Amplifiers

FANUC-Amplifier Alpha i-series

Featuring power source regeneration and low power loss devices, this is the energy efficient solution. Built using a modular structure with αiPS (power supply), αiSP (spindle amplifier) and αiSV (servo amplifier), these models come with built-in leakage detection functionality and a safe torque off function in the servo and spindle amplifier. Maintenance is easy. Replacing the circuit board and fan does not require disassembly.

Key Features

  • modular structure with αiPS (power supply), αiSP (spindle amplifier), and αiSV (servo amplifier) 
  • compact amplifier unit for 1 spindle & 3 axes
  • built-in Leakage Detection function 
  • Safe Torque Off function in servo and spindle amplifier 
  • quick maintenance by circuit board and fan replacement without disassembly 
  • 75/100kW spindle amplifier (400V) with high efficient SIC (silicon carbide) power circuit available 
  • Various power supply modules αiPSs with sinusoidal input – stabilized DC link 
  • SSM modules for voltage protection of spindle and servo amplifier

FANUC Amplifier Beta i series

The cost effective solution with an integrated power supply. This range comes with a servo amplifier for up to two axes or as compact spindle plus servo amplifier unit for one spindle and up to three servo axes. Benefiting from low power loss, they also feature a safe torque off function. Maintenance is easy and replacing the circuit board and fan does not require disassembly. There is a servo amplifier suitable for auxiliary axes, and with the βiSVSP / βiSVSPc models makes a very affordable choice for small and medium size compact lathe machines.
