Product Details

1336-PB-SP23C Product Description

The Allen-Bradley 1336-PB-SP23C is a factory-original power board designed for the 1336 PLUS series of AC variable frequency drives. As a core energy-control component, it governs the gate-drive signals, DC bus regulation, and thermal protection logic that determine how efficiently a drive converts incoming AC power into precisely controlled motor output. In smart production environments where every kilowatt-hour counts, the 1336-PB-SP23C plays a decisive role in sustaining drive efficiency, reducing heat dissipation, and keeping production lines running at their designed throughput.

Sourced directly from verified industrial supply channels, each 1336-PB-SP23C unit at NANKMOS undergoes pre-shipment functional testing to confirm gate-signal integrity, bus-voltage sensing accuracy, and fault-relay response. Stock is maintained on-hand for rapid dispatch, supporting maintenance teams that cannot afford extended drive downtime. A 12-month warranty covers every unit shipped.

The 1336-PB-SP23C does not operate in isolation — it is the energy-control heart of a broader drive system that spans multiple automation layers. In a typical Rockwell Automation architecture, a ControlLogix or CompactLogix PLC issues speed and torque references to the 1336 PLUS drive over a DeviceNet or DH+ network. The 1336-PB-SP23C translates those references into precise IGBT gate pulses, ensuring the motor receives only the power it needs at any given load point. This load-adaptive switching is what separates an energy-optimized drive from one running at fixed-frequency waste.

On the monitoring side, a PowerMonitor 3000 or PowerMonitor 5000 power-quality meter installed upstream of the drive panel captures real-time kW, kVAR, and harmonic data. When the 1336-PB-SP23C is functioning correctly, the drive's input power factor remains high and harmonic distortion stays within IEEE 519 limits — deviations in those metrics are often the first sign that a power board is degrading. Pairing the drive with a 1336-MOD-C2 communication module allows SCADA systems such as FactoryTalk View SE to pull drive fault codes and energy counters directly, enabling predictive maintenance before a board failure causes unplanned downtime.

For motor-side efficiency, the 1336 PLUS drive controlled by this power board is frequently paired with Kinetix servo drives on adjacent machine axes, where coordinated motion profiles reduce peak-demand spikes across the shared DC bus. On I/O-intensive lines, 1756 ControlLogix I/O modules relay discrete feedback from current sensors and thermal switches back to the PLC, which can then command the drive to reduce speed during low-load windows — a strategy that directly cuts energy consumption during non-peak production intervals. A PanelView Plus HMI gives operators real-time visibility into drive status, output frequency, and fault history, closing the loop between energy data and operator action.

A failing or degraded power board in a 1336 PLUS drive manifests in ways that silently erode production efficiency long before a hard fault occurs. Increased switching losses raise the drive's internal temperature, forcing cooling fans to run longer and harder. Inaccurate gate signals cause the motor to draw more current than the load demands, inflating energy bills and accelerating winding insulation wear. Intermittent DC bus faults trigger nuisance trips that interrupt production rhythm, forcing operators into manual restart cycles that break line synchronization and reduce overall equipment effectiveness (OEE).

Replacing a worn 1336-PB-SP23C with a verified OEM-specification board restores the drive to its designed efficiency curve. In pump and fan applications — where the affinity laws mean that a 10% reduction in motor speed cuts power consumption by roughly 27% — having a power board that accurately executes speed commands is directly tied to energy savings. In conveyor and material-handling lines, consistent drive response eliminates the micro-stops and speed variations that disrupt production takt time and cause downstream buffer overflows.

NANKMOS maintains ready stock of the 1336-PB-SP23C to support just-in-time maintenance strategies. Each unit is tested for gate-signal symmetry and bus-voltage sensing before dispatch, and ships with full documentation. The 12-month warranty provides coverage against manufacturing defects, giving maintenance engineers confidence that the replacement board will perform to specification for a full production cycle without requiring re-intervention.

Q1: Will the 1336-PB-SP23C restore my 1336 PLUS drive to its original energy efficiency rating? Yes. The 1336-PB-SP23C is an OEM-specification power board. When installed correctly, it restores the drive's IGBT gate-drive timing and DC bus regulation to factory parameters, which directly recovers the drive's designed output efficiency and reduces excess heat generation.

Q2: Which 1336 PLUS drive frame sizes and voltage ratings is this board compatible with? The 1336-PB-SP23C is designed for specific frame configurations within the 1336 PLUS and 1336 PLUS II families. Please verify your drive's catalog number and frame size against the Rockwell Automation 1336 PLUS spare-parts cross-reference before ordering. NANKMOS technical support can assist with compatibility confirmation.

Q3: What does the pre-shipment testing process cover? Each unit undergoes functional verification of gate-signal output integrity, DC bus voltage sensing accuracy, and fault-relay response prior to dispatch. This ensures the board is operationally sound before it reaches your facility, reducing the risk of a repeat failure event on the production floor.

Q4: What does the 12-month warranty cover, and how is a claim initiated? The 12-month warranty covers defects in materials and workmanship under normal operating conditions. If a board fails within the warranty period, contact NANKMOS at [email protected] or +86 18359268345 to initiate a return and replacement. Warranty claims are typically processed within 5 business days of the defective unit being received.
