Extra low voltage (ELV) means voltage of 50V or less (AC RMS), or 120V or less (ripple-free DC). Low voltage (LV) means voltage greater than ELV, but not more than 1000V (AC RMS) or 1500V (ripple-free DC). High voltage (HV) means voltage greater than low voltage.
ELV Systems. ELV (Extra-Low Voltage) systems require low electricity supply voltage to operate, with low risk of electrical shock.
ELV covers all the new modern technologies that are increasingly becoming must-have systems in every building such as data network, CCTV, fire alarm systems, public address systems, audio/video solutions, access control and intrusion detection systems, home automation, and much more!
