Benchtop High Voltage Power Supplies

Spellman’s Bertan brand of 230 Series high voltage power supplies provide regulated high voltage outputs from 1 to 30kV.  The low noise, linear topology employed results in extremely low output ripple specifications. These 12 to 15W units are inherently reversible by design, providing either positive or negative output polarity. The 230 Series is fully arc and short circuit protected. Excellent regulation specifi­cations are featured along with outstanding stability perfor­mance. 

Typical applications: 

  • HiPot Testing
  • Electrostatics
  • General Laboratory Usage

Isolated (Floating) Output-Option F 

Units up to and including 5kV can be provided with differential outputs capable of floating up to ±2kV from ground. Voltage programming and monitoring functions are normally referenced to ground. Current monitor­ing and metering is eliminated. Replace “R” suffix with “F” for this option. Output connectors (positive, negative and ground) for 1kV and 3kV models are 3-way binding posts; 5kV model uses Spellman P/N JAC for positive and negative outputs with 3-way binding post for ground. Mating connectors are Spellman P/N PA (MHV type 1705-14)
