Electrical Power Meters

Trinity Energy Systems offers Electrical Power Meters, Power PRO. This is a true-RMS electrical power meter for use in three phase 3-/ 4-wire electrical systems. This measures the phase voltages, currents, PF, Hz, system kVA, system kW, system kVAr, active energy (kWh), Apparent Energy (kVAh) and reactive energy (kVARh). The various parameters measured are sequentially displayed on a 16 x 1 STN LC display. The CT ratio (primary) can be programmed at site using the front membrane keypad. The meter uses state of the art digital signal processing (DSP) circuitry to achieve very high accuracy measurement of true RMS value of all above parameters. The meter accuracy is class 1.0s for all parameters including kWh. Features: multi parameter monitoring; measures, all important electrical values; all parameters with default accuracy class 1.0s; compact 96 x 96 DIN enclosure; also available in 0.5s accuracy, with large 16 x 4 display; micro-controller based; optional RS-485 port for centralised SCADA, including software; and optional alarm/trip output, field programmable for any parameter including MD (maximum demand). Technical specifications: voltage inputs - 3-/4-wire of a 110/230/415 V electrical system (field configurable); current inputs - 1/5 A; C T secondaries from two/three phases (field configurable); parameters displayed - three voltages, three currents, three power factors, Hz, kVA, kW, kVAr, kWh, kVAh, kVARh, demand, maximum demand; display: 16 x 1 LC display (16 x 4 optionally available); load range - 120% to 0.4% of rated CT primary; operating PF - zero lag to unity to zero lead; and size - panel cutout: 92 x 92 mm; bezel: 96 x 96 mm.
