FAQ
Which configurations are available? KGT3.35-ZIN and KGT3.50-ZIN use 220 V supplies, with 35 and 50 N·m respectively. The .35S-ZIN and .50S-ZIN versions use 380 V.
What power frequency is required? The specified power frequency is 50 Hz.
Is 120°C the operating ambient temperature? No. It is the thermal-protection threshold. The specified operating ambient range is −20°C to +50°C.
How should the allowable door area be selected? Confirm the required torque, door balance, shaft arrangement and allowable door area for the exact ZIN order code with BISEN.
