Stationary, modular, comprehensive
Stationary meter designed to measure and record power supply parameters for compliance with standards and applicable laws, and with the ability to verify preset terms of a power sale/purchase contract.
Made in class A. Designed to be mounted on a DIN rail (with the possibility of mounting on a wall in a cabinet). Modular design allows adding new modules to expand the capabilities of the meter. The instrument allows measurements in 50 Hz, 60 Hz and 400 Hz networks.
The PQM-750 can be configured in various ways. Each set of built-in internal modules is a separate sales index for the analyzer. Need help choosing a configuration? Contact our Customer Service.
