Product Introduction
Product Features
Built-in resolver excitation power supply, can measure the angle and voltage output by single and dual channel resolver
Supports optional self-aligning machine angle measurement function
Performance can replace 8810A and other equipment imported from the United States
Suitable for areas with high angle accuracy requirements such as resolver decoding and motor driver testing
SmartAPI is a newly developed high-precision angular position indicator with completely independent intellectual property rights. It is based on MIAIXI Measurement & Control's unique resolver analyzer architecture and has performance beyond that of the 8810AH. Even at a high frequency of 10kHz, it still has a decoding accuracy of 10″. The high-frequency angle measurement accuracy is more than 2 times that of 8810AH, and the voltage measurement accuracy is more than 30 times. The optional phase angle voltmeter function can complete angle, phase, and voltage measurements at the same time.
