The FC-051P5K5T4E20HXBXCXXXSXXX (136N8934) is a rugged and compact frequency converter from the Danfoss VLT Micro Drive FC 51 series, engineered for high-density industrial environments. This 5.5 kW (7.5 HP) motor controller is designed to optimize the performance of three-phase AC motors in applications such as conveyor systems, industrial fans, and centrifugal pumps. By providing precise speed and torque control, the FC-051P5K5T4E20HXBXCXXXSXXX significantly enhances process efficiency while reducing mechanical stress on drivetrains. Its coated PCB architecture ensures long-term reliability in harsh operating conditions, making it a critical component for reducing energy consumption and minimizing operational overhead in modern manufacturing and water treatment facilities.
The technical capabilities of this specific unit are defined by its comprehensive configuration string, which dictates its hardware and software interface:
P5K5: Denotes a power rating of 5.5 kW (7.5 HP) optimized for heavy-duty industrial loads.
T4: Specifies three-phase input compatibility with a mains voltage range of 380 - 480 VAC.
E20: Chassis design rated at IP20, suitable for protected cabinet mounting.
HX: No RFI Filter configuration, ideal for setups where external filtering is already present or not required.
B: Integrated Brake Chopper, allowing the drive to dissipate regenerative energy during rapid deceleration or braking.
C: Coated Printed Circuit Boards (PCB) for enhanced protection against humidity, dust, and airborne contaminants.
X (LCP): Standard unit supplied without a Local Control Panel; requires external interface or separate LCP module for manual parameter adjustment.
| Feature | Specification |
| Model | FC-051P5K5T4E20HXBXCXXXSXXX |
| Brand | Danfoss |
| Part Number | 136N8934 |
| Power Rating | 5.5 kW / 7.5 HP |
| Mains Voltage | 380 - 480 VAC (3-Phase) |
| Enclosure Rating | IP20 / Chassis |
| Brake Chopper | Integrated |
| PCB Coating | Coated (Class 3C3 compatible) |

| Net Weight | 3.0 kg |
| Shipping Weight | 4.0 kg |
Does this model include a built-in display for parameter monitoring?
No, the "X" designation in the LCP position indicates that this unit does not come with a Local Control Panel. For setup and monitoring, you must use a remote mounting kit, an LCP 11/12 module, or the MCT 10 setup software via the RS485 interface.
Can the FC 51 be mounted side-by-side to save cabinet space?
Yes, the VLT Micro Drive features a unique bookstyle design that allows for true side-by-side mounting without derating. This enables maximum utilization of panel space in high-density electrical enclosures.
What is the benefit of the Coated PCB ("C" suffix) in this drive?
The conformal coating protects the internal electronics from corrosion and short circuits caused by moisture or conductive dust. This is essential for maintaining uptime in industries like textiles, woodworking, or chemical processing.
Cooling and Clearance: Despite the side-by-side mounting capability, ensure a minimum clearance of 100 mm above and below the unit. This maintains the necessary vertical convection airflow required to keep the internal heat sinks within safe operating limits at the 5.5 kW power rating.
Dynamic Braking Implementation: Since this model includes an integrated brake chopper (Suffix B), an external brake resistor must be connected to terminals R+ and R- to handle regenerative energy during high-inertia stops. Ensure the resistor value (Ohms) matches the minimum requirements specified in the Danfoss technical manual to prevent chopper damage.
Grounding and RFI Considerations: As this is the "HX" version (No RFI Filter), it is vital to use shielded motor cables and ensure a 360 degree low-impedance ground connection at both the drive and the motor. If the installation is near sensitive electronic equipment, consider installing an external RFI filter to mitigate electromagnetic interference.
