The 1336-QOUT-SP19A is an output reactor designed for use with Allen-Bradley 1336 series adjustable frequency AC drives. This component is an essential power option for reducing dV/dt (voltage rate of rise) and is required when the cable distance between the drive and the motor exceeds the manufacturer’s recommended limits.
dV/dt Suppression
Reflected Wave Reduction
3% Impedance Filtering/span>
This reactor provides a 3% impedance at the drive's rated output current, effectively filtering the PWM (Pulse Width Modulation) waveform before it reaches the motor terminals. It limits the magnitude of reflected wave peak voltages and reduces motor operating temperature by smoothing the current waveform in industrial power circuits.

HVAC Systems
Controls fan and blower speeds in large commercial units where long vertical cable runs are common. It reduces dV/dt to protect motor insulation from premature failure caused by reflected wave peak voltages.
Water Treatment
Operates centrifugal pumps and aerators in municipal treatment facilities with remote motor locations. This module filters the PWM waveform to ensure reliable motor operation over extended cable distances between the drive and the pump.
Oil and Gas
Manages electric submersible pumps and secondary recovery equipment in demanding field environments. It smoothing the current waveform to decrease motor operating temperature and enhance the reliability of the entire power circuit.
Material Handling
Regulates long-distance belt conveyors and automated sorting systems in distribution centers. The reactor provides a 3% impedance to mitigate electromagnetic interference (EMI) and maintain system integrity across extensive wiring networks.
Chemical Processing
Drives mixers, agitators, and metering pumps in corrosive or hazardous environments. It limits the magnitude of reflected wave voltages at the motor terminals, extending the life of standard induction motors used in continuous processes.
Mining Operations
Controls heavy-duty crushers and ventilation fans in underground or surface mining sites. The unit is designed to handle high-power motor applications, reducing the voltage rate of rise to prevent insulation breakdown in harsh industrial settings.
The 1336-QOUT-SP19A must be installed in series between the AC drive output terminals and the motor, requiring a secure vertical mounting within a ventilated enclosure to ensure adequate convection cooling for the inductor coils. All power to the drive and reactor must be disconnected to prevent electrical shock, and the magnetic field generated by the reactor must not interfere with low-voltage control circuits during operation.
This module is rated for continuous operation in ambient temperatures up to 50°C (122°F), and regular maintenance should include inspecting for signs of overheating and verifying all terminal connections remain tight to maintain low-resistance contact.
What is the primary purpose of installing the 1336-QOUT-SP19A in a drive system?
The 1336-QOUT-SP19A is designed to reduce the dV/dt of the drive output waveform and minimize the magnitude of reflected wave peak voltages at the motor terminals.
When is the 1336-QOUT-SP19A specifically required for motor cable runs?
It is required when the distance between the drive and the motor exceeds the recommended cable length to protect the motor insulation system from potential damage.
What is the standard impedance rating of the 1336-QOUT-SP19A module?
The 1336-QOUT-SP19A provides a 3% impedance at the drive’s rated output current to ensure proper filtering of the pulse width modulated (PWM) signal.
Does the 1336-QOUT-SP19A affect the voltage received by the motor?
A typical 3% voltage drop across the reactor will occur and must be accounted for in applications requiring full motor nameplate voltage.
What are the installation requirements regarding the mounting orientation for 1336-QOUT-SP19A?
The module must be mounted in a vertical orientation within an enclosure to allow for adequate convection cooling of the inductor coils.
