ABB 10W Bell Transformer, CE, 230V Primary, 4 → 12V ac Secondary | 2CSM228715R0802 TM10/12

Try this DIN rail bell transformer from ABB to safely step down primary voltages of 230V AC from a mains supply. It outputs secondary voltages of 4, 8 and 12V AC so it’s suitable for use with a discontinuous load like a doorbell that you use intermittently. As this is a fail-safe transformer, you can trust it’s a safe option as it won’t function in overload or short-circuit conditions. Double insulation between its primary and secondary windings indicates effective electrical isolation so there’s little risk you’ll make accidental contact with harmful high voltages. This unit also offers a SELV circuit that provides grounding as a further safety precaution.

• Label space on consumer unit helps with organisation
• Class B insulator, so has a maximum allowable temperature of +130°C for use in harsh environments
• Compact dimensions of 85 (H) x 36 (W) x 65mm (D) make it easy to fit into a crowded board
• DIN rail mounting style for fast, tool-free installation onto a standard 35mm DIN rail

• Medical devices
• HVAC systems
• Process control

This unit is IP20 rated, so it’s finger-safe and protected against objects larger than 12mm.
