Fluke 1743 Three Phase Power Quality Logger

 Fluke 1743 Power Quality Logger

Assess power quality and conduct long-term studies with ease
Compact and rugged, the Fluke 1743 three-phase power quality loggers are everyday instruments for technicians who troubleshoot and analyze power distribution systems. Capable of simultaneously logging up to 500 parameters for up to 85 days and capturing events, the Fluke 1740 Series helps uncover intermittent and hard-to-find power quality issues.

Plug and play
All three 1740 Series loggers feature easy plug and play setup, for immediate use. The current probes are connected to the logger with a single plug. The instrument automatically detects, scales, and powers the probes using line power from the measured voltages. Once it is connected, logging begins with the touch of a single button!

Electrical shock protection
The Fluke 1740 loggers feature double insulated enclosures and accessories to help prevent electrical shock when coming into contact with blanket bus bars, terminals, or cables. They are also designed to meet the stringent safety standards for use in 600 V CAT III and 300 V CAT IV environments

Measure all power quality and power parameters
For basic power logging, the Fluke 1743 captures all relevant power parameters.


Features:

• Plug and play:
  • Setup in minutes with automatic current probe detection and powering
• Installs inside the cabinet:
  • Compact, fully insulated housing and accessories fit easily in tight spaces, next to live power
• Monitors power for the long-term:
