A-B 1336-FAN-SP2A Cooling Fan 1336 Series Adjustable Frequency AC Drives

The 1336-FAN-SP2A is part of the 1336 series of adjustable frequency AC drives. It is designed for use in 1336 Plus, 1336 Force, 1336 Impact,

1336 Plus Regen and 1336 plus II drives, specifically Frame D drives rated at 60 HP, 75 HP, 100 HP, 125 HP and X150 HP.

The 1336-FAN-SP2A is a cooling fan assembly that is the primary cooling unit for the 1336 adjustable frequency AC drive product line manufactured by Allen-Bradley.

The fan assembly is designed for use with 1336 Plus, 1336 Force, 1336 Impact, 1336 Plus Regen, and 1336 plus II drives.

Especially drives with D-frames or power ratings of 60 HP, 75 HP, 100 HP, 125 HP and X150 HP.

The 1336-FAN-SP2A includes a CHB1 fan capacitor, which is black in colour.

The fan is internally powered from a 115 VAC supply and is rated at 0.67 amps and 75 watts.

The fan is rated at 2550 revolutions per minute (rpm). 1336-FAN-SP2A is designed to prevent the drive from overheating.

The relevant drive parameter that can be used to determine the operation of the fan is the overheat fault parameter 08. This drive fault is defined as an excessive heat sink temperature that exceeds a predetermined value of 90 degrees Celsius or 195 degrees Fahrenheit.

1336-FAN-SP2A is an obsolete component of the 1336 series. It is classified by the manufacturer as a Class 3 discrete component and recommended stock locations include GTS.

When replacing an existing fan with a new component, power to the drive must be disconnected to prevent the risk of electrical shock.

To get the most out of the 1336-FAN-SP2A cooling fan, the drive's mounting clearance must be met to ensure adequate airflow.

Improper mounting may cause early deterioration of the drive and generate abnormal high temperature warnings that could affect the daily operation of the 1336-FAN-SP2A.

The Allen-Bradley/Rockwell Automation 1336-FAN-SP2A cooling fan is part of the C Series of the Rockwell Automation 1336 Spare Parts family.

The 1336-FAN-SP2A is designed for D-frame drives and is KC certified. The fan is part of the RGU power structure for use with Series A RGUs.

The RGU (Regenerative DC Bus Power Unit) is a regenerative front-end to a shared DC bus drive system that facilitates bi-directional power flow between the shared bus and the AC input (three-phase).

Since regenerative generator sets tend to heat up during operation, the 1336-FAN-SP2A is required to regulate the temperature.

In addition to cooling regenerative units, the 1336-FAN-SP2A is also used to cool controllers that drive induction motors used in industrial field sensitive applications.

Note that only one 1336-FAN-SP2A cooling fan is required per drive or any bus-powered configuration.

The 1336-FAN-SP2A can also be used as a fan replacement for the Frame D 1336 VFD.

The 1336-FAN-SP2A provides cooling for major components that tend to overheat, such as heat sinks and memory modules.

Before installing the 1336-FAN-SP2A on a hard disc, it should first be tested for proper function, including direction of rotation, as this will affect the effectiveness of its cooling system.

For example, reverse rotation draws air from the outside of the drive into the inside of the drive, while reverse rotation draws air from the inside of the drive into the outside space.

Pulling air from the drive may have a drying effect that can exacerbate overheating.
