IEC TR 62000:2021 provides guidelines concerning single-mode fibre inter-compatibility. A given category of single-mode fibre, for example B-655, can have different implementations by suitably optimising several of the following parameters: mode field diameter (hence effective area), chromatic dispersion coefficient, slope of the chromatic dispersion curve, cable cut-off wavelength. These…

IEC TS 63102:2021(E) highlights recommended technical methods of grid code compliance assessment for grid connection of wind and PV power plants as the basic components of grid connection evaluation. The electrical behaviour of wind and PV power plants in this technical specification includes frequency and voltage range, reactive power capability, control performance including active power based…

IEC 60601-2-41:2021 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of SURGICAL LUMINAIRES and LUMINAIRES FOR DIAGNOSIS, hereafter referred to as ME EQUIPMENT. If a clause or subclause is specifically intended to be applicable to ME EQUIPMENT only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies…

This edition includes the following significant technical changes with respect to the…

1 Scope This Standard specifies particular safety requirements for electronic controlgear for use on d.c. supplies up to 380 V and a.c. supplies up to 600 V at 50 Hz or 60 Hz and at an output frequency that can deviate from the supply frequency, associated with LED modules. Notes: 1) A lamp controlgear for LED modules may also be referred to as “LED controlgear”, “LED driver”, “LED power…

1 Scope 1.1 This Standard specifies general and safety requirements for a) non-integrated light-emitting diode (LED) modules (LEDni modules) and semi-integrated LED modules (LEDsi modules) for operation under constant voltage, constant current, or constant power; and b) integrated LED modules (LEDi modules) for use on dc supplies up to 250 V or ac supplies up to 600 V. LED modules within…
