SEAM Mode for Enhanced Efficiency

The PXB Series features SEAM Mode, allowing current to flow bidirectionally without altering voltage values—making it ideal for charging and discharging storage batteries. This capability effectively suppresses current overshoots and undershoots, achieving high-speed rise and fall times.

Variable Internal Resistance & I-V Characteristic Function

• Simulated Internal Resistance: Adjusts output voltage values in constant voltage mode based on set resistance values, allowing for simple simulation of rechargeable battery internal resistance and wire harness characteristics.
• Customizable I-V Characteristics: Users can define up to 100 arbitrary points for I-V characteristics, facilitating accurate battery and device simulation in both CC and CV operation modes.

Reliable Performance in Harsh Environments

Engineered for durability, the PXB Series operates seamlessly in extreme conditions, maintaining solid performance in temperatures ranging from 0°C to 50°C. This ensures reliable functionality even in demanding installation environments.

Safety and Protection Features

Safety is paramount in power supply operations. The PXB Series is equipped with multiple protection functions to safeguard both the equipment and operators:

• Priority Operation Mode: Prevents overshoot by setting CC mode priority when connecting batteries and power supplies.
• External Control Function: EXT CONT connector enables integration with external devices for advanced system control.

• Protection Functions for Safety Operation

  • OVP (Over voltage protection)
  • UVP (Under voltage protection)
  • WDOG (Communication error protection)
  • OPP (Over power protection)
  • OCP (Over current protection)
  • EXT LOW (External input alarm detection)

With its unparalleled combination of power, efficiency, and safety, the Kikusui PXB Series sets a new benchmark in bidirectional DC power supplies. CN Rood continues to lead the way in delivering cutting-edge solutions for the evolving technological landscape.
