Features:

  • Provides the dedicated parallel connection required for high-power GTO inverter systems.
  • Distributes synchronized trigger and pulse control signals to parallel GTO driver boards.
  • Supports master drive architecture in the ABB ACV 700 Frequency Converters Series with unchanged external connections.
ABB SNAT620PCB is developed for industrial applications where higher output current and greater power capacity are achieved by operating multiple GTO inverter units in parallel. The board serves as the connection point between the master unit and parallel power stages, allowing the complete drive system to function as a coordinated whole. Its role is particularly valuable in large ACV 700 installations that demand reliable power sharing.

Signal synchronization is another important function of ABB SNAT620PCB. In addition to connecting the main power circuits, the board distributes trigger and pulse signals from the master control board to multiple GTO driver boards with consistent timing. Accurate signal distribution helps parallel inverter sections switch together, supporting stable operation under varying industrial loads.

ABB SNAT620PCB operates from a 24 V DC power supply and is suitable for operating temperatures between 0°C and +55°C, with storage temperatures from -40°C to +70°C. The IP00 protection rating makes the board appropriate for installation inside protected electrical cabinets. Combined with the master drive architecture of the ACV 700 Frequency Converters Series, ABB SNAT620PCB provides an effective solution for parallel GTO inverter applications.

The SNAT620PCB ABB Parallel Connection Board (GTO) may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
ABB SNAT620PCB is a parallel connection board (GTO) used in the ABB ACV 700 Frequency Converters Series. The board supports parallel inverter configurations by providing the connection platform required for high-power GTO inverter systems. In a parallel drive arrangement, the interface board and the control board are located in the master unit, while the external connections remain the same as those of a single ACV 701 inverter. The master drive requires ABB SNAT620PCB to complete the parallel configuration.

In high-power industrial drives, multiple GTO inverter units are connected in parallel to increase output current and overall power capacity. ABB SNAT620PCB acts as the key connection and signal distribution bridge between these parallel power stages, helping establish efficient, low-impedance connections throughout the main circuit. This arrangement supports coordinated operation of multiple inverter units while maintaining reliable electrical performance during demanding industrial applications.

Besides connecting the parallel main power circuits, ABB SNAT620PCB distributes trigger and pulse control signals from the upper-level control board to the GTO driver boards, ensuring synchronized switching of parallel GTO devices. Uniform signal distribution helps all parallel inverter sections operate together with accurate timing, contributing to balanced load sharing and stable converter performance. Operating from a 24 V DC power supply, ABB SNAT620PCB is designed for environments with temperatures from 0°C to +55°C, storage temperatures from -40°C to +70°C, and an IP00 protection rating.
