Cost Benefit Real Life Examples
Voltage Drops are a hidden cost for many industries. While the impact is real, the fact that voltage drops are the reason is not always easily identified. In the industrial sector, voltage drops can account for an added $60 of added cost per kilowatt. This comes in the form of mechanical failure, delays, or unplanned downtime. Additionally, a voltage drop could require a technician to perform maintenance in order to restore process function and therefore adding both additional cost in labor and downtime.
Why the PSQI Coil-Lock? A low cost, easy to install and highly-reliable motor starter solenoid coil hold-in-device for voltage-dip ride-through protection during electric service system upsets.
