DOEPKE RK 24 zvončekový transformátor 2A/1,3A/0,6A 8V/12V/24V 09980654 (9980654)

The DOEPKE RK 24 bell transformer stands out with its multi-tap secondary, delivering 8V, 12V, or 24V AC from a single compact DIN-rail unit. Unlike fixed-output transformers, it adapts to different bell, chime, or signalling circuits without swapping hardware. The RK series is built for continuous duty in residential and commercial installations, with thermal overload protection and short-circuit resilience that keep call systems operational. Its 2-module width fits standard distribution boards, and screw terminals allow fast, secure wiring. Whether you are replacing an ageing transformer or planning a new doorbell system, this unit provides stable low-voltage power with minimal heat and noise.

Highlights

• Multi-voltage output: 8V AC (2A), 12V AC (1.3A), 24V AC (0.6A)
• Rated power 16 VA, suitable for continuous operation
• Thermal overload and short-circuit protection
• DIN rail mounting, only 2 modules wide (36 mm)
• IP20 protection, thermoplastic housing
• Meets EN 61558-2-8 safety standard

In daily use

Install the RK 24 on a standard 35 mm DIN rail in the distribution board. Connect the 230V AC primary to a dedicated circuit breaker, then choose the secondary tap that matches your bell or chime voltage. The transformer runs silently and stays cool even under sustained load, thanks to its efficient core and thermal protection. For larger installations, multiple units can be mounted side by side without derating. The screw terminals accept solid or stranded conductors up to 2.5 mm², making wiring straightforward for any electrician.
