The is a complex power supply responsible for generating multiple voltage rails from a standard AC input. Based on technical feedback and schematic analysis, its primary outputs are designed to drive the subwoofer amplifier circuits. Model Number: HYS3C210-CS

The is a specialized switch-mode power supply (SMPS) prominently used in high-fidelity home theater audio equipment . Most notably, it serves as the internal power hub for the Harman Kardon HKTS 200 subwoofer (powering the LFMA 00690 amplifier stage). Because subwoofers handle demanding low-frequency signals, their power supply units (PSUs) endure significant thermal and electrical stress.

Like many switching power supplies, the HYS3C210-CS can degrade over time due to heat and component stress. Common issues reported by users on forums like Reddit and Elektroda include:

is a critical component for restoring broken Harman Kardon subwoofers. Understanding its specs—particularly the 48V output and the ±7V rail—is crucial for diagnosis and repair.
