Eaton Variable Speed Drive, 90kW Rated Operational Power, 400V ac Nominal Voltage - 134489 SPX125A1-4A1B1

This variable speed drive is designed to control 3-phase motors in industrial settings, offering adjustable frequency operation for process and motor control applications. It operates from 380 to 500 V mains and supports sensorless Vector, optional closed-loop Vector and U/f control modes. Built for panel installation with IP21 protection, the unit includes an OLED Interface and integrated brake chopper to manage dynamic braking and support continuous motor operation across a wide frequency range.

Features and Benefits:

• 90 kW rated power supports high-load motor applications
• 400 V AC three-phase output enables standard industrial supply compatibility
• 150% overload capability for short-term torque demands
• Adjustable switching frequency up to 10kHz reduces acoustic and thermal stress
• Integrated radio interference suppression filter lowers conducted emissions

Applications

• Suitable for pumps requiring variable flow control
• Ideal for conveyor systems with frequent speed changes
• Used with fans where energy-efficient speed control is required
• Can be used for compressors needing soft-start and braking control

What protection class applies to the enclosure?

The unit is rated IP21 for protection against ingress and contact.

Which control interfaces are available for network integration?

Multiple bus options are supported as factory- or optional-fitted modules including PROFIBUS-DP, Modbus-RTU, Profinet, EtherCAT, EtherNet/IP, DeviceNet, CANopen, BACnet/IP and BACnet MS/TP.

How does the drive handle elevated altitude or temperature?

It is specified for use up to 3,000 m with a performance de-rating above 1,000 m at 1% per 100 m and an ambient operating range from -10 °C to 50 °C.

What safety and conformity standards are covered?

Certification includes UL508C, IEC/EN 61800-3, IEC/EN 61800-5, CE, RoHS, ISO 9001 and approvals listed under CSA Class No. 3211-06.

What control and I/O options are fitted for process signals?

The control circuit offers 2 analogue inputs, 6 digital inputs, 1 analogue output, 1 digital output and 2 relay outputs Plus a 24 V DC control supply.
