Product Overview
The GT-DC Series Bidirectional DC Power Supply is an integrated DC source and regenerative load system designed for automated testing, aging tests, and reliability verification of DC power equipment. By combining a programmable DC power source and a regenerative electronic load in a single platform, the system enables efficient bidirectional energy flow and high-precision power testing.
Compared with traditional testing setups that require separate DC power supplies and load banks, the GT-DC Series integrates both functions into one system, significantly reducing equipment footprint, simplifying system configuration, and improving overall testing efficiency. During operation, the regenerative load feeds energy back to the grid, minimizing energy waste and heat generation.
With full digital DSP control across all power conversion stages, the GT-DC Series provides high stability, fast dynamic response, and accurate voltage regulation. Its modular architecture supports flexible system expansion and hot-swap maintenance without interrupting operation, making it suitable for large-scale testing platforms and automated production lines.
The GT-DC Series is widely used for the testing and aging of UPS systems, power inverters, converters, and other DC power supply equipment, as well as power electronic components such as circuit breakers, switches, and fuses.
System Architecture
A bidirectional DC power supply system typically integrates both DC source and load testing capabilities into a unified platform. The typical system structure includes:
DC Power Source + Regenerative DC Load + Power Conversion Modules + Control System + Monitoring System= Integrated DC Source & Load Testing Platform
This integrated design enables efficient power circulation, reduces energy consumption during testing, and improves system reliability for high-power testing environments.
Typical Applications
The GT-AC Series is widely used in testing and aging applications for various AC-powered equipment, The GT-DC Series is suitable for various DC power testing scenarios, including:
- UPS DC bus testing
- Inverter and converter testing
- Energy storage system testing
- Power supply aging tests
- Power electronics component verification
- Automated production line testing
It is particularly ideal for laboratories, certification testing facilities, and industrial testing systems requiring high-power DC source and load capabilities.
