The GT-AC Series Bidirectional AC Power Supply integrates a programmable AC power source and a regenerative electronic load into a single system. It is designed for automated testing, reliability verification, and aging tests of AC-powered equipment.

Unlike conventional test setups that require separate AC sources and load banks, the GT-AC Series combines both functions in one platform, enabling efficient bidirectional energy flow. During testing, electrical energy generated by the load can be fed back to the grid, significantly reducing energy consumption and heat generation.

Architecture du système

A bidirectional AC power supply system typically integrates both power source and load functions into one platform. The typical architecture includes:

AC Power Source + Regenerative Load + Control System + Power Conversion Modules + Monitoring System = Integrated AC Source & Load Testing Platform

This integrated design reduces equipment footprint, simplifies system deployment, and improves testing efficiency for high-power electrical equipment.

Applications typiques

The GT-AC Series is widely used in testing and aging applications for various AC-powered equipment, including:

  • Systèmes UPS
  • Power inverters
  • AC/DC converters
  • Switching power supplies
  • Circuit breakers
  • Electrical switches
  • Fuses and other power electronic components

It is particularly suitable for high-power laboratory testing platforms, certification testing environments, and automated production testing systems.
