The is a specialized switching power supply (PSU) unit primarily known for its role in high-end audio equipment, specifically within Harman Kardon active subwoofers like the HKTS 200 model . As a critical component of the internal amplifier system, it manages the conversion of mains voltage into the stable DC rails required to drive heavy bass loads. Technical Specifications and Capabilities
Finding a direct retail replacement for the HYS3C210-CS can be difficult, as it is often sold as a "service-only" part.
The unit may power on (standby light is active), but no sound is produced because the high-voltage rail for the amplifier has failed. hys3c210-cs power supply
Typically outputs 48V DC to power the Class D power amplifier.
The subwoofer fails to turn on, often caused by a blown fuse or a failure in the primary switching MOSFET. The is a specialized switching power supply (PSU)
Often indicates a failure in the +/-7V standby circuit , preventing the main controller from booting the system. Troubleshooting and Repair Tips
Provides symmetric +/-7V DC for the standby circuitry and pre-amplifier stages. The unit may power on (standby light is
Check for bulging or leaking electrolytic capacitors. Specifically, the high-voltage capacitor (e.g., 3.3µF 400V) is a known failure point that can cause the unit to stop functioning.
