Allen-Bradley 1336R-PRE-SP1A

The Allen-Bradley 1336R-PRE-SP1A pre-charge PCB is an essential part of the 1336 REGEN series, expertly crafted to control voltage build-up in the DC Bus of variable frequency drives. This component is crucial for high-demand applications such as conveyors and elevators, enabling regenerative drives to efficiently redirect energy back to the 3-phase AC power line instead of dissipating it as heat. Featuring a 3-phase contactor and a precise monitoring circuit, this board guarantees accurate phase and voltage readings while effectively limiting inrush current. With an operating voltage of 460 Volts and a current rating between 48 and 78 Amps, it significantly enhances system reliability and efficiency, making it a valuable addition to your automation setup.
