Whirlwind now offers a monitoring solution for projects that need accurate and reliable real-time power utilization feedback. The PL-PM1 power meter is a 2-RU rack-mount unit that connects to your Whirlwind distro by means of a Eurostyle connector on the rear of the unit, and displays the voltage on a bright and easy-to-read display – even in direct sunlight – on the front of the unit. Far from being just a simple voltmeter, however, the PL-PM1 also has a second set of readouts for reading amperage usage across all three hot legs, allowing you to monitor current across the entire system in real time. Additional displays show the AC frequency, neutral-to-ground voltage and amperage on the neutral leg.
