Fluke 1775 Three-Phase Power Quality Analyser

The 1775 Three Phase Power Quality Analyzer is a rugged, portable device for troubleshooting power quality. The compact size and power supply from the measurement line makes it a versatile tool for live measurements and long-term logging.

Key Features:

• 3-Phase voltage measurement inputs with reference to N and N-to-PE measurement
• 4 current measurement inputs for 3-phases and Neutral
• 2 auxiliary measurement inputs for measurements of non-electrical units: temperature,
humidity, light intensity
• Power supply 100 V ac to 600 V ac and 100 V dc to 660 V dc with safety sockets for
powering from measurement line
• 7-inch display with capacitive touch
• GPS time synchronization
• USB interfaces: Type A for Flash drives and USB-C for wired connection to PC and power
supply
• Slot for Wi-Fi/BLE module
• Slot for LTE-4G module
• Ethernet 1000Base-T
• User-accessible micro SD slot for flash memory expansion
