Safety transformer 230/12-24VAC 40VA ST314
Safety transformer – reliable power in your circuit
This Hager safety transformer is a key element of electrical installation, providing safe and stable power to low-voltage devices. Designed for surface mounting, it is ideal for both home and industrial installations. Its modular design makes it easy to integrate with existing systems.
The transformer offers two outputs – 12V and 24V AC – making it a versatile solution for various applications. Short-circuit protection and thermal protection guarantee long-lasting and trouble-free operation. Compact dimensions (70 mm wide, 58 mm high and 85 mm long) allow for easy installation even in limited space. It occupies 4 modules on a DIN rail.
Key features and applications
- Versatility: Two output voltages (12V and 24V AC) allow you to power a wide range of devices, from doorbells and alarm systems to emergency lighting and controllers.
- Safety: Built-in short-circuit and thermal protection protects both the transformer and connected devices from damage.
- Modular design: Allows easy integration with existing electrical panels.
- Compact dimensions: Allow installation in tight spaces.
- 40VA power: Provides sufficient power for most common applications.
- Secondary side current: 3.33A at 12V and 1.67A at 24V – allows you to select the appropriate load for the transformer.
- Application: Ideal for powering security systems, home automation, low-voltage lighting and other devices requiring a stable 12V or 24V AC voltage.
Thanks to its high-quality workmanship and compliance with safety standards, the Hager ST314 transformer is an investment in reliability and peace of mind. It is a solid solution for both professional installers and end-users looking for a safe and efficient low-voltage power source.
