0A/PTC AWZ575

Fuse module for alarm and CCTV systems

This fuse module, catalog number AWZ575, is an indispensable element in low-voltage power systems. Designed to distribute power in alarm systems and CCTV (closed-circuit television), it provides independent protection for four output circuits. This means that a failure of one connected device does not affect the operation of the others. The module accepts a supply voltage in the range of 10-30V DC, making it compatible with a wide range of power supplies.

Construction and functionality

The AWZ575 module offers two ways to connect the power supply: via a screw terminal or a DC 5.5/2.1 mm socket. Each of the four AUX1-AUX4 outputs is protected by a 1A PTC polymer fuse. If a fuse blows, the LED assigned to that circuit informs you – it goes out, indicating the need to check the load. Additional overvoltage protection is provided by varistors, protecting both the module itself and the connected devices. This comprehensive approach to safety makes the module ideal for applications requiring high reliability.

Installation and technical specifications

The module is easy and convenient to install – it can be mounted with mounting tape or screws (mounting holes with a diameter of 3mm). Compact dimensions (80 x 43 x 21 mm) allow installation even in limited space. The module operates in a wide temperature range (from -10°C to +50°C) and meets the requirements of environmental class II. Current consumption is in the range of 5-30 mA at an input voltage of 10-30V DC. The net weight of the device is only 39g, which facilitates its transport and installation.
