PLC PN-173122 PN-200959 Inverter power supply board

Frequently asked questions
Q:What is the PN-173122 PN-200959?
A:The PN-173122 PN-200959 is an internal power supply and inverter gate drive printed circuit board used in compatible PLC industrial drive systems. It is supplied as a replacement electronic assembly for maintenance applications.

Q:Is the PN-173122 PN-200959 a complete drive?
A:No. It is an internal PCB assembly installed inside a compatible drive and is not intended to operate as a standalone product.

Q:Does the board provide isolated power outputs?
A:Yes. The assembly generates multiple regulated low-voltage DC supplies for internal control circuits and incorporates galvanic isolation between the control electronics and the power stage.

Description

The PLC PN-173122 PN-200959 is an internal power supply and gate drive circuit board used in compatible industrial drive systems. It forms part of the inverter electronics and operates between the control circuitry and the power switching section of the drive. The board converts the internal DC bus power into regulated low-voltage supplies required by the drive control circuits. At the same time, it transfers gate drive signals from the control section to the power semiconductor devices used in the inverter stage. These functions allow the control electronics and power section to operate together during normal drive operation. As a replacement component, the PN-173122 PN-200959 is intended for maintenance of existing PLC drive equipment.

Application areas

The PLC PN-173122 / PN-200959 is an internal combination power supply and gate drive circuit board primarily utilized within PowerFlex variable frequency drives (VFDs), its core application areas include:

• High-Power Gate Inverter Section Switching: Acts as the dedicated internal firing circuitry required to send high-speed trigger pulses to Thyristor, Triac, or IGBT power semiconductors during active inversion loops. 
• Industrial Automation Machinery Stabilization: Deployed as a critical drop-in replacement part within heavy industrial sectors (automotive, assembly plants, and material handling lines) where motor control systems cannot tolerate torque ripples or signal delays.
• Dual-Function Modular Space Saving: Combines two critical system layers—the power distribution network and the inverter gate triggering mechanism—onto a single  360-gram printed circuit board (PCB) to optimize the internal footprint of compact drive chassis.
