- Order number: EFD1000009
NTC - Inrush current limiter
1 ohm for 16 A ! 250V AC
perfect for power amps over 1 kW
22 ohms for 2 - 4 A, 250V AC
perfect for 13V / 20A transceiver power supply
Suggested installation for the new inrush current limitation:
The easy installation of this new component - a temperature dependent resistor - can be made anywhere between the 220V - 240 V AC socket and the primary side of the transformer or the motor.
The resistor is simply connected in series with the "on" switch or fuse. When installing, be aware that the resistor can become ca. 100 °C hot. A distance of more than 2 cm from other components is advantageous for good functioning.
In the warm state of the current limit (approx. 80 °C), the value of the series resistor is less than 0.01 ohms, so that the voltage drop / loss has virtually no impact. A series circuit of these useful components is also possible.
