FAIL-SAFE transformer, control- and isolating transformer
FST 100/23 - Discontinued items – not for new applications
Characteristics
Benefits
› With integrated FAIL-SAFE protection
› High power density due to a compact construction design
› Very good switch-on behaviour thanks to reduced starting currents
› May be operated at 50 - 60 Hz
› Very good corrosion protection and low noise thanks to BLOCK IMPEX vacuum impregnation
› Primary side for input voltage 230 Vac and 400 Vac
› 100 VA and 160 VA versions for mounting with integrated DIN rail mounting in compliance with DIN 50022
