Low Voltage Lighting Systems

IEC 60364-7-715 Extra Low Voltage (ELV) Installation Regime

Used in store track spotlights, pool surrounds, and architectural facades. Are lights under 50V harmless? Have you ever considered the overcurrent risk (cable melting) that low voltage can cause?

Danger of increasing current load as voltage decreases.

12V or 24V systems (ELV/SELV) are frequently preferred for decorative purposes because they reduce the risk of electric shock to zero. However, the basic engineering principle (P=V*I) applies: the lower the voltage, the higher the amperage that passes through the cable to transmit that power.

12V cables that are not selected with the required thickness will quickly melt and ignite in concealed suspended ceilings, turning red like a pomegranate. AES analyzes this fine line with transformer (driver) thermal load testing, thus documenting the safe operation of the systems.

ELV Lighting Thermal Analysis

Our Radar for Extra Low Voltage Systems:

  • Cable Cross-Section / Current Carrying Analysis:
    If a 12V LED line carries 40 Amperes of current, it is calculated whether the cross-section of the LED is sufficient to carry this current without causing a fire.
  • Short Circuit Protection Reactant:
    This eliminates the risk of not being able to detect a short circuit due to the decreasing voltage at the secondary output of the transformer (driver) as the distance increases.
  • Driver Heat Absorption:
    The danger posed by transformers, especially those tightly packed into suspended ceilings without ventilation gaps, is monitored using thermal cameras.

Abandon the Wrong Transformer

Ambient lighting, the heart of architectural projects, is often designed by interior designers, but the thermodynamic/operational risks of this lighting can only be integrated into commercial use with AES Innovation's technical standard approval.

Frequently Asked Questions

Frequently asked questions about low-voltage systems.

The electric shock threshold for the human body is generally above 50V AC, 120V DC. So it won't shock you directly, but the resulting fire is dangerous.

Yes, in SELV systems, but only if the insulation/short circuit minimum distance standards (7-715) are met for pendant lamp wires.
