VACON NXP00276-A5L0SSV-A1A2000000 Liquid Cooled VFD 525-690V 27A Vector Control Three Phase Inverter

　　VACON NXP00276-A5L0SSV-A1A2000000 is a Liquid Cooled VFD Three Phase Inverter engineered for the VACON NXP series.Operating at 525–690 Vac and delivering 27 A output current with a 22 kW(VT)power rating,it features IP00 open-frame mounting and advanced vector control for induction and permanent magnet motors.Designed for marine propulsion,offshore cranes,mining conveyors,and heavy industrial processes,the unit achieves a compact footprint through direct liquid cooling technology that eliminates large cooling fans and enables near-silent operation below 68 dB(A).

　　What Is a Liquid Cooled VFD?

　　A Liquid Cooled Variable Frequency Drive(VFD)is a motor control device that uses a circulating liquid coolant—typically a glycol-water mixture—to dissipate heat from power electronics,replacing traditional air-cooled heatsinks and fans.The primary cooling mechanism is direct liquid cooling,where coolant flows through cold plates in direct contact with IGBT power modules,achieving thermal conductivity approximately 23 times higher than forced air.Liquid cooled VFDs deliver up to 25%reduction in total life cycle costs compared to equivalent air-cooled solutions.

　　Within the NXP product family,the NXP00276-A5L0SSV-A1A2000000 is classified under the NXP Drive Module portfolio and serves as a Three Phase Inverter Unit.Its model code breakdown identifies it as a liquid-cooled variant supplying 525–690 Vac with a 27 A rated output current.The module eliminates the need for large cooling fans,achieving near-silent operation and enabling installation in environments where air quality is critical or space is severely constrained.

　　Technical Highlights

　　Direct liquid cooling achieves exceptionally high power density.By bypassing air as a heat transfer medium entirely,the drive operates with a significant reduction in physical volume—in some configurations,achieving a footprint 30%smaller than comparable air-cooled units.The sealed cooling circuit also eliminates the primary path for conductive dust ingress,a critical advantage in mining and offshore environments where air-cooled drive failures from contaminated heatsinks are common.

　　Conformal coated circuit boards provide enhanced reliability in corrosive atmospheres.All printed circuit boards receive a protective conformal coating that resists moisture,salt spray,and chemical vapors,per IEC 60721-3-3 Class 3C2 chemical limits for chemical vapors and Class 3S2 for mechanical particles(no conductive dust allowed).

　　Integrated Safe Torque Off(STO)and Safe Stop 1(SS1)ensure functional safety without external contactors.The drive incorporates the OPTAF safety board that prevents unintended torque generation on the motor shaft.These safety functions meet EN ISO 13849-1 Category 3 and IEC 61508 SIL 2 requirements,eliminating the need for external safety relays in many machine safety circuits.

　　Five plug-in expansion slots provide comprehensive connectivity and future-proofing.The modular backplane architecture accommodates fieldbus options including PROFIBUS DP,PROFINET IO,EtherNet/IP,EtherCAT,Modbus/TCP,and CANopen without requiring drive disassembly.Additional I/O,encoder interface,and functional safety boards can be added in the field,providing a investment protection pathway as automation architectures evolve.

　　An all-in-one software package streamlines commissioning and reduces engineering hours.Seven built-in software applications cover common machine control requirements including pump and fan control,PID regulation,winding control,and positioning functionality.The embedded PLC capability allows execution of custom logic directly on the drive processor,eliminating a separate controller for localized machine sequences.

　　Applications

　　Marine propulsion and thruster drives:Provides precise speed and torque control for azimuth thrusters and bow thrusters.The liquid-cooled design enables installation in engine room compartments with ambient temperatures up to 50°C without the noise and dust issues associated with fan-cooled drives,operating nearly silently with no large cooling fans required.

　　Offshore cranes and winches:Delivers 150%overload torque for 60 seconds during heavy lift operations,meeting the intermittent peak demand of hoisting without requiring oversizing of the drive.The modular design allows integration into common DC bus architectures found in active heave-compensated cranes.

　　Mining conveyors and crushers:Operates reliably in high-dust environments where conductive particles would otherwise bridge the isolation clearance on air-cooled units.The IP00 open-frame design with liquid cooling closes the cooling path entirely,eliminating forced air circulation through the electronics and achieving MTBF values exceeding 80,000 hours under rated conditions per typical manufacturer testing protocols.

　　Pump and fan applications:Achieves energy reductions of 20%–40%when replacing fixed-speed operation with variable-speed control using the built-in pump/fan application software.The drive supports both standard induction motors and high-efficiency permanent magnet motors without additional hardware.

　　Common DC bus systems:Integrates as a Three Phase Inverter in multi-drive configurations where multiple inverters share a common DC link supplied by an Active Front End or diode rectifier.The shared DC bus recovers braking energy and redistributes it to motoring sections,reducing overall energy consumption by up to 30%in regenerative applications.

　　Selection Guidance

　　Suitable for applications requiring operation in harsh environments:Mining,marine,offshore,and heavy industrial settings where high ambient temperatures and airborne contaminants are present.The liquid cooling system handles these environments without derating,as it does not rely on ambient air for heat rejection.

　　Suitable for space-constrained equipment rooms and machinery housings:The compact IP00 module eliminates the large clearance zones required for air intake and exhaust grilles,simplifying panel layout and enabling higher equipment density per square meter.

　　Suitable for noise-sensitive installations:With no large cooling fans,the drive operates at noise levels substantially below those of equivalent air-cooled drives.A common question from facility engineers is whether the coolant pump noise becomes the dominant sound source;in practice,modern coolant circulation pumps operate at 52–58 dB(A)at 1 m,which is comparable to background noise in most equipment rooms.

　　Not suitable for applications without access to a reliable cooling water loop:The liquid cooling system requires a continuous supply of treated coolant at specified flow rates and pressure.If the installation site lacks a redundant cooling water system,an air-cooled drive variant such as the NXP00276-A2T0SSV may be more appropriate.

　　Not suitable for outdoor installations without a climate-controlled enclosure:Although the drive's ambient operating temperature range spans-10°C to+50°C,the cooling liquid must remain above 0°C to prevent freeze damage.Installations subject to sub-zero conditions require a glycol-water mixture,typically 60/40 water-glycol for operation down to-40°C as measured at the drive coolant inlet.
