Power Quality Solutions, Inc.

Momentary voltage drops are responsible for billions of dollars per year in lost revenues. These revenues lost effect tremendously the Manufacturing and Process Industries. PQSI’s Coil-Lock, hold-in-device, keeps motors and other critical process control elements engaged during voltage drops and dips.

PQSI works with each company on an individual, customized level and we always support doing what is right every time, every customer.

The Coil-Lock is not time-based, therefore it maintains operation during sag events. Voltage can drop up to 75% and the Coil-Lock will keep contacts closed and processes and motors running with only 25% of remaining voltage.

How It Works

The Coil-Lock allows critical power processes and elements to stay active during power disturbances; thus, keeping relays, contactors, and motor starters engaged.
