K8DS-PZ

Features

Slim-line three-phase voltage, asymmetry and phase-sequence phase-loss protection

K8DS-PZ monitors undervoltages, overvoltages, voltage asymmetry, phase sequence and phase loss for 3-phases, 3-wire monitoring in one unit.

Worldwide power specifications supported by one unitFront rotary switches allow for easy and accurate configurationReset method: automaticLED indicators: Power (Green), Relay output (Yellow), Alarm output (Red)Robust operating temperature: -20 to 60 ⁰C

17.5 mm (w) bodyGreater resistance to inverter noiseWorld-wide power specifications supported by one unit

Rated input voltage

K8DS-PZ1

3-phase, 3-wire mode: 200, 220, 230, 240 VAC

K8DS-PZ2

3-phase, 3-wire mode: 380, 400, 415, 480 VAC

Operation (overvoltage or undervoltage)

Operating value setting range

Overvoltage/undervoltage: 2% to 30% of rated input voltage

Operating value

100% operation at set value

Asymmetry operation (ASY.)

Operating value setting range

Asymmetry rate: 5% to 22%

Operating value

100% operation at set value

Asymmetry operating value = rated input voltage x asymmetry set value [%]

The asymmetry operation will function when the difference between the highest and lowest voltage phases equals or exceeds the asymmetry operating value

Reset (HYS.)

Hysteresis

5% of operating value (fixed)
