Description
Product Name: 1333-YAA Allen Braley Programmable controller
Product details:
The Allen-Bradley Bulletin 1333 is a legacy series of Adjustable Frequency AC Drives (Variable Frequency Drives or VFDs). It was designed to control the speed, torque, and direction of standard 3-phase AC induction motors.
It converts fixed-voltage, fixed-frequency utility power into a variable voltage and frequency output using Pulse Width Modulation (PWM) technology. It was widely used in industrial automation before being succeeded by modern families like the PowerFlex series.
⚙️ Product Parameters (Specifications)
While specific ratings depend on the exact catalog suffix, the standard Bulletin 1333 series parameters typically fall within the following ranges:
| Parameter | Standard Specifications (Typical for 3HP units like 1333-BAA) |
| Input Voltage | 200–230V AC (or 460V AC depending on the model), 3-Phase |
| Output Voltage | 0 to Input Voltage, 3-Phase |
| Power Range | Typically available up to 5 HP for standard frame sizes |
| Output Frequency | Variable (typically 0–60 Hz or 0–120 Hz) |
| Control Method | Volts per Hertz ($V/f$ control) / PWM (Pulse Width Modulation) |
| Enclosure Rating | Open style or NEMA Type 1 (IP20) |
| Overload Capacity | Typically 150% for 60 seconds |
| Operating Temp | 0°C to 50°C (32°F to 122°F) ambient |
✅ Product Advantages (Benefits)
Despite being an older generation drive, the Bulletin 1333 was highly regarded for several key features:
-
Energy Savings: By controlling motor speed to match actual load requirements (rather than running at constant full speed), it drastically reduces energy consumption—especially in centrifugal fan and pump applications.
-
Mechanical Protection: Smooth acceleration and deceleration “soft-starting” eliminate the harsh mechanical shocks associated with across-the-line starting, extending the lifespan of belts, gears, and motors.
-
Robust Construction: Built to heavy-duty industrial standards traditional to Allen-Bradley, making them highly reliable in harsh factory environments.
-
Simplified Integration: Straightforward I/O terminals for standard start/stop, forward/reverse, and speed potentiometer wiring.
⚠️ Important Considerations & Precautions
Since this is a legacy/obsolete drive, special care must be taken:
-
Obsolete Status: The 1333 series is discontinued. Finding brand-new OEM units is nearly impossible; most available units on the market are refurbished, surplus, or used.
-
Thermal Management: When mounting in an enclosure, ensure sufficient clearances (typically at least 4.0 inches on top/bottom and 2.0 inches on sides) to allow the heat sink fins to dissipate heat. Do not let the internal ambient temperature exceed 50°C.
-
Capacitor Aging: If a drive has been sitting unused on a shelf for years, the DC bus electrolytic capacitors can fail if full voltage is applied instantly. They should be “reformed” (brought up to voltage slowly) before being put into operation.
-
Modern Upgrades: For new installations, it is highly recommended to upgrade to a modern Allen-Bradley PowerFlex drive, which offers better efficiency, communication protocols (Ethernet/IP), and active manufacturer support.
🏭 Product Applications
The Bulletin 1333 AC drives were standard workhorses in manufacturing and process industries for applications such as:
-
Conveyor Systems: Synchronizing belt speeds and controlling material flow.
-
Fans and Blowers: Modulating airflow in HVAC and industrial ventilation systems.
-
Pumps: Maintaining fluid pressure and flow control in water treatment or chemical processing.
-
Material Handling: Controlling automated industrial machinery, packaging equipment, and basic machine tools.
