Related Product Features:
  • Supplies stable DC power to servo amplifiers in CNC and automation systems with a three-phase 200-230 VAC input.
  • Features built-in regenerative discharge circuitry to safely dissipate energy from decelerating motors and prevent voltage spikes.
  • Incorporates protective mechanisms against overcurrent, undervoltage, overvoltage, and excessive temperature.
  • Includes clear LED indicators for power ready (RDY), alarm (ALM), and control power (CNT) conditions for easy fault identification.
  • Delivers a rated output of 283-325 VDC with a power rating of 18.5 kW, suitable for heavy-duty multi-axis configurations.
  • Designed for reliable operation within an ambient temperature range of 0°C to 55°C with internal forced-air cooling.
  • Compatible with Fanuc Alpha servo amplifiers (SVM, SVMi) and CNC controllers like Series 0i, 16i, 18i, 30i, and 31i.
  • Compact dimensions (approx. 150mm W x 300mm H x 200mm D) and 6kg weight allow for practical installation in standard enclosures.
FAQs:
  • What is the input voltage and power rating of the Fanuc A06B-6078-H206 Power Supply Module?
    The module accepts a three-phase input of 200-230 VAC at 50/60 Hz and has a power rating of 18.5 kW, delivering a rated DC output of 283-325 VDC.
  • How does the regenerative discharge circuitry benefit the CNC system?
