Power quality analyzer PQM-750

signalmonitoring3-phase electrical networks

Stationary meter designed to measure and record power supply parameters for compliance with standards and applicable laws, and with the ability to verify preset terms of a power sale/purchase contract. Made in class A. Designed to be mounted on a DIN rail (with the possibility of mounting on a wall in a cabinet). Modular design allows adding new modules to expand the capabilities of the meter. The instrument allows measurements in 50 Hz, 60 Hz and 400 Hz* networks. • Full class A according to IEC 61000-4-30, confirmed by a certificate from an accredited laboratory • Voltage inputs L1, L2, L3, N, E (5 terminals) • L1, L2, L3, N, E currents (5 current transformers) • Built-in current transformers 5 A (optional: 1 A*), possibility of indirect measurements with calculation results for the primary side (optional: version with external current transformers*) • Operation in 50 Hz, 60 Hz networks, operation in 400 Hz networks* • Recording of voltage and current events along with waveforms • Measurement of more than 4,000 parameters • 24-bit analog-to-digital converter • Basic sampling rate of 80 kHz • Conducted emissions monitoring in the 2…150 kHz band • Two LAN ports, including one with the option of powering the meter with PoE (Power over Ethernet) • Power supply 85…264 V AC (120…300 V DC), built-in rechargeable battery • 8 GB memory (microSD card) • USB port for meter updates and data exchange • Two binary inputs, two relay outputs, two RS-485 ports • Relay output to monitoring analyzer operation (Watchdog) • 1-wire input for external temperature sensors • 2.4” touch screen
