Extra-low voltage: Music, Standards, Art & Measurement

Extra-low voltage (ELV) is an electricity supply voltage and is a part of the low-voltage band in a range which carries a low risk of dangerous electrical shock. There are various standards that define extra-low voltage. The International Electrotechnical Commission (IEC) in IEC 61140 define an ELV device or circuit as one in which the electrical…
