PLC 25A-D017N104 7.5 kW Three-Phase AC Drive

Product Overview

The 25A-D017N104 is a variable frequency AC drive for controlling the speed and torque of three-phase induction motors. It operates from a 380–480V AC three-phase supply and provides a rated output current of 17.0 A. This model supports a motor rating of 7.5 kW or 10 Hp in both normal-duty and heavy-duty applications. Its programmable output-frequency range extends from 0 to 500 Hz, allowing engineers to configure motor speed, acceleration and deceleration for different machine loads. Motor-control options include volts-per-hertz control, sensorless vector control and sensorless vector control with an energy-saving mode. Operating commands can be received from the integral keypad, control terminals, built-in RS485 interface or an optional communication adapter. The 25A-D017N104 uses a Frame C housing with IP20 open-type protection. The N104 configuration does not contain an integral EMC filter.

Application Areas

Conveyor and Material-Handling Systems--The 25A-D017N104 can regulate conveyors used for bulk transfer, accumulation, sorting and production-line movement. Controlled acceleration can reduce belt slip and limit stress on gearboxes, couplings and transported materials.

Pumps and Ventilation Equipment--The drive can control process pumps, circulation systems, cooling fans and industrial ventilation equipment. Adjusting motor speed to actual flow or pressure demand may improve process stability and reduce unnecessary energy use.

Mixers and Agitators--It is suitable for mixers, agitators and blending equipment powered by motors up to 7.5 kW. Sensorless vector control can improve torque response when the process must operate consistently across different speed ranges.

Frequently Asked Questions

Q1. What motor size is suitable for 25A-D017N104?
The drive is rated for a 7.5 kW or 10 Hp three-phase induction motor. The motor nameplate current should not exceed the drive’s 17.0 A rated output, and the required starting torque must remain within the permitted duty rating.

Q2. Can this model operate from a single-phase supply?
No. The 25A-D017N104 is specified for a 380–480V AC three-phase supply. The incoming voltage, phase arrangement, grounding system and branch-circuit protection should be verified before installation.

Q3. What should be considered when managing the 221 W heat loss?
The control cabinet must provide enough airflow to keep the drive within its permitted operating temperature. Engineers should maintain the required mounting clearances and include the 221 W heat loss in the cabinet thermal calculation.
