Special features:
- Continuously variable current limit and start-up time
- Bypass relay for lossless operation
- Soft start, even when mains current is already applied (load detection)
- Best protection against triggering circuit breaker during start-up
- Automatic load detection
For use in:
- Machines with asynchronous motors, e.g. saws, chippers, stone cutting machines etc.
Please note:
The start-up current limiter type 16-40A limits the current through reducing the output-voltage. Therefore it is not possible to connect a control electronic or electromagnetec components to the load side.
Drives with heavy starting or motors with low torque (e.g. compressors, blowers, pumps, motors and partiylly collector motors) can't be start with start-up current limiters under inappropriate conditions. This is because that the motor can't induce enough torque during the start-up in case of the volitional limitation of the start-up current.
For these critical cases we also developed the type "Spg.-steller". This allows a much higher output voltage, so that the most critical applications also can be started. Depending on the ohmic resistance of the load it will be higher starting currents. The current peak by starting is prevented, so that the fuse does not blow. But it is necessary that the power supply as e.g. a power unit supplies a high enough current, that the motor can create enough torque to have the possibility to start.

Functional description:
The KLIBO 1 phase start-up current limiter is installed between the mains connection and the consumer. The control unit detects when the consumer is switched on and limits the start-up current to a set value, making the start-up smooth and protecting the drive. The current limit is adjustable and can be set to a value that will not trigger the circuit breaker.
The load detection is another feature highlight of this start-up current limiter. Many commercially available start-up current limiters only work for the first start-up when the consumer is plugged in or switched on. This causes problems when the device is installed between the mains connection and the consumer. When the motor is started for the second time, the soft start device has already been activated and does not limit the start-up current anymore. The motor will start with approximately 4 to 6 times its nominal current. This will not happen with our 1 phase start-up current limiter. It detects that the motor is switched on again, and thus can limit the start-up current every time the motor is started.
After start-up the KLIBO 1 phase start-up current limiter works virtually without loss and interference (no EMC interference).
