Upowertek Released Low Inrush Current LED Driver
Recently, Upowertek released 200-400 W low inrush current LED drivers. With the new design, less MCBs (miniature circuit breaker) will be used when doing luminaire installation, which can make field-wiring easier and cost-saving. For driver solution with less than 200 W, an external solution of…
The high inrush current on switching LED power supplies has become an area of concern in the lighting industry. It refers to the input current of a tiny duration that flows into the LED driver which can be regarded as a capacitive device during the power on stage. The figure below shows the typical inrush current with capacitive load from 230 Vac 50 Hz AC line input. If there are multiple LED Luminaires powered on at the same moment, the max peak inrush current and its duration might trigger the MCB.
The new feature is achieved by reducing the peak inrush current (Ipeak) to a very low level and increase the duration.
