AD (Analog-Digital) Current Control Repairing Services
Specialized Repair & Calibration of Precision Current Control Systems

AD current control systems are critical in applications that require accurate regulation of current using analog-to-digital conversion techniques. These systems are widely used in industrial automation, power electronics, motor drives, battery chargers, and welding systems. Malfunction in AD current control units can lead to unstable performance, damaged components, or process errors.

• Signal analysis of input/output current loops

• Verification of analog-to-digital conversion accuracy

• Detection of drift, noise, or zero-offset issues

• Load behavior and response curve evaluation

• Replacement of damaged op-amps, shunt resistors, ADCs, and FET drivers

• Repair or replacement of isolation circuits, current sensors (Hall effect, shunt, etc.)

• Rework of SMD components and PCBs under ESD-safe conditions

• Firmware diagnostics and flashing

• MCU/DSP repair or replacement (if programmable control is involved)

• Communication interface repair (UART, SPI, I²C for AD control feedback loops)

• Current loop calibration and zero/scale adjustment
