The ASB 116 starting current limiter is used in conjunction with AC electric motors and power tools that start in no-load operation. This electronic current limiter prevents the house circuit breaker in the mains connection box from being tripped by high inrush currents. The starting current limiter is also suitable for capacitor motors, large transformers as well as halogen lamps.
Not suitable for compressors, high-pressure cleaners and other devices that start under load. The ASB cannot be used on inverters and current generators, since current limitation does not take place during load changes, nor is the continuous current limited.
The ASB is only suitable for operation on the public power supply. The use of the ASB is quite simple. Instead of the power tool, the ASB is plugged into the socket and the tool - possibly via an extension cable - is plugged into the ASB. The ASB is immediately ready for operation, there are no settings to be made, there are not even elements for operation. Now start the power tool at idle and, ideally, you will not notice that the ASB limits the inrush current. The moment the motor of your tool has started, you can immediately start working: push the wooden board through the circular saw, plunge the Flex into the stone or feed the shredder with garden material.
There is only one thing you should watch out for: Allow the ASB some time to cool down and do not switch the tool on and off several times a minute. If this cannot be avoided, limit the switch-ons to about 60 per hour, because the parts for the limits in the ASB get very hot.

- How exactly does this work with the ASB?
Electric motors make an axis rotate with magnetic fields. The magnetic field is generated with copper coils when current flows through the wire. Before the magnetic field has been established after switching on, the copper wire "looks" like a short circuit to the fuse. It almost is one, after all, there is a conductive connection between the two terminals and the fuse "flies out" because enormous currents flow in that brief moment, see the tripping diagram. The ASB connects a power resistor in front of the copper coil, which "consumes" the excess current as heat in a flash and thus limits the current. After 0.7 seconds, the magnetic field has long since built up, the motor turns and consumes the current itself, and only then does a relay in parallel with the power resistor switch the power supply fully on. The ASB itself has only the function of a normal line when the machine is running and the power resistor can cool down again.

- My compressor has only 2000 watts. Why does not this even work with the ASB 120?
Electric motors that start at idle draw a very high current for a very short time when they are switched on. If this is limited by the ASB, the motor starts anyway. If the motor starts under load because it has to move the pistons of the compressor against the pressure in the boiler, it cannot start with the limited current. If the ASB now switches on fully after 0.7 seconds, the full starting current is still drawn. The limitation had no effect and the fuse "blows". The ASB does not help here.
-
- My inverter brings 2300 watts, the Flex needs only 1000 watts. Why should that not work with the ASB?
An inverter turns a DC voltage, e.g. a 12-volt car battery, into an AC voltage of 230 volts and can supply about 10 amps at the rated power. An electronic system regulates current and voltage, the regulation takes a certain amount of time and this is not available for the rapid load change. At the moment of switching on, the ASB limits the high starting current, but it switches on fully after 0.7 seconds and a lot of current is still needed quickly. Since no inverter has large capacitors that could supply large currents very quickly and the connected car battery is too sluggish, the voltage at the inverter collapses. Either the fuse on the inverter "blows" or the internal protective circuits simply switch off the inverter.

- Does an ABS 120 work with an inverter generator?
Yes - if the inverter is a pure sine wave inverter.
No, if the inverter has a square wave output.
