RS PRO PCB Transformer 2 x 15 V AC, 2 Output, 30 VA, 230 V/115 V Input, Low Profile, 121-3856

RS PRO 121-3856 PCB Transformer is engineered for modern electronic assemblies requiring robust AC power conversion directly on the circuit board. With dual 15 V AC outputs and a total power rating of 30 VA, this low-profile transformer delivers consistent performance and efficient operation for sensitive or high-demand loads.

Supporting a choice of 115 V or 230 V AC primary supply, it caters to international use and adaptable product designs. The independent secondary windings provide flexibility - either series or parallel - for tailored voltage and current output, enabling integration in control panels, instrumentation, or power management in embedded systems.

With a winding type designed for low interwinding capacity and reduced noise, the transformer ensures clean power delivery and minimized electromagnetic interference. Safety is further supported by its 3.75 kVrms isolation voltage and construction compliant with key standards such as CE, RoHS, and IEC/ASNZS 61558 certifications.

Low profile transformer, just 68 mm x 57 mm x 35 mm, fits space-constrained PCBs. Supports two outputs for multi-circuit powering on a single PCB. PCB mounting and 20 pins promote safe, robust installation. Maximum ambient temperature of 130°C suits demanding environments.

Electrical and flash tested for consistent quality and safety. High efficiency with low temperature rise and radiated noise. Meets international approvals for global deployment. Ideal for industrial automation, instrumentation, HVAC control, and compact power solutions; commonly used in manufacturing, laboratory devices, and commercial electronics.
