PLC 25A-D2P3N104 0.75 kW Three-Phase AC Drive

Product Overview

The 25A-D2P3N104 is a compact variable frequency drive for controlling three-phase AC induction motors in machine and process applications. It accepts a 380–480V AC three-phase supply and delivers a rated output current of 2.3 A. The drive supports a motor rating of 0.75 kW or 1 Hp in both normal-duty and heavy-duty applications. Its output frequency can be programmed from 0 to 500 Hz, allowing motor speed, acceleration and deceleration to be matched to the connected equipment. Motor-control options include volts-per-hertz control, sensorless vector control and sensorless vector control with an energy-saving mode. Commands can be received through the control terminals, built-in keypad, RS485 interface or an optional communication adapter. This configuration uses a compact Frame A housing with IP20 open-type protection. It does not include an integral EMC filter. External filtering, cable routing, grounding and branch-circuit protection must therefore be selected according to the installation requirements.

Application Areas

• Small Conveyor Systems
The 25A-D2P3N104 can control the speed of light-duty conveyors used for product transfer, sorting and positioning. Adjustable acceleration and deceleration may reduce belt slip, product movement and mechanical shock.

• Pumps and Ventilation Fans
The drive can regulate small pumps, cooling fans and localized ventilation equipment. Matching motor speed to process demand can reduce unnecessary energy use and improve control of flow or airflow.

• Packaging Equipment
It is suitable for feeders, sealing machines, labeling equipment and compact packaging mechanisms. Digital inputs can be assigned to start, stop, direction and preset-speed commands within the machine sequence.

Frequently Asked Questions

Q1. What motor size can be connected to 25A-D2P3N104?
The drive is rated for a 0.75 kW or 1 Hp three-phase AC motor in both normal-duty and heavy-duty applications. The motor nameplate current should not exceed the drive’s 2.3 A rated output unless the complete application has been reviewed separately.

Q2. How does 25A-D2P3N104 differ from 25A-D1P4N104?
The 25A-D2P3N104 is rated at 0.75 kW, 1 Hp and 2.3 A. The 25A-D1P4N104 is rated at 0.4 kW, 0.5 Hp and 1.4 A. Both use the same voltage class and Frame A format, but they should not be interchanged without checking the motor current and load requirements.

Q3. How can a PLC control the drive?
A PLC can issue start, stop, direction and speed commands through the digital and analog terminals. Communication is also possible through the built-in RS485 interface using Modbus RTU/DSI or through a compatible optional adapter.
