Emerson UNI1403 Unidrive 1.5 kW 400 V Three Phase AC Drive

The Emerson UNI1403 is a 1.5 kW three-phase AC drive from the Control Techniques Unidrive Classic series. Designed for industrial motor speed and power control, the UNI1403 operates in the 400 V voltage class and supports a wide range of motor-control applications.

For customers searching for an Emerson UNI1403, UNI1403 AC drive, or Control Techniques Unidrive UNI1403 replacement, understanding the drive's electrical specifications and application requirements is important before purchasing a spare or replacement unit.

The UNI1403 is a Size 1 Unidrive Classic AC drive with a nominal power rating of 1.5 kW / 2 HP. Its three-phase AC input is designed for the 380–480 VAC range, making it suitable for industrial motor applications using common 400 V-class power systems.

The drive provides a continuous output current of approximately 3.8 A and a typical input current of approximately 5.8 A. Technical documentation identifies UNI1403 as a 1.5 kW drive with a 3.8 A continuous current rating.

For buyers looking for this legacy AC drive, the complete model number is essential because different UNI1400-series models have different power and current ratings.

The technical documentation confirms the UNI1403 1.5 kW rating and 3.8 A continuous output current.

The UNI1403 is rated for 1.5 kW / 2 HP applications. This makes it suitable for smaller industrial motors where controlled speed, acceleration and deceleration are required.

The drive belongs to the 400 V class and supports 380–480 VAC three-phase input, making it suitable for many industrial electrical systems.

The Unidrive platform supports several control approaches, including open-loop V/f, open-loop vector and closed-loop vector control. Documentation also identifies servo and regenerative operating modes within the Unidrive platform.

The UNI1403 is a Size 1 drive designed for industrial control panels and motor-control systems. Its IP20 enclosure is intended for installation inside a suitable electrical cabinet or protected control environment.

The UNI1403 can be used in industrial equipment where variable-speed motor control is required.

Typical applications may include:

• Industrial conveyor systems

• Pumps and circulation equipment

• Fans and ventilation systems

• Material-handling machinery

• Machine tools

• Production equipment

• Industrial automation systems

• Motor speed regulation

• Replacement of existing Unidrive Classic installations

When selecting a replacement, engineers should compare the original drive's motor rating, input voltage, output current, control requirements and application duty rather than selecting a drive based only on physical appearance.

If an existing UNI1403 has failed, check the complete drive label before ordering a replacement. Important identification information includes:

Model: UNI1403
Series: Unidrive Classic
Power: 1.5 kW / 2 HP
Input: Three-phase 380–480 VAC
Output current: 3.8 A

The UNI1400 family contains several models with different ratings. For example, UNI1401 is 0.75 kW, UNI1402 is 1.1 kW, UNI1403 is 1.5 kW, UNI1404 is 2.2 kW and UNI1405 is 4.0 kW.

Therefore, UNI1403 should not be replaced simply by another UNI1400-series model without checking the motor and application requirements.

Because the Unidrive Classic platform is an older product family, customers searching for UNI1403 spare parts, UNI1403 replacement drives and existing-system maintenance components may need to source from industrial automation suppliers with legacy inventory.

If you are looking for the exact model, you can view our product page for the [Emerson UNI1403 AC Drive] and check availability, condition and purchasing information.

For maintenance departments, purchasing teams and system integrators, confirming the exact part number before ordering can help avoid receiving an incorrectly rated drive.

Industrial AC drives that look similar can have significantly different electrical ratings. A 1.1 kW UNI1402, 1.5 kW UNI1403 and 2.2 kW UNI1404 are not interchangeable simply because they belong to the same Unidrive family.

When purchasing a UNI1403 replacement, compare:

1. Exact model number

2. Input voltage

3. Number of phases

4. Motor power

5. Continuous output current

6. Required control mode

7. Existing system configuration

8. Physical installation requirements

This approach is especially important when maintaining older production machinery where replacing the original drive with an incorrect model could require additional engineering work.

UNI1403 is a Control Techniques Unidrive Classic AC drive rated at 1.5 kW / 2 HP for 400 V-class three-phase applications.

The UNI1403 is designed for a three-phase 380–480 VAC supply, with the commonly specified 400 V class within this range.

The documented continuous output current for UNI1403 is 3.8 A.

It can be used as a replacement only when the exact electrical rating, motor requirements, control method and installation requirements are compatible. Always verify the complete model number before purchasing.
