PLA34 power quality analyser panel mounting quality analyser according IEC 61000­4­30 class S The power quality analyser PLA34 is designed according to norm EN 61000­4­30 class S, with three voltage and four current inputs for measurement of electrical parameters in LV and MV systems. PLA34 is built on a 32 bit RISC processor that provides sufficient processing capabilities for real­time measurement and calculation of all parameters & values. Continuous sampling of the voltage and current inputs at 40 kHz, guarantees the highest accuracy. The PLA34 is the instrument for power quality monitoring according to EN 50160 of the incoming energy supply side as well as on the consumer side in order to find and analyse the root cause of network problems. • Measurement of power quality according to the EN 61000­4­30, class S • Continuous sampling of voltage and current inputs at 40 kHz • 4 voltage measuring inputs and 4 current measuring inputs • Fourier analysis from 1st to 65th harmonics of U L­N, U L­L, I, P (+/­) and Q (L/C) • Harmonics and inter­harmonics measurement of U L­N, U L­L, I according to EN 61000­4­7 • Short term and long term flicker measurement according to the EN 61000­4­15 • Detection of transients > 25 µs • Detection of events > 10 ms • Measured data logger, event and transient memory 1GB flash • RS485, Ethernet, USB • 2 built in digital inputs / outputs • Additional digital and analogue outputs and inputs via RS485 expansion module BMR trading, Horní lán 17, 779 00 Olomouc, Czech Republic, tel.: +420 778 066 566, export@bmr­trading.com, www.bmr­trading.com
