The BohER AF03A/B/C high‑voltage power supplies provide adjustable output voltages from 6 kV to 20 kV, up to 10 W power and >75 % efficiency.
BohER (波尔) High Voltage Power Supply Co., based in Suqian, China, collaborates with Genvolt (UK) to produce the AF03 series of high‑voltage power supplies. The series is intended for industrial applications requiring stable, efficient high‑voltage output.
Key specifications include input voltage 12 V DC (± tolerance), maximum input current 0.8 A, efficiency greater than 75 %, selectable output voltages 6‑20 kV, stability under 3 %, maximum output power 10 W, and temperature coefficient below 300 ppm/°C. Physical dimensions vary by model: AF03A (70 × 45 × 25 mm), AF03B (90 × 60 × 25 mm), AF03C (120 × 40 × 25 mm). This manual is written in Chinese.
