Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz and 1,6 MHz to 30 MHz - Part 4-7: Portable low voltage decoupling filters - Safety requirements
This European product safety standard applies to the filter part of portable devices for household andsimilar uses (hereafter referred to as portable decoupling filters) consisting of the filter part, a plug or anappliance inlet or a provision for connection by terminals or with a non-rewirable cord and one (multiple) socket-outlet or an appliance outlet. They are intended for single-phase circuits for nominal currents not exceeding 16 A and for nominal voltages not exceeding 250 V a.c. to neutral operating in the frequency range 3 kHz to 148,5 kHz and from 1,6 MHz to 30 MHz.The filtering functions are described in EN 50065-4-1.This standard does not cover
