High Power and High Voltage Up to 60 W, 40 kV in the Compact Module

The RA/RB series is a line of compact, chassis-mount high-voltage power supply modules designed for high stability and low ripple. The series includes the RB model (low ripple) and the RA model (ultra-low ripple), allowing users to select the optimal performance for their specific needs.
These modules are ideal for photomultiplier tubes (PMTs), electron beam applications, and various inspection systems. Their compact form factor allows for easy integration into smaller systems, offering greater design flexibility for OEM equipment. Standard features include output voltage and current monitors, along with arc and continuous short-circuit protection. All models are CE marked, with UL/cUL certified options available.

FEATURES AND BENEFITS

  • RB models: Low ripple, high stability
  • RA models: Ultra-low ripple, high stability
  • Compact & High Power: Up to 60 W and 40 kV in a space-saving chassis-mount design
  • Safety & Reliability: Features arc protection and continuous output short-circuit protection
  • Flexible Control: Output control via external potentiometer or control voltage (0 to 5 Vdc)
  • Global Compliance: CE marking (Low Voltage Directive) standard; UL60950-1 / CSA60950-1 (cUL) certified models available

APPLICATIONS

The RA/RB series is a versatile high voltage power supply module trusted across a wide range of demanding fields. Its exceptional performance and reliability make it the go-to choice for the following applications:
