● Product Overview
The DBW/SBW [S] - SK series CNC dedicated single-phase and three-phase power stabilizers are digital products that use a microcomputer (MCU) control system. The use of ARM's new 32-bit processor, fully digital control, true RMS sampling and display, effectively overcomes the phenomena of "loss of control" and "distortion". The CNC dedicated voltage regulator has high precision and good stability, and the overall performance fully meets the high requirements of imported CNC equipment for input power supply. The core technology of CNC equipment is servo controller and servo motor, which belong to typical nonlinear loads (rectification, inversion, linear power regulation, etc.). The obvious feature of this type of load is the large high-order current harmonic components, which cause distortion of the voltage sine wave. In the above application environment, control and measurement errors are inevitably generated by general voltage regulators and analog instruments. This model adopts digital filtering FIR algorithm, which effectively solves the above problems and is particularly suitable for harsh power quality environments of CNC equipment.
