⚡ Function in the Electrical System

Traditional low-voltage intercom / video intercom system.
The Urmet 9000/230 transformer is installed on the power supply side of the system and provides 12 VAC to devices requiring a low-voltage source. It is specifically intended for powering call modules, illuminated nameplates, electric locks, porter switchboards and other compatible Urmet devices.
Urmet documentation also indicates that it can be used to power push-button modules and nameplates of the entrance panel when the required power exceeds that available from the main power supply.

🏭 Construction and Installation

The device is housed in an insulated enclosure for DIN rail mounting, with separate terminals for the 230 VAC primary circuit and the 12 VAC secondary circuit. The 3-module DIN configuration allows direct installation inside electrical panels and distribution boards.
The transformer can also be used to power multiple compatible loads within the intercom system, always respecting the maximum 18 VA power rating and the secondary current limits.

🛡️ Safety and Product Condition

New product, visually in good condition. The original packaging shows normal signs of storage and external wear, while the transformer appears intact in the photographs.
The self-resetting PTC protection operates in the event of secondary overload or short circuit. Urmet documentation specifies that, after a short circuit, the power supply must be interrupted for approximately 60 seconds to allow the voltage to reset.
⚠️ Connection to 230 VAC must be carried out exclusively by qualified personnel, respecting isolation, protection devices and applicable electrical regulations. The 12 VAC secondary output must not be confused with a 12 VDC output.
