Typical Applications
- Semiconductor wafer fabrication (CVD, PVD, etch processes)
- Plasma surface treatment systems
- Thin-film deposition equipment
- Industrial RF power generator maintenance and MRO
- Research & development plasma systems
- Flat panel display (FPD) manufacturing lines
System Compatibility
- CESAR3-MAIN V2.1 (LY210109): Compatible with Advanced Energy CESAR3 series RF generators (typically 1–5 kW output range). Verify chassis model and firmware before ordering.
- C4-MAIN V4.0 (LY400268 / 2305173-A): Compatible with Advanced Energy CESAR C4 series generators. Cross-check unit serial number prefix for exact board revision match.
- Not interchangeable between CESAR3 and C4 series without engineering validation.
Selection Guide
| Your Generator Model | Recommended Board | Part Number |
|---|---|---|
| CESAR3 series (any wattage) | DRE CESAR3-MAIN V2.1 | LY210109 |
| CESAR C4 series | DRE C4-MAIN V4.0 | LY400268 / 2305173-A |
| Unknown / mixed revision | Contact Konmask for cross-reference | — |
Tip: Locate the silver label on your generator’s rear panel — it lists the exact board part number and revision installed at the factory.

Replacement & Compatibility FAQ
Q: Can I use the C4-MAIN V4.0 board in a CESAR3 chassis?
A: No. The CESAR3 and C4 series use different board form factors and firmware. Cross-installation requires engineering validation and is not recommended.
Q: Is V2.1 backward compatible with V2.0 slots?
A: In most cases yes, but confirm with your service manual or contact Konmask before ordering.
Q: Do you supply refurbished boards?
A: Yes. Refurbished boards are tested, cleaned, and shipped with a 90-day warranty. Specify “refurbished” when inquiring.
Q: What is the lead time for out-of-stock boards?
A: Typically 2–4 weeks for sourcing. Contact us for urgent requirements.
Q: Can you provide a certificate of conformance?
A: Yes, available on request for both new and refurbished units.
