This Acti9 iPRC product is a surge arrester protecting against overvoltage related to lightning strikes. The DC power supply inputs up to 53V and AC power supply inputs up to 37V. The iPRI surge arrester protects the measuring instrument and PLC "sensor" inputs. It protects for 2 low-current lines without common potential or 4 lines with common reference potential. The input current must not exceed 300mA. The Uc maximum continuous operating voltage in common mode (between neutral and earth) is 130VAC or 185VDC. The Uc maximum continuous operating voltage in differential mode (between pgase and neutral) is 130VAC or 185VAC. The Up Voltage protection level in differential mode (between phase and neutral) is 160V. The Up Voltage protection level in common mode (between phase and earth) is 200V. The Ue rated operational voltage is 130VAC +/- 10%. The product colour is white (RAL9003).The dimensions are (W) 18mm x (H) 90mm x (D) 66mm. The weight is 25g. The degree of protection is IP20 and IP40 in modular enclosure. The operating temperature is -25°C to 60°C. The storage temperature is -40°C to 85°C.
