PLC 25A-D024N104 11 kW Three-Phase AC Drive

Product Overview

The 25A-D024N104 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 24.0 A. This model supports a motor rating of 11 kW or 15 Hp in both normal-duty and heavy-duty applications. Its programmable output-frequency range extends from 0 to 500 Hz, allowing motor speed, acceleration and deceleration to be configured for the connected machinery. Motor-control options include volts-per-hertz control, sensorless vector control and sensorless vector control with an energy-saving mode. Commands can be received from the integral keypad, control terminals, built-in RS485 interface or an optional communication adapter. The 25A-D024N104 uses a Frame D housing with IP20 open-type protection. The N104 configuration does not contain an integral EMC filter. Cabinet ventilation, electrical protection, grounding and motor-cable routing must be evaluated during system design.

Application Areas

Conveyor and Material-Handling Systems--The 25A-D024N104 can regulate conveyors used for bulk material movement, loading, transfer and production-line transport. Controlled acceleration helps reduce belt slip and mechanical stress when starting heavier loads.

Pumps and Water-Handling Equipment--The drive can adjust the speed of process pumps, circulation pumps and water-handling equipment. Matching motor speed to actual pressure or flow demand may improve process stability and reduce unnecessary energy consumption.

Fans and Ventilation Systems--It is suitable for extraction fans, cooling systems and industrial ventilation equipment driven by motors up to 11 kW. Adjustable speed allows airflow to be matched to changing process requirements.

Mixers and Processing Machinery--The model can control mixers, agitators and processing equipment requiring adjustable motor speed. Sensorless vector control can improve torque response where the load changes during operation.

PLC-Controlled Production Equipment--The drive can be integrated into PLC-controlled machinery through digital inputs, an analog reference or RS485 communication. Optional communication adapters may be selected when another supported network method is required.

Frequently Asked Questions

Q1. What motor size is suitable for 25A-D024N104?
The drive is rated for an 11 kW or 15 Hp three-phase induction motor. The motor nameplate current should not exceed the drive’s 24.0 A rated output, and the required starting torque must remain within the selected duty rating.

Q2. Can this model operate from a single-phase input?
No. The 25A-D024N104 is specified for a 380–480V AC three-phase supply. The incoming voltage, phase arrangement, grounding system and branch-circuit protection must be verified before installation.

Q3. How does 25A-D024N104 differ from 25A-D017N104?
The 25A-D024N104 is rated at 11 kW, 15 Hp and 24.0 A and uses a Frame D housing. The 25A-D017N104 is rated at 7.5 kW, 10 Hp and 17.0 A and uses a smaller Frame C housing. Their dimensions, input current and heat dissipation are different.
