Product Description

The RS PRO 504-476 PCB Transformer is a high-quality step-down transformer designed for mounting in electronic circuit boards, ideal for industrial, commercial, and laboratory applications requiring isolated AC voltage conversion. This transformer enables flexible distribution of electrical power in complex PCB designs where reliable, dual-output AC supplies are essential.

The transformer features a 230 V AC primary winding and two independent secondary outputs ranging from 5 to 24 V AC, delivering up to 12 VA of power. Its through hole mount design ensures robust placement and stable electrical contact on PCBs, while extra pins further secure the transformer during board assembly. The double-section metric bobbin construction and full varnish impregnation enhance mechanical integrity, contribute to electrical insulation, and allow for higher operational reliability.

Safety and compliance are central to the RS PRO 504-476's design. The unit is tested to meet BS3535 and EN 60742 standards, as well as AS/NZS 61558.2.6, CE, IEC/BS/EN 61558-1, and RoHS directives. An insulation voltage of 4 kVrms helps protect sensitive electronics and ensures safe operation under demanding conditions. Fully shrouded bobbins reduce risk of accidental contact, and the transformer is both electrical and flash tested for maximum safety.

The compact dimensions (38 mm length, 35 mm width, 30 mm depth), along with a gross weight of 400 g, allow for efficient integration into space-restricted PCBs and enable use in environments where size and weight are critical factors. The transformer operates at frequencies of 50 to 60 Hz and withstands maximum operating temperatures up to 130°C, extending its usability across diverse settings such as industrial automation, instrumentation panels, laboratory power supplies, and commercial electronics.

Key features include dual independent outputs for configurable voltage and current arrangements, secure through-hole mounting, high insulation voltage, and adherence to major international safety standards. Typical industrial use cases are industrial control systems, power supply circuits, laboratory equipment requiring AC isolation, and custom electronics projects demanding reliable PCB-level voltage transformation.
