The VACON NXP04166-A2L0SSB-A1A2000000 functions as a high-performance inverter unit within the NXP Common DC Bus family,This Braking Chopper Unit-compatible inverter suits heavy-duty crane hoists,steel mill coilers,marine propulsion drives,paper machine winders.
What Is a Common DC Bus Inverter Unit?
A common DC bus inverter unit is a power conversion module that receives a fixed DC voltage from a shared DC link and converts it into variable-frequency,variable-voltage AC output to control the speed and torque of a three-phase motor.Unlike a standalone AC drive that contains its own rectifier,DC link,and inverter within one enclosure,a common DC bus inverter contains only the inverter stage and draws power from a centralized rectifier or active front-end(AFE)unit shared across multiple drives.

The VACON NXP series offers four system drive configurations on the common DC bus platform:Active Front-End(NXA),Non-Regenerative Front-End(NXN),Brake Chopper Unit(NXB),and Inverter(NXI).The NXP04166-A2L0SSB-A1A2000000 belongs to the NXP product range(code"NXP"in position 1–3 of the type designation)and serves as an inverter unit per VACON type designation code,configured with 380–500 V mains voltage,416 A rated current,IP00 enclosure,alpha-numeric control panel,and T-class EMC emission level compliance for IT(ungrounded)network operation.The unit occupies Frame 10 mechanical size and operates as a 6-pulse inverter with integral DC choke for current harmonic mitigation per industry-standard drive system architecture.

Technical Highlights
Closed-loop vector control achieves 0.01%static speed accuracy and 200%starting torque at zero speed,enabling precise synchronization of motor shafts in multi-motor line-shaft replacement applications.This directly supports high-performance coordination when the inverter unit is deployed alongside a separate Braking Chopper Unit in a common DC bus system serving synchronized winding or unwinding stations.
Common DC bus topology with external NXB brake chopper integration allows regenerative braking energy generated by one motor to be absorbed by other drives on the same DC link,reducing total energy consumption by up to 30%compared to individual braking-resistor-dissipation architectures.Only excess energy beyond simultaneous consumption is routed to the external brake chopper unit and dissipated in resistors.
Six-pulse input with integrated DC choke reduces input current total harmonic distortion(THDi)without requiring a dedicated 12-pulse transformer,lowering installation footprint and cost.This is the standard electrical modification code"S"in the VACON type designation system for NXP-based inverter and BCU modules.
Five programmable expansion slots accept fieldbus,additional I/O,and functional safety option boards that insert directly into the control board without external adapters,simplifying panel wiring and reducing commissioning time.This slot architecture is common to both NXP inverter units and NXB Braking Chopper Unit configurations,ensuring consistent spare parts strategy across the full common DC bus line-up.
Varnished conformal coating on printed circuit boards is a standard card modification option in the NXP/NXB build specification,protecting against moisture and corrosive atmospheres in wastewater treatment plants,offshore marine environments,and chemical processing facilities.
Applications
Crane and hoist main hoist motors:Delivers 200%starting torque at standstill in closed-loop vector mode with encoder feedback,holding full-load on vertical lifts without mechanical brake slip during initial lift-off and lowering sequences.
Steel and metal processing coilers/uncoilers:Maintains constant tension during winding and unwinding through closed-loop torque control with±0.01%speed regulation,operating with a separate Braking Chopper Unit to dissipate or redistribute deceleration energy from rapid strip speed changes to adjacent drives on the common DC bus.
Marine propulsion and thruster drives:Serves as a compact common DC bus inverter module in cabinet-assembled propulsion line-ups with up to 320 Hz output frequency for high-speed permanent magnet propulsion motors.Optional marine type approvals(Lloyd’s Register,NK)are configurable at order entry.
Paper machine sectional drives:Provides synchronized speed control across dryer sections,calender rolls,and reel-up stations when multiple NXP inverter units share a single DC bus with a centralized Braking Chopper Unit for emergency stop braking energy dissipation.
High-speed compressor test benches:Operates induction or permanent magnet motors at output frequencies up to 320 Hz for aerodynamic component testing,with 150%overload capability for 60 seconds at 50°C ambient enabling rapid acceleration and deceleration test cycles.
Mining conveyor and crusher drives:Handles shock loads and starting torque requirements through V/Hz scalar or open-loop vector control of induction motors.The IP00 open-chassis format integrates into sealed mining control cabinets,with conformally coated PCBs optional for dust and humidity protection.
Selection Guidance
Suitable for:
Common DC bus drive systems where multiple motors share a centralized rectifier or active front-end supply,and a separate NXB Braking Chopper Unit handles excess deceleration energy dissipation across the bus.
Heavy-duty applications requiring 150%overload capability for 1 minute at 50°C ambient and 200%starting torque at zero speed in closed-loop vector control mode.
IT(ungrounded)industrial networks in mining,marine,and offshore sectors where the T-class EMC emission level(IEC/EN 61800-3 C4)is mandatory for network compatibility.
Cabinet integration projects with in-house panel building capability—the IP00 open-chassis format requires user-provided enclosure,cable terminations,and branch circuit protection.
High-speed motor applications up to 320 Hz,including permanent magnet synchronous motors when configured with motor-specific parameter sets.
Not suitable for:
Standalone AC drive installations requiring an integrated rectifier,EMC filter,and IP21/IP54 enclosure in a single wall-mounted unit.For this application,select the VACON NXS product range or an NXP wall-mounted drive variant.
Applications requiring a built-in brake chopper within the same module.The NXP04166-A2L0SSB-A1A2000000 is configured with brake chopper code"0"(no internal brake chopper)as confirmed by VACON type designation.For system-level braking,specify a separate NXB Brake Chopper Unit(e.g.,NXB05205 for 520 A on 380–500 V systems)matched to the braking power requirement.
Single-drive systems where regenerative energy return to the mains is preferred over brake-chopper-based dissipation.For this requirement,an NXA Active Front-End configuration regenerates excess braking power back to the supply network rather than dissipating it through brake resistors.
