By purchasing this item, you agree to the Terms & Conditions, ApterPower is not an authorized distributor for listed manufacturers or tradenames and therefore the manufacturer's warranty does not apply. All our products come with ApterPower's 1-year warranty.
Provides 4.0 kW three-phase motor control from a 380–480 V mains supply.
Supports current-vector, V/f and field-oriented control strategies.
Integrates thermal, short-circuit, earth-fault and voltage supervision.
The current ordering configuration is the size-1 NORDAC SK 700E inverter with the complete -401-340-A suffix and 4.0 kW rating.
It regulates motor speed and torque in cabinet-mounted machine and process-drive applications using selectable control methods.
Before commissioning, match the motor nameplate, mains fuse, braking arrangement, optional control interface and ventilation clearances to the installed system.
Availability is subject to Apter Power's current inventory and sourcing confirmation.

Internal protection monitors inverter temperature, short circuits, earth faults, overload and DC-link voltage conditions.
UL application data specifies a Class J 15 A branch fuse and the published 380/460–480 V motor ratings for this configuration.
Protective earthing, feeder protection and cabinet access controls must follow the installation manual and local electrical rules.
The control platform supports sensorless current-vector, linear V/f and field-oriented motor-control modes selected during commissioning.
Optional control technology provides analog references, motor-temperature input and programmable signal processing for the installed drive task.
Optional bus modules support system integration through documented interfaces such as CANopen, PROFIBUS DP, DeviceNet, InterBus or serial communication.
The documented drive efficiency is approximately 95% under the stated operating conditions.
Short-duration torque demand is supported by 150% overload for 60 seconds and 200% overload for 3.5 seconds.
The 3–20 kHz switching range allows acoustic and motor-performance adjustment, with 6 kHz used as the standard setting in this power range.
Description
SK700E-401-340-A is a NORD DRIVESYSTEMS NORDAC SK 700E frequency inverter for three-phase 380–480 V supplies. This size-1 configuration is rated 4.0 kW at 400 V and provides controlled three-phase output for industrial motors.
The inverter supports sensorless current-vector control, linear V/f control and field-oriented operation, with adjustable output frequency for speed regulation in machines and process equipment.
Before installation, confirm the complete suffix, motor data, mains protection, control option, braking requirement and cabinet clearances. Do not assume that a current NORDAC PRO unit is a drop-in replacement.

FAQS
The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How can the exact SK700E-401-340-A ordering configuration be identified?
Match the complete -401-340-A suffix, the 4.0 kW rating and the 380–480 V three-phase input data on the nameplate before ordering.
Which motor-control options are compatible with SK700E-401-340-A?
The platform supports sensorless current-vector, linear V/f and field-oriented control; installed I/O or bus functions depend on the fitted option modules.
Where is SK700E-401-340-A typically applied?
It is suited to cabinet-mounted variable-speed drives for conveyors, pumps, fans and machine equipment when the motor and load profile fit the inverter rating.
What is the sourcing status of SK700E-401-340-A?
NORD publishes migration guidance for the SK 700E family; Apter Power confirms actual stock, condition and lead time for each enquiry.
Can SK700E-401-340-A be replaced directly by a NORDAC PRO inverter?
No direct drop-in interchangeability should be assumed. Compare dimensions, terminals, braking, motor data, options, parameters and fieldbus requirements using the migration guide.
What should be included in an SK700E-401-340-A documentation or quotation request?
Provide the complete suffix, nameplate photo, motor rating, mains voltage, option modules, braking requirement, quantity and destination so the correct documents and offer can be checked.
