1 Phase Start-up Current Limiter
According to IEC60947-4-2, DIN/EN60947, VDE0660
PCB version
Mod.No. 8700.0040
K700 with integrated start-up current limiter
Mod.No. 0098.7770
Aluminium case with integrated start-up current limiter
Mod.No. 0098.7775 - Schuko
Mod.No. 0098.7773 - CEE
Mod.No. 0098.7774 - Switzerland
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:
This start-up current limiter 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.
It is possible that drives with heavy start-up or motores with low torque (e.g. compressors, coagulants, pumps) can't be start with start-up current limiters (under inappropriate conditions). The reason for this is that the motor can't induce enough torque during the start-up in case of the volitional limitation of the start-up current. Electronic motors and collector motors can't be startet either.

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).
