PLA33 power line analyser s i m p l y Power line analyser PLA33 is a modern device for multifunction monitoring of main electrical parameters in three­phase network. Device measures parameters according to norm IEC 61000­4­30 and it is ideal for very precise power management. Internal memory and communication interface define the PLA33 being used as power monitoring recorder or part of SCADA systems. • 4 quadrant continual measurement • monitoring of U in every phase and phase­phase • monitoring of I in every phase • calculated current in neutral wire • system frequency • THD U and THD I • odd harmonics of U and I till 19th (L1, L2, L3) • power factor (L1) and cosφ (L1, L2, L3) • P+/­, Q+/­, S (L1, L2, L3, ∑) • Eactive+/­, Ereactive+/­ (L1, L2, L3, ∑) • internal current transformers ICT • measurement according the standard IEC 61000­4­30 • measuring phase­phase voltage from 0 ... 520 VAC • auxiliary power supply • memory for recording of maximums / minimums • memory for recording of 20 power cut events • internal real­time clock • communication interface RS485 with Modbus RTU protocol • internal memory 512MB for measured parameters recording • minimum internal memory sampling period 60s (AVG value) • two independent digital input / output BMR trading, Horní lán 17, 779 00 Olomouc, Czech Republic, tel.: +420 778 066 566, export@bmr­trading.com, www.bmr­trading.com
