Description
Product Name: 1336-SP-135736 Allen Braley Central control module
Product details:
The Allen-Bradley 1336-SP-135736 is a specialized spare part/component within the 1336 series of Adjustable Frequency AC Drives. Specifically, this part number refers to a Pre-Charge Board (often categorized under the 1336 PLUS, PLUS II, or IMPACT series).
Below is a detailed breakdown of the product specifications and technical context.
Product Overview
The 1336-SP-135736 is an internal PCB (Printed Circuit Board) designed to manage the “soft-start” or pre-charge sequence of the drive’s DC bus. Its primary role is to limit the inrush current when power is first applied, protecting the bridge rectifier and capacitors from damage.
Technical Parameters
| Parameter | Specification |
| Manufacturer | Rockwell Automation / Allen-Bradley |
| Series | 1336 PLUS / PLUS II / IMPACT |
| Component Type | Pre-Charge Board |
| Voltage Class | Typically used in 460V – 575V AC Units |
| Compatibility | Frame E and Frame F Drives (High Horsepower) |
| Function | Inrush current limitation and DC bus monitoring |
Product Advantages
-
System Protection: Prevents catastrophic failure of the DC bus capacitors by ensuring a gradual charge.
-
OEM Reliability: As a genuine Allen-Bradley part, it ensures exact timing for relay/contactor closures required by the drive’s firmware.
-
Extends Drive Lifespan: By managing thermal stress during power-up cycles, it preserves the integrity of the power modules (IGBTs).
-
Plug-and-Play Integration: Designed specifically for the 1336 chassis, requiring no modifications to the existing mounting or wiring harness.
Important Considerations & Safety
Warning: Industrial drives contain high-voltage capacitors that can hold a lethal charge even after the main power is disconnected.
-
Discharge Time: Wait at least 5–10 minutes after powering off the drive. Verify that the DC bus voltage is at zero with a voltmeter before installation.
-
ESD Protection: This board is sensitive to Electrostatic Discharge (ESD). Always wear a grounding wrist strap during handling.
-
Firmware/Revision Match: Ensure that the “SP” (Spare Part) number matches your drive’s manual exactly, as different frames require different pre-charge rates.
-
Check Surrounding Components: If a pre-charge board has failed, it is often due to a shorted bridge rectifier or a faulty DC bus capacitor. Inspect these components before installing the new board.
Product Applications
The 1336 series drives (and this pre-charge board) are commonly found in heavy-duty industrial environments, including:
-
Material Handling: Conveyor systems and automated sorting lines.
-
HVAC Systems: Large centrifugal pumps and industrial fans.
-
Manufacturing: Used in plastic extrusion, paper mills, and textile production.
-
Oil & Gas: Controlling large motors for pumping and compression where precise speed control is vital.
