IEC 60691 Intelligent Thermal Fuse Tester 0-300A Endurance & Overload Test Equipment
Product Description
The Intelligent Thermal Fuse Tester is a specialized instrument designed for testing the performance of small fuses, including fuse blowing time and current measurement. It complies with GB/T 9364.1-2015, GB 9364.3-2018, GB/T 9816.1-2023 Clause 10.4, and IEC 60691-2023 standards for fuse, endurance, and overload testing requirements. Equipped with a 7-inch touch screen for display and parameter setting, and controlled by an ARM processor, this programmable tester delivers test currents up to 300A. Featuring smart operation, high precision, and reliable safety, it is an ideal solution for fuse testing applications.
Features
Advanced DC power supply design with zero-voltage full-bridge/half-bridge topology and PWM control for fast dynamic response and high accuracy in voltage and current output.
Programmable constant voltage and constant current modes.
Supports four test modes: Fuse Blowing Test (M1), Endurance Test (M2), Step Test (M3), and Overload Test (M4).
Ultra-fast response time in the millisecond range.
Multiple protection functions (overvoltage, overcurrent, etc.), with automatic cut-off and audible/visual alarm.
High conversion efficiency with ZVZCS switching technology.
Real-time data recording for easy review and analysis.
Smooth and accurate switching between constant voltage and constant current with no overshoot.
Large 7-inch touch screen interface with full digital control for user-friendly operation.
