Product Description:
space
Panel-mounted power and energy meter with a large, three-row LED display integrates all the measuring functions required for power management in substations, factories, process plants and office buildings. PR300 users are interested in allocation of energy costs, conservation of energy and overall electrical system reliability. Other benefits of using the PR300 are reduction of panel space and wiring due to multifunctional capability, and access to LAN for centralized monitoring of power useage and demand.
