WebMar 17, 2015 · The surge is called inrush current, the cold filament has a much lower resistance than the hot filament. This is why bulbs usually fail as they're turned on. The simplest solution might be to fit a regular light dimmer, and turn them up slowly. Or a suitably rated Negative Temperature Coefficient device could be used as an inrush … WebMay 4, 2024 · Internal (On-Board) Surge Protection Inrush Current Limiting Resistor - Power surges, and switching on power from AC mains in general, can allow inrush currents that can damage devices during the initial power-up phase. Inrush currents can be reduced and dampened with a fixed resistor.

Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on. Alternating-current electric motors and transformers may draw several times their normal full-load current when first energized, for a few cycles of the input waveform. Power converters also often have inrush currents much higher than their steady-state currents, due to the charging current of the input capacitance. The selection of … WebJan 26, 2015 · One aspect of ac motor protection is the surge-withstand capability of the motor itself.
