Three-phase network analyzer UPA20
Network analyzer UPA20 is a performance metering & monitoring device that provides all of the measurements needed to complete energy efficiency projects and to assure the monitoring of electrical distribution. It is particularly suitable for consumption analysis and control, with an excellent quality/price ratio. With its large backlit multiple-display screen with 4 hot keys, the instrument is easy to use. Furthermore, it is provided with a correction function for CT wiring errors.
The instrument can be equipped with additional modules for RS485 communication and additional digital inputs/outputs can be used to increase its range of functionality. The instrument is compliant with IEC 61557-12, the reference standard for PMDs
(Performance Metering & monitoring Devices).
