MEASTEK MCTH3000A Industrial-Grade 3000A Meter | Auto-Level Switching, Anti-EMI Design, -25℃ To 80℃ Extreme Adaptability
1. Super strong current carrying capacity
Maximum current 3000A (DC/RMS), accuracy 0.01%, bandwidth 50kHz, current transfer ratio 1:5000, specially designed for heavy industry and power systems.
2. Multi-level automatic switching
Automatic switching technology covers a wide range of 2000A~3000A measurement, avoiding manual adjustment, improving efficiency, and adapting to ultra-large current scenarios such as power plants and steel smelting.
3. Anti-interference and fast response
Fully isolated design of primary and secondary sides, strong anti-electromagnetic interference ability; response time ≤1μs, follow-up speed ≥100A/μs, accurately capture transient current changes.
4. Harsh environment adaptability
The shell meets the UL94-V0 flame retardant standard, corrosion-resistant and dust-proof design, supports -25℃~+80℃ storage temperature, suitable for outdoor power stations or chemical environments.
5. Highly integrated test solution
It can be used with a mobile multi-channel high-current test platform (optional), supporting solutions with copper busbar/copper cable size > 60.5mm, suitable for high-end fields such as satellite power supply and high-speed train traction system.
