Product Description

OEP R35A03F panel mount Audio Transformer delivers professional-grade audio output with a maximum power rating of 12 W at 50 Hz. Designed primarily for use in high-fidelity audio circuits, this transformer features grain orientated silicon steel in the core, reducing distortion and stray magnetic fields to enhance audio clarity.

The transformer is a push-pull type with a 5k Ω centre tapped primary and secondary taps configured for 4 Ω and 8 Ω loads, making it ideal for use with ECL82 valves in audio amplifiers. It provides an inductance of approximately 16 H at 1 kHz which is critical for stable frequency response.

Constructed with an open frame and panel mount design, it offers convenient solder termination and is suitable for integration into various electronic chassis. The transformer is tested to withstand an isolation voltage of 2000 V, with hi-pot testing between primary and secondary windings at 1000 V RMS for 2 seconds, assuring robust electrical isolation.

Operational temperature range is from -20°C to 60°C, supporting use in varied environmental conditions. Its compact size (87.3 mm length, 52 mm width, and 49.5 mm depth) and weight (465 g) make it suitable for professional audio equipment where space efficiency matters.

This product is UL certified, complying with essential safety standards for electronic components. It is manufactured in the United Kingdom ensuring consistent quality in all units.

Provides high-fidelity audio output with low distortion. Durable panel mount design for secure installation. Multiple secondary taps for impedance flexibility. Excellent electrical isolation for safety and performance. Tested for reliable operation within wide temperature ranges.

Compact and lightweight form factor. UL approved for industrial and commercial use. Constructed with grain orientated silicon steel core. Suitable for professional and laboratory audio applications.
