The HYS3C210-CS is a specific Power Supply Unit (PSU) model commonly used in high-end audio equipment, most notably the Harman Kardon HKTS 200 subwoofer [1]. hys3c210-cs
It is frequently discussed in DIY electronics circles because it is a common point of failure for these subwoofers, leading users to seek repairs or replacements. Technical Specifications & Output
This power supply is designed to provide specific voltages to the subwoofer's internal components:
Main Output: 48V, which powers the primary audio amplifier (such as model LFMA 00690) [1].
Secondary Outputs: +7V, -7V, and Ground (GND), used for low-voltage circuitry like the preamp or control board [1]. Common Issues & Troubleshooting If your subwoofer fails to turn on or make sound, the HYS3C210-CS is often the culprit.
Symptom: The 48V output may fail completely while the lower-voltage +/- 7V rails continue to function [1].
Diagnosis: Technicians often check for visible capacitor swelling or "sparking" and use a multimeter to verify if the 48V terminal is dead [3, 8].
Causes: Common causes for failure include age-related wear, thermal stress, or power surges [9, 10]. Replacement and Repair
Since exact manufacturer replacements for this specific board can be difficult to find, DIYers often consider two paths:
Direct Board Repair: Replacing faulty components (like capacitors or MOSFETs) on the HYS3C210-CS board.
External Substitute: Using a generic 48V power supply. However, this is technically challenging because you must also find a way to provide the separate +/- 7V required by the system [1].

The HYS3C210-CS is a internal power supply unit (PSU) primarily found in high-end audio equipment, most notably the Harman Kardon HKTS 200 subwoofer. It is an essential component for converting AC wall power into the specific DC voltages required by the subwoofer's internal amplifier. Key Specifications
Based on technical documentation and user repairs for this specific model: Voltage Outputs: The HYS3C210-CS is a power supply unit (PSU)
Main Rail: 48V DC (used to power the main LFMA 00690 amplifier board).
Secondary Rails: +/- 7V DC (used for auxiliary logic and low-power circuits).
Input Range: Typically universal AC input (approx. 100–240V AC), though some regional variants may exist.
Design: Open-frame internal PCB design intended for integration inside a speaker cabinet rather than a standalone desktop adapter. Known Issues & Maintenance
The HYS3C210-CS is frequently discussed in repair communities due to specific failure patterns:
Voltage Failure: A common fault where the 48V rail fails while the +/- 7V rails remain functional, causing the subwoofer to power on (LED lit) but produce no sound.
Serviceability: Schematic guides for similar models like the HYS3B210-CS are often used as references for troubleshooting the circuitry of this specific unit. Applications Primary Device: Harman Kardon HKTS 200 Subwoofer.
Replacement Notes: Due to its niche 48V output and specific physical dimensions, it is typically replaced with an identical OEM unit or bypassed by experienced hobbyists using a 48V battery bank or external industrial 48V power supply for testing.
