Electric test bench UHV-316C

automaticmotorthree-phase AC system

Product Introduction:
The UHV-316C comprehensive motor test bench is designed for factory inspection of single-phase and three-phase small and medium-sized asynchronous motors. The bench includes a built-in variable-frequency test power supply and automates standard motor acceptance checks.

Product Characteristics:

• Real-time result display with built-in data storage and print recording for traceable test reports.
• Standard parameter storage for quick comparison and automatic pass/fail judgment.
• Multi-motor simultaneous testing to increase throughput during production inspection.
• High-precision measurements with fast cycle times and strong EMI immunity for reliable on-site testing.
• Windows-based software and modular hardware design for easy configuration, maintenance and calibration.
