About MD5204T18.5BS-INT AC Drive, Three Phase, 380V to 480V,18.5kw - Inovance Ac Drive

The Inovance MD520 18.5 kW AC Drive (Model: MD5204T18.5BS-INT) is a high-performance variable frequency drive (VFD). While sharing the exact electrical capacity, T5 frame size, and STO safety options as the standard 18.5S variant, the specific "B" designation confirms an integrated, factory-fitted internal braking chopper unit built right into the chassis.

Device Measurements (T5 Frame Size)

The physical footprint dimensions and total mass converted to imperial units are:

Height (Total Length): 13.78 inches (\(350\text{ mm}\))
Width: 8.27 inches (\(210\text{ mm}\))
Depth (Thickness): 7.56 inches (\(192\text{ mm}\))
Net Weight: 20.06 lbs (\(9.1\text{ kg}\))

Cabinet Backplate Mounting Layout

If you are mapping out internal subpanels or machining cabinet backplates, use these centerline spacing parameters:

Horizontal Pitch Spacing (Hole Width): 7.68 inches (\(195\text{ mm}\))
Vertical Pitch Spacing (Hole Height): 13.19 inches (\(335\text{ mm}\))
Mounting Fixing Bolt Hole Diameter: 0.24 inches (Designed for standard M5 fixing bolts)
