AKH-0.66/K UL series current transformers, produced by Acrel, are UL-certified and designed for power maintenance and electrical retrofit projects. These transformers feature a compact size, high precision, and strong load capacity. They offer multiple output options, including mV, mA, 5A, and 1A outputs, with rated input currents ranging from 20A to 400A. The rated voltage is AC 0.66kV, and the frequency can be 50-60Hz. They can operate in environments with temperatures between -30°C and +60°C (or up to +70°C for certain models) and altitudes of ≤3000m. These transformers provide excellent performance in power systems, ensuring high accuracy and reliability.
