About MD5204T355SINT AC Drive, Three Phase, 380V to 480V,355kw - Inovance Ac Drive

The Inovance MD520 355 kW AC Drive (Model: MD5204T355S-INT, sometimes formatted as MD5204T355SINT) is a high-power industrial variable frequency drive (VFD). This high-capacity unit operates within the T12 frame size classification, sharing its physical dimensions with the 315 kW variant while providing increased current throughput. [1, 2]

Physical Dimensions & Weight (T12 Frame Size)

The footprint dimensions and physical weight converted to imperial units from the manufacturer's technical engineering guide are: [1]

Height (Total Length): 55.31 inches (\(1405\text{ mm}\))
Width: 15.75 inches (\(400\text{ mm}\))
Depth (Thickness): 21.46 inches (\(545\text{ mm}\))
Net Weight: 407.86 lbs (\(185.0\text{ kg}\))

Cabinet Backplate Mounting Layout

For heavy floor or custom electrical enclosure panel anchoring, apply these drilling centerline specifications:

Horizontal Pitch Spacing: 9.45 inches (\(240\text{ mm}\))
Vertical Pitch Spacing: 50.39 inches (\(1280\text{ mm}\))
Mounting Fixing Bolt Hole Size: 0.63 inches (Requires heavy M16 bolts)

System Architecture & Dynamic Protections

Dynamic Braking Requirements: This 355 kW drive requires an external braking unit arrangement consisting of three or four units parallelly configured (such as the MDBUN-200-5T series) to handle high-inertia deceleration or heavy mechanical feedback safety loops.
Harmonic Distortion Mitigation: Standard design integrates a built-in internal DC reactor to clamp grid harmonics and satisfy strict industrial grid regulations. [1]
Atmospheric Resilience: Features a premium 3C3 and 3S2 level conformal coating across internal PCBs to completely isolate electronics from dampness and conductive workshop dust. [1]
Functional Safety Integration: Equipped with standard dual-channel hardware Safe Torque Off (STO) terminals certified directly to SIL3 PL e protection standards. [1, 2]

Please specify if you need the required input line fuse ratings or circuit breaker curves for your electrical enclosure layout, or if you need help planning minimum top and bottom thermal clearances for cabinet ventilation.
