The IEC defines three types of extralowvoltage systems (FELV, PELV, and SELV), which are distinguished by their successively more restrictive safety properties. 2. SELV system is an electrical system in which the voltage cannot exceed ELV under normal conditions. SELV stands for separated extralow voltage.Jul 01, 2014 What is Separated Extra Low Voltage (SELV) The design involves using an insulation transformer, guaranteed minimum distances between conductors and insulation barriers. The SELV systems must have protectiveseparation such as reinforced insulation, double insulation or protective screening from all circuits carrying higher voltages. extra low voltage system design

Extralow voltage. Some types of landscape lighting use SELV PELV (extralow voltage) systems. Modern battery operated hand tools fall in the SELV category. In more arduous conditions 25 volts RMS alternating current 60 volts (ripplefree) direct current can be specified to further reduce hazard.
