Important Notice 1: Continuous operating time must not exceed 2 minutes per cycle. Prolonged operation beyond 2 consecutive minutes cause excessive heat buildup in the high‑voltage multiplier, leading to insulation breakdown, irreversible damage, and a significant reduction in service life. Important Notice 2: The AC input range is strictly 2KV-15KV and must never exceed 15KV . Over‑voltage conditions over‑stress internal components, burn the circuit board, and may result in arcing, smokes, or complete module failure, so verify the driver output carefully. Must be used with a suitable driver plus high‑voltage pack to provide a 2KV-15KV AC input; directly connect this high‑frequency AC output to the module AC terminals. Do not power from other types of supplies or DC sources, or bypass the driver, or the module may fail or perform unstably. This product is an expansion accessory only and must be paired with a high‑frequency, high‑voltage module to operate. It does not function as a standalone power supply and requires an appropriate high‑frequency driver, matching impedance and voltage, and proper insulation and safety protection. Maximum theoretical boost ratio is 24 times; for example, an AC input of about 2500V can reach up to approximately 60000V at the output. Designed for recommended 100V-2500V AC at around 50KHz, with reserved redundancy margins to support more stable long‑term high‑voltage output conditions., Manufacturer: Ounfhtrttk
