Input Voltage: 537–679 VDC (400V series)
Rated Input Current: 33.5 A at 585V
Output Voltage: 400 VAC nominal (Max 480 VAC)
Output Current: 22.5 A for the L-axis / 22.5 A for the M-axis
Frequency Range: 0 to 550 Hz

Physical Specs & EnvironmentDimensions (H x W x D): 378 mm x 58 mm x 168 mm (14.9″ x 2.3″ x 6.6″)
Weight: Approx. 5.5 kg (12.1 lbs)
Cooling: Forced air cooling (internal fan)
Operating Temp: 0°C to 55°C (32°F to 131°F)

Key FeaturesCompatibility: Designed for Fanuc CNC controllers (like the 0i-MD, 0i-TD, and 31i series) using the FSSB (Fanuc Serial Servo Bus) optical fiber interface.
Efficiency: Part of the (alpha )i-B series, which features a slimmer design and reduced heat generation compared to older models.
Applications: Typically used in high-precision milling and turning centers requiring high-voltage power distribution
