Power Standards Lab - PQ1 Power Quality Relay

Availability: In stock


Quick Overview

Designing in Power Standards Lab's (PSL) PQ1 Power Quality Relay is simple: Just connect its inputs to the AC line that feeds your system, and connect its relay contacts to your control computer's digital inputs.
Your software will know every time there is a sag, dip, swell, or impulse on the mains.

Power Standards Lab's (PSL) PQ1 Power Quality Relay has the simplest possible interface: AC power in, normally-closed relay contacts out. DIN-rail mount or chassis-mount. Pre-programmed with standard thresholds: SEMI F47, ITIC, CBEMA, IEC, ZA, MIL-STD, and more!


Automatically adapts to 50 Hz, 60 Hz, and 400 Hz, at any standard world-wide voltage: 100V, 110V, 120V, 200V, 208V, 220V, 230V or 240V (or higher with external step-down transformer). Comes pre-programmed to industry-standard thresholds.

  • Voltage sags
  • Voltage swells
  • Interruptions
  • High frequency impulses/transients, 500 nanosecond responce time
  • Front panel LED's and switches for simplest installation
  • Three relay contact outputs
  • No computer required. No software required

Easy installation: just connect AC power. Use the PQ1's LED display, or connect the PQ1's relay outputs to your system or an alarm bell.
