PLC 25A-D4P0N104 1.5 kW Three-Phase AC Drive

Product Overview

The 25A-D4P0N104 is a variable frequency AC drive designed for speed and torque control of three-phase induction motors. It operates from a 380–480V AC three-phase supply and provides a rated output current of 4.0 A. This model supports a motor rating of 1.5 kW or 2 Hp in both normal-duty and heavy-duty applications. Its programmable output-frequency range extends from 0 to 500 Hz, allowing motor operation to be matched to the speed and acceleration requirements of the machine. Available motor-control methods include volts-per-hertz control, sensorless vector control and sensorless vector control with an energy-saving mode. Operating commands can be received from the built-in keypad, control terminals, RS485 interface or a compatible optional communication adapter. The 25A-D4P0N104 uses a compact Frame A housing with IP20 open-type protection. This N104 configuration does not contain an integral EMC filter. Filtering, branch protection, motor cables and grounding must be selected according to the installation environment.

Application Areas

Conveyor and Transfer Systems--The 25A-D4P0N104 can regulate conveyors used for product movement, sorting and positioning. Adjustable acceleration and deceleration help reduce belt slip, sudden load movement and mechanical shock.

Pumps and Ventilation Equipment--The drive can vary the speed of small industrial pumps, cooling fans and ventilation equipment. Matching motor speed to actual demand may improve process control and reduce unnecessary power consumption.

Mixers and Agitators--It can control the operating speed of mixers, dosing equipment and agitators with motors rated up to 1.5 kW. Sensorless vector control can provide improved torque performance during low-speed operation.

Packaging and Processing Machines--The model is suitable for feeders, packaging mechanisms, sealing machines and other equipment requiring adjustable motor speed. Its digital inputs allow operating commands to be coordinated with the machine sequence.

Frequently Asked Questions

Q1. What motor size can be connected to 25A-D4P0N104?
The drive is rated for a 1.5 kW or 2 Hp three-phase induction motor. Engineers should confirm that the motor nameplate current does not exceed the drive’s 4.0 A rated output and that the application torque remains within the permitted duty rating.

Q2. How does 25A-D4P0N104 differ from 25A-D2P3N104?
The 25A-D4P0N104 is rated at 1.5 kW, 2 Hp and 4.0 A. The 25A-D2P3N104 is rated at 0.75 kW, 1 Hp and 2.3 A. Although both use a Frame A housing, they should not be interchanged without checking the motor current, load and protection requirements.

Q3. Is an EMC filter integrated into 25A-D4P0N104?
No. The N104 configuration is supplied without an integral EMC filter. If filtering is required, the external filter and associated wiring should be selected according to the motor cable length, grounding arrangement and site environment.
