1336VT-B020-EOP-L3/A Allen Bradley

Description

Product Name: 1336VT-B020-EOP-L3/A  Allen Braley Power module

Product details:  

The Allen-Bradley 1336VT-B020-EOP-L3/A is a legacy Adjustable Frequency AC Drive from the 1336 PLUS/VT series. This specific model is designed for high-performance control of induction motors, particularly in applications requiring variable torque.

## 1. Product Description

The 1336VT series is engineered for Variable Torque (VT) applications. The “B020” designation indicates this is a mid-range power unit designed to operate on 460V AC power. It utilizes Pulse Width Modulation (PWM) technology to provide precise motor speed and torque control, ensuring energy efficiency in centrifugal loads.

## 2. Technical Specifications

## 3. Key Product Options (Suffix Codes)

• EOP: Refers to the specific Program/Control options and firmware revision included in the factory build.

• L3: Indicates a 115V AC Control Interface. This means the digital inputs (Start/Stop, Forward/Reverse) operate on a 115V AC logic level rather than 24V DC.

• A: Typically denotes the hardware series or original revision code.

## 4. Product Advantages

• Energy Efficiency: Specifically tuned for fans and pumps, reducing power consumption during low-demand periods.

• Robust Protection: Includes features like overvoltage, undervoltage, and short-circuit protection to safeguard both the drive and the motor.

• Proven Reliability: Although it is a legacy product, the 1336 series is known for its heavy-duty industrial build quality and long service life.

• Flexible Programming: Offers extensive parameter sets for precise acceleration/deceleration ramps and skip frequencies (to avoid mechanical resonance).

## 5. Common Applications

This drive is primarily used in HVAC and heavy industrial fluid management:

1. Centrifugal Pumps: Water treatment, chemical processing, and irrigation.

2. Industrial Fans: Cooling towers, exhaust systems, and AHUs (Air Handling Units).

3. Blowers: Used in pneumatic conveying and aeration.

4. Compressors: Where variable speed is required to maintain constant pressure.

## 6. Important Considerations & Precautions

• Legacy Status: This model is Discontinued by Rockwell Automation. New units are rare; most available units are “Remanufactured” or “Refurbished.”

• Capacitor Aging: Because these are older units, the internal electrolytic capacitors may degrade if left unpowered for long periods. If the unit has been sitting in storage for over a year, it may require “reforming.”

• Heat Dissipation: Ensure the cabinet has adequate ventilation. The “Open” enclosure (EOP) requires a clean, dust-free environment to prevent internal short circuits.

• Replacement Strategy: If this drive fails, it is often recommended to migrate to the PowerFlex 750 or 755 series using a conversion kit, as modern drives offer better communication protocols (EtherNet/IP).
