PLC 25A-D030N104 15 kW Three-Phase AC Drive

Product Overview

The 25A-D030N104 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 30.0 A. The model has different motor ratings according to the load classification. It supports 15 kW or 20 Hp in normal-duty applications and 11 kW or 15 Hp in heavy-duty applications. Engineers must select the rating according to the required overload capability rather than relying only on the motor’s nominal power. Its programmable output-frequency range extends from 0 to 500 Hz. Motor-control options include volts-per-hertz control, sensorless vector control and sensorless vector control with an energy-saving mode. The drive uses a Frame D housing with IP20 open-type protection.

Application Areas

Pumps and Ventilation Systems--The 25A-D030N104 can operate pumps, cooling fans, extraction fans and ventilation equipment under its 15 kW normal-duty rating. Motor speed can be matched to pressure, flow or airflow demand to improve process control.

Conveyor and Material-Handling Equipment--The drive can regulate conveyors used for loading, bulk transfer and production-line material movement. The correct normal-duty or heavy-duty rating should be selected according to starting torque, load variation and acceleration requirements.

Mixers and Agitators--For loads requiring higher starting torque or frequent load changes, the 11 kW heavy-duty rating may be more appropriate. Sensorless vector control can improve motor response when the mixer or agitator operates at reduced speed.

Processing and Production Machinery--The model can control production auxiliaries, processing machines and equipment requiring adjustable motor speed. Programmable acceleration, deceleration and operating commands allow the drive to be matched to the machine cycle.

Frequently Asked Questions

Q1. Should 25A-D030N104 be selected as a 15 kW or an 11 kW drive?
It depends on the load. The model is rated for 15 kW or 20 Hp under normal-duty conditions and 11 kW or 15 Hp under heavy-duty conditions. Applications requiring greater overload capacity should use the heavy-duty rating.

Q2. Why is the heavy-duty power rating lower than the normal-duty rating?
Heavy-duty loads require additional current capacity during acceleration or sudden load changes. The lower 11 kW rating preserves the necessary overload margin, while the 15 kW normal-duty rating is intended for loads with less demanding torque characteristics.

Q3. Does the N104 configuration include an EMC filter?
No. This configuration does not contain an integral EMC filter. If filtering is required, engineers should select an external filter after reviewing the supply system, cable length, grounding and cabinet arrangement.
