Product information

Description

The Hager ST314 safety transformer is a robust electrical component engineered for secure power conversion within electrical distribution boards and enclosures. It efficiently transforms a standard 230 V AC mains input into selectable low-voltage outputs of 12 V or 24 V AC, offering a total power capacity of 40 VA. Designed for durability and safety, this transformer ensures stable operation for various low-voltage applications in both residential and industrial environments.

Advantages

This safety transformer provides reliable galvanic isolation between the primary and secondary circuits, which is essential for protecting sensitive control equipment and users. Its compact design allows for seamless integration into standard DIN-rail mounted systems, saving valuable space in electrical cabinets. The dual-voltage output capability offers flexibility for different signaling or control requirements, while the high build quality ensures long-term operational stability under continuous load conditions.

Suitable for

Powering doorbells and intercom systems
Operating low-voltage control relays and contactors
Supplying power to signaling and alarm indicators
Supporting auxiliary low-voltage automation equipment

When it may not be suitable

This transformer is not intended for high-power applications exceeding its 40 VA rating, as overloading may lead to thermal protection activation or component failure. It is also not suitable for DC-powered devices, as it provides an AC output only.

Key specifications

Input voltage: 230 V AC
Output voltage: 12 V or 24 V AC
Power rating: 40 VA
Mounting type: DIN-rail
Frequency: 50/60 Hz

How to use

The Hager ST314 should be installed by a qualified electrician within a suitable electrical enclosure. Ensure the input cables are connected to the 230 V supply terminals and the output cables are connected to the secondary terminals corresponding to the desired 12 V or 24 V output. Verify that the total load of the connected devices does not exceed the 40 VA limit before energizing the circuit.

What to consider before purchase

Verify the voltage requirements of your low-voltage equipment
Ensure the total power consumption of connected devices is below 40 VA
Check available space in your electrical distribution board
Confirm compatibility with your existing DIN-rail mounting system

Usage recommendations

Always ensure that the transformer is installed in a well-ventilated enclosure to prevent heat buildup and follow all local electrical safety regulations during installation and maintenance.
