203 Series

Overview

The 203 Series of capacitor chargers delivers high-power performance in a compact 7U design, enabling easy integration into existing systems. With output voltages from 1 kV to 50 kV, the chargers provide the flexibility to meet a wide range of demanding applications. Passive power factor correction supports reliable energy delivery while protecting your electrical system.

Features and applications

  • High power capability with up to 25 kJ/s peak charging for rapid capacitor recharge
  • Wide output voltage range from 0–1 kV to 0–50 kV for flexible system configuration
  • Evaporative cooling and insulation for stable operation at high power levels
  • IGBT-based resonant inverter for efficient, reliable energy conversion
  • 208, 400 or 480 VAC three-phase input for compatibility with standard supplies
  • Ultra-compact, water-cooled rack-mount design for space-constrained installations
  • Parallel operation support to scale power output as requirements increase
  • Suitable for lasers, grid bias supplies, PFNs, modulators, precipitators and lithotripters

Detail

Peak charging up to 25 kJ/s supports rapid capacitor charging, allowing high-intensity processes to run at the required pace with consistent results, while the water-cooled architecture keeps operations stable under continuous load to prevent overheating and downtime.

Precise, repeatable charging maintains predictable pulse-to-pulse performance, supporting your demanding operating conditions without interruption.
