Safety transformer 230/12-24VAC 16VA ST313

Safety transformer – reliable protection and flexible power supply

This Hager safety transformer is a compact and efficient solution for reducing the mains voltage from 230V to safe values of 12V or 24V AC. Designed for a wide range of applications, it works perfectly in both home and industrial installations, providing stable and safe power for various devices. Its modular design simplifies mounting on a DIN rail, and high-quality workmanship guarantees long-lasting and trouble-free operation.

Construction and application

The ST313 transformer is designed for galvanic isolation of circuits and voltage reduction. This protects users from electric shock and safeguards connected devices from overvoltage. The ability to choose the output voltage (12V or 24V) increases its versatility. It is ideal for powering alarm systems, home automation, low-voltage lighting, as well as controllers and other devices requiring safe power. Its compact dimensions (70 mm wide, 58 mm deep and 85 mm high) allow for easy integration even in limited space.

Key features and benefits

• Output voltage versatility: The ability to choose between 12V and 24V AC allows you to adapt the transformer to different needs without having to purchase multiple devices.
• Safety: Provides galvanic isolation, protecting against electric shock and damage to connected devices. It has built-in short-circuit and thermal protection, which further increases the level of safety.
• Modular design: Allows for easy mounting on a DIN rail, saving time and space in the distribution board. A width of 4 modules ensures compatibility with most standard systems.
• High efficiency: Maximum output power of 16VA allows you to power many devices with low power consumption. Low power loss (maximum 1.5W) translates to energy savings.
• Durable construction: Made of high-quality materials, which guarantees reliable operation for a long time. Complies with EN 61558-2-6 standard confirming its compliance with European safety standards.
• Overload protection: Built-in short-circuit protection protects the circuit from damage in the event of a short circuit - like most circuit breakers in this class.
• Secondary current adapted to needs: Available output currents of 1.33A for 12V and 0.67A for 24V allow for optimal adaptation to the requirements of specific applications.

The primary voltage is 230 V, and the secondary voltage can be set to 12 V or 24 V AC. The maximum output power of the transformer is 16 VA (16 W), with a secondary current of 1.33 A for 12 V and 0.67 A for 24 V, respectively. Its dimensions are: width 70 mm, height 85 mm and depth 58 mm.

The ST313 transformer is a solid choice for professionals and end-users looking for a reliable and safe solution for reducing voltage in various electrical applications. Its versatility, durability and high quality workmanship make it an ideal element of any electrical installation.
