Kele PowerTrak Power Monitoring Interface
The PT-9000 Series Power Monitoring Interface monitors numerous power system parameters for local display and/or remote connection to a BAS or other data acquisition equipment. Any three or single-phase 50/60 Hertz electrical system from 120-600V can be monitored by the PT-9000 Series without the need for potential transformers. Higher voltage systems such as 5 kV or 15 kV services can also be monitored using potential transformers. The PT-9000 Series is available for use with 5A or 0.333V current transformers. Options include a current transformer shorting assembly and a digital LCD display.
Furnished in a NEMA 1 hinged-cover enclosure with external mounting feet and conduit knockouts on all sides, the PT-9000 Series is simple to install. Setup of the PT-9000 Series is easily accomplished with a selector switch and DIP switches. A truly unique feature of the PT-9000 Series is its ability to identify and electronically correct wiring problems such as reversed CT polarities or improper phasing of voltages with CT's.
