The tiny PQube is a superb Energy and Power Quality recorder. Compact and cost-effective, it has 4GB of memory. It's packed with more features than any other monitor available. No software required - if you can use a digital camera, you can use a PQube.

Need the simplest possible Power Quality sensor? The PQ1 gives you AC-in, relay-contact-out simplicity. Your software will know every time there is a sag, dip, swell, or impulse on the mains. Ultra Low Cost.

PSL's Industrial Power Corruptors generate bad quality power, reliably and repeatedly. Use an IPC to test your sensitive design and fix any problems that you find. Then you'll be confident that your system will work reliably, anywhere in the world.
