Everything you need to know about Extra-Low Voltage (ELV) Systems

What are Extra-Low Voltage Systems (ELV)? Extra-Low Voltage means the voltage of electricity supply is in a range that is low enough that it does not carry any high risk of any high voltage electrical shock(s). The range of voltage that can be classified as Extra-Low Voltage is alternating current not exceeding 50 V AC and direct current not exceeding 120 V DC (ripple free). This is based on the standards as per EN 61558 or BS 7671. Therefore, Extra-Low Voltage S... Read More
