Product Description

Allen-Bradley SP-135893 Precharge SCR Board for 1336 75 HP Drives

The Allen-Bradley SP-135893 precharge board kit is a dedicated printed circuit board assembly used in compatible 1336 series variable frequency drives rated at 75 HP. It manages SCR firing during the precharge phase to control inrush current and stabilize DC bus voltage at startup.

SCR Precharge Control Functionality

  • Controls SCR firing during drive power-up
  • Supports DC bus voltage stabilization
  • Designed for 1336-series drive architecture
  • OEM-specific PCB assembly format

Drive Architecture Integration

This board operates as part of the internal power management system within supported 1336 drives. By regulating precharge behavior, it helps ensure proper electrical sequencing during motor startup under rated load conditions.

Industrial Applications

  • Motor control systems using Allen-Bradley 1336 drives
  • 75 HP industrial VFD installations
  • Drive maintenance and service part replacement
