ELECTRONIC BALLAST FOR MSD 350 R17 YODN

Competitive Advantages

Unlike generic models, the YODN unit implements a calibrated ignition curve that minimizes thermal stress on the lamp electrodes. The electronic control technology ensures a constant 350W output, preventing brightness drops and significantly extending the light source's operational lifespan compared to traditional electromagnetic ballasts.

FAQ for Installers

Can I use this power supply for lower wattage lamps, such as the 330W R15?

Absolutely not. The control electronics are specifically calibrated for the impedance and arc voltage of the 350W R17. Using it with lower wattage lamps would cause an "over-driving" phenomenon, leading to the explosion of the lamp's discharge chamber or irreversible overheating of the ballast circuits.

Does this ballast support "Hot Restrike" (hot ignition)?

No. MSD 350 R17 discharge lamps require the internal gas pressure and electrode temperature to drop before a new ignition. The YODN ballast manages ignition attempts intelligently, but it is necessary to wait for the cooling cycle (typically 2–5 minutes) programmed into the moving head software to avoid unnecessary stress on the igniter.

What thermal precautions should be taken when mounting it inside the fixture?

It is fundamental that the ballast's metal surface is in contact with the projector's chassis or that a constant airflow of at least 15–20 m³/h is guaranteed. Overheating the unit not only reduces efficiency but can trigger the internal thermal protection, causing the lamp to shut down during the show.
