PELV (English for “Protective Extra Low Voltage” – formerly also known as safety extra-low voltage; see also SELV) describes a voltage that is set so low(extra-low voltage) that there is no danger from body currents in the event of indirect contact or direct contact that does not cover a large area. If insulation fails, there […]
SELV (Safety Extra Low Voltage) describes a voltage that is set so low that there is no danger from excessive body currents when touching it directly, either during normal operation or in the event of a single fault. If insulation fails, there must still be sufficient protection. In the case of power supply units, this […]
