Electric power sensor PQ1

DIN rail

Connect PQ1 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. Ultra-low cost, high-value. 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 AC in, Relay out Connect PQ1 inputs to the AC line that feeds your system, and connect its relay contacts to your control computer’s digital inputs PQ1 uses Voltage dips Voltage swells Interruptions High frequency impulses / transients, 500 nanosecond response time Front-panel LEDs and switches for simple installation and monitoring Three relay contact outputs
