Door entry system power supply 18A2

Intercom Power Supply – the Reliable Heart of Your System

This power supply, dedicated to intercom systems from MIWI-URMET, is a key element ensuring stable and trouble-free operation of the entire system. Designed to work with MIWI, MIWUS (model 1127) panels, and panels equipped with MR2 (model 725) and 1128/501 (Genya, Smyle, Aura) call modules, it provides a universal solution for various installations. The power supply operates in a "4+n" system, meaning it can support multiple subscribers.

Functionality and Safety in One Device

The power supply is equipped with a built-in triac, which allows control of the electric strike, eliminating the risk of voltage drop when opening the door. Additionally, it has overload protection in the form of a T100mA fuse, protecting the installation from damage. A dual-tone call generator allows simultaneous notification of one or two users. The device is designed for DIN rail mounting, making installation and servicing easier.

The power supply provides a stable output voltage of 12V AC with a maximum load of 500mA. It operates with a supply voltage of 230V AC @ 50Hz and is characterized by a power of 10VA. The minimum load resistance of the generator is ≥ 12.5Ω. The device is designed to operate at temperatures from 0°C to +45°C. Its compact dimensions (106 x 90 x 66mm) allow for easy integration into existing infrastructure.

Good to know: The built-in triac allows smooth and reliable control of the electric strike, and thermal protection protects the power supply from overheating and damage. This ensures long-term and trouble-free operation of the intercom system.
