Specification
Power Supply:
Supply type: AC transformer supply only
Supply voltage: 115, 230, 400, 525V AC
Housing width: 45mm
Power Consumption: 2VA (approx)
Isolation: Galvanic (without latching)
Voltage Tolerance: ±20%
Voltage Sensing:
Setpoints: The unit is calibrated to trip on the RMS value of the supply voltage (assuming no AC waveform distortion)
Repetitive accuracy: 1%
Hysteresis: 2% (fixed)
Hysteresis relates to the supply voltage
Response:
Response time on trip: 0.1 – 10 seconds (adjustable)
Response time on recovery: 0.1 – 10 seconds (adjustable)
Start-Up delay: 0 – 10 seconds (adjustable)
Latching inhibited during power up.
