The SKP-BC40 power supply monitors whether the torque-off setting on the electric screwdriver is reached within an adjustable time window. This detects errors such as incorrect screws (too long/too short), stripped screws, jammed screws, or missing screws. Errors are prevented, thereby improving product quality. The user has five freely programmable programs at their disposal. All functions can be disabled or locked via a key switch. Each OK screw connection is counted and compared to a target count. OK, NOK, and total OK counts are displayed via visual and audible indicators. The speed is adjustable in two stages. A soft start ramp facilitates finding the first threads and is continuously adjustable up to 5.0 seconds. The auto-learning function allows the control unit to be easily programmed for the specific fastening application. - Counting function and fastening time monitoring - Control unit for the complete brushless screwdriver series from 0.02 to 35 Nm - I/O interface for integration into the manufacturing process - Auto-Learn function: easy programming - Memory for five parameter sets, sequence can be run individually or sequentially - Lockable with a key - For series: SKD-RBN, SKD-TBN - Inputs: Start, Reverse - 1 power supply unit - 2-meter connection cable - 1 user manual
