Product Description

ABB 2CSM228785R0802 TM40/24 bell transformer is a DIN rail mounted device designed to step down mains voltage from 230 V AC to a stable 24 V AC output with a power rating of 40 W. It provides safe and reliable operation through double isolation between primary and secondary windings and features a fail-safe bell transformer design that protects against overloads and short-circuits by ceasing operation when faults occur.

The transformer features a compact footprint with dimensions of 85 mm length, 52.5 mm width, and 65 mm depth, making it convenient for installation in industrial control panels, electronics, and electrical distribution systems.

Equipped with class B insulation rated for operation up to 130°C and an IP20 finger-safe casing, the unit offers protection against solid objects larger than 12 mm, ensuring safety in various installation environments. It operates efficiently between 50 Hz and 60 Hz frequency ranges and accepts screw-type terminations for secure wiring connections.

Applications of this bell transformer include doorbell circuits, HVAC system controls, and medical device power supplies where a low-power, secure voltage conversion is essential. Its fail-safe modular transformer type ensures operational reliability by preventing electric shocks and faults in industrial and commercial settings.

Compact DIN rail mounting design simplifies installation. Double isolation between windings enhances safety. Class B insulation enables operation in harsh temperature conditions. Built-in SELV circuit provides earthing protection.

IP20 finger-safe housing protects against accidental contact. 5 outputs with screw terminations ensure reliable wiring. Temperature operating range from 10°C to 40°C. Suitable for powering doorbells, HVAC systems, and medical devices.

The model TM series 2CSM228785R0802 TM40/24 is trusted in electrical automation, building installations, and other commercial power supply applications. Explore more Transformers and electrical components in the Electronics & Electricals category at EnvMart for comprehensive industrial solutions.
