Ntc inrush current limiters

Web11 feb. 2015 · On the incoming power we have an Inrush Current Limiter to limit the draw on start-up from capacitors charging. I evaluate returns on these motors and have seen these current limiters cracked or crumbling , but there's no evidence of a short on the board. I'm having a hard time finding information of failure modes/causes for these. WebWhen mounting NTC thermistors you have to ensure that there is an adequate distance between the thermistor and all parts which are sensitive to heat or combustible.

Web4 sep. 2024 · Figure 2: Typical characteristic curves of EPCOS NTC ICLs. Right: NTC inrush current limiter with a starting resistance R 25 of 10 Ω. Selection criteria for NTC ICLs. The two most important criteria for determining the suitable NTC thermistor are the initial resistance (R 25) and the maximum current. First, the required R 25 is determined. WebVNTC Voltage drop across the NTC under test [V] The capacitor Ctest is discharged via the series resistor RS and the NTC inrush current limiter. The load voltage is chosen such that the voltage applied to the thermistor at the start of discharge is VNTC = 375 V (corresponds to (230 V + ∆V) 2).
