Description

The ST312 is a 25VA safety transformer providing a 230V AC input with 12V or 24V AC output for use with low-voltage safety circuits, SELV systems, and other applications requiring electrically isolated extra-low voltage supplies. It conforms to the requirements for safety transformers under EN 61558.
DIN rail mounted and suitable for installation within standard distribution boards. The 25VA output is appropriate for powering door access systems, nurse call systems, CCTV power supplies, or other safety extra-low voltage control circuits.
Part of Hager’s modular transformer range, the ST312 is complemented by larger safety transformers including the ST315 (63VA) for more demanding SELV applications.
