inrush current

listen to the pronunciation of inrush current
English - Turkish
(Elektrik, Elektronik) ani akım
(Elektrik, Elektronik) Ani akım: Cihazların çalıştırılmaları esnasında çok kısa süre içinde beslemeden çektikleri yüksek akım. Normal çalışma durumlarda çektikleri akımdan bir kaç kat büyüktür
English - English
The ac input current as measured during the initial turn-on of the power supply This current reduces to a lower steady-state current once the input capacitors charge
The maximum, instantaneous input current drawn by a power converter at turn on Also called input surge current (Typically the charging current of the input capacitance )
Inrush current is the initial surge of current that results when power is first applied to a load having a low starting impedance, such as a discharged capacitor, a cold lamp filament, or a stopped motor's winding
Starting any electronic product generates a momentarily high input current surge, which is called inrush current High inrush current can cause problems with certain types of switch gear SuperDimTM DIGITAL dimming ballasts have low inrush current
The initial surge of current required by a load before resistance or impedance increases to its normal operating value
– Maximum, instantaneous input current drawn by a power supply at turn on Also called Input Surge Current
Maximum allowed rate of change of quiescent current after a device powers up (non-transmitting) It should not exceed 1 0 mA/msec after the first 20msec of connecting a device to a network or after 20 msec after applying power to the network See Maximum Current,Lift Off Voltage top

The initial high peak of current during the first few cycles of energization which can be 30 to 40 times the rated current
the peak instantaneous input current drawn by a power supply when it is initially turned on
The initial momentary surge current demand before a load resistance of impedance increases to its normal operating value
An abnormally high current which is occasionally drawn when a transformer is first energized, due to residual flux in the core
The peak instantaneous input current drawn at turn on by a power supply
The initial large current demand needed to start up certain types of electrical equipment, like motors, before their resistance or impedance increases to their normal operating value
The peak current drawn by a device upon first application of the supply voltage, usually the result of transformer magnetizing current or the charging of input filter capacitors Some converters feature circuits which will reduce inrush current, thus eliminating nuisance tripping of input circuit breakers
Inrush current is the current a Power over LAN Enabled device requires to startup Normally, it is higher than the normal operation current This current converges to a nominal continuous level once the load input capacitance is fully charged
The current surge generated when a piece of equipment such as a servoamplifier is connected to an AC line This surge is typically due to the impulse charging of a large capacitor located in the equipment
Measurement of the initial current flow in Capacitive or Lamp applications Inrush currents can be as much as 15 times the rated current flow of the application
A brief and momentary surge of current through the transformer, due to residual flux, experienced at the instant the transformer is energized
