## Summary description

Laskomex TR/B 2303 is a mains power transformer with built-in thermal fuse, rated 25 VA and providing dual low-voltage outputs of 12 V and 14 V. Designed for powering small electronic devices, control panels or security systems, it converts mains voltage to stabilized secondary voltages and includes thermal protection against overheating. Suitable for mounting in enclosures and distribution boxes.

## Long description

Laskomex TR/B 2303 is a mains power transformer with integrated thermal fuse, rated 25 VA and offering two low-voltage secondary outputs: 12 V and 14 V. Intended for use in small electronic devices, control panels and security systems, this transformer converts standard mains voltage to safe low-voltage supplies while providing built-in thermal protection to reduce the risk of overheating. It is suitable for mounting inside enclosures and distribution boxes where a compact, reliable transformer is required.
Advantages
The transformer provides dual voltage outputs (12 V and 14 V) from a single compact 25 VA unit, allowing flexible use across different low-voltage circuits. Its integrated thermal fuse offers automatic protection in case of excessive temperature, simplifying installation by avoiding an external thermal safeguard. The design is compatible with enclosure and distribution box mounting and is intended for continuous operation within the specified load, ensuring predictable performance for small installations.
Suitable for
Powering small electronic devices and modules
Supply for control panels and automation components
Low-voltage circuits in security and alarm systems
Installation inside distribution boxes and enclosures
Key specifications
Rated power: 25 VA
Secondary outputs: dual low-voltage outputs — 12 V and 14 V
Built-in thermal fuse for overtemperature protection
Designed for mounting in enclosures or distribution panels
Primary: mains voltage input suitable for standard supply (observe local mains rating)
Intended for continuous operation within rated power and temperature limits
How to use
Mount the transformer securely inside the chosen enclosure or distribution box, ensuring adequate clearance for ventilation and access to connection terminals. Connect the primary winding to the mains supply in accordance with local electrical regulations and wiring practices, and connect the secondary outputs to the low-voltage circuits requiring 12 V and 14 V. Verify that the total load on the secondary outputs does not exceed the 25 VA rating and that wiring and connectors are rated for the expected current. If the built-in thermal fuse activates, disconnect mains power and inspect the installation for overload or ventilation issues before replacing or repairing.
Usage recommendations
Use the transformer within its rated 25 VA capacity and provide adequate ventilation to prevent nuisance activation of the thermal fuse. Ensure installations are performed by qualified personnel and that wiring follows local electrical codes. For combined loads on both outputs, calculate the summed power to keep within the transformer's rating and avoid prolonged operation near maximum load.
