Bertan 205B-20R

Spellman’s Bertan brand of 205B Series high voltage power supplies provide regulated high voltage outputs from 1 to 50kV. The low noise, linear topology employed results in extremely low output ripple specifications. These 15 to 30W units are inherently reversible by design, providing either positive or negative output polarity. The 205B is fully arc and short circuit protected. Excellent regulation specifications are featured along with outstanding stability performance. 

Typical high voltage applications:

• HiPot Testing
• CRT Testing
• Electrostatics
• E Beam Systems
• General Laboratory Usage
