Overview
EN 61050:1992 (CLC) - titled "Transformers for tubular discharge lamps having a no‑load output voltage exceeding 1 kV (generally called neon‑transformers) - General and safety requirements" - specifies general and safety requirements for neon transformers. It applies to independent and built‑in single‑phase transformers with separate input and output windings, intended for use on AC supplies up to 1000 V at 50 Hz or 60 Hz, and for supplying/stabilizing cold‑cathode tubular lamps with no‑load output voltages > 1 kV and ≤ 10 kV. The EN text corresponds to IEC 61050:1991 with Corrigendum 1992.
Key topics and requirements
The standard focuses on safe design and use of tubular discharge lamp transformers (neon transformers) and typically addresses the following technical areas:
- Scope and ratings - intended supply voltage, frequency, and permissible no‑load output voltage range (1 kV–10 kV).
- Design and construction - requirements for independent and built‑in single‑phase types with separate primary and secondary windings.
- Electrical safety - measures to protect against electric shock and hazards related to high no‑load voltages associated with neon transformers.
- Performance and stability - ensuring transformers supply and stabilize cold‑cathode tubular lamps reliably for lighting, advertising signs, and light signals.
- Marking and information - identification, rated voltages, frequency, intended application and any essential installation instructions.
- Compatibility with mains - suitable for AC supplies up to 1000 V at 50/60 Hz.
- Reference to IEC - harmonization with IEC 61050:1991 (plus Corrigendum 1992).
(Note: this summary highlights the standard’s subject matter. For precise test procedures, limits and clauses consult the full EN 61050 text.)
Applications and users
EN 61050 is relevant to professionals and organizations involved with neon lighting and signage:
- Manufacturers of neon-transformers and tubular discharge lamp assemblies
- Designers and installers of electric advertising signs, shopfront illumination and light signals
- Safety and compliance engineers verifying electrical safety and product marking for high-voltage lamp transformers
- Test laboratories and certification bodies referencing CLC/EN/IEC standards
Related standards
- IEC 61050:1991 (base document) - EN 61050 reproduces and adapts this for European/CENELEC use.
- Other EN/IEC standards on transformers, insulation and electrical safety may be consulted for complementary test methods and requirements.
