Single-phase dry-type transformers (OS-series)
Transformers of OS-series (З) – single-phase, dry-type(З-with housing) voltage transformers, designed to power electrical equipment, electrical control systems, alarm, control circuits, local lighting, etc. OS-series transformers are used for operation in mains with voltage up to 660 V and a frequency of 50 Hz. Power range is from 6.3 to 40 kVA.
