Step-down single-phase dry transformers E'lektrotexniceskii zavod OSO, OSM, OSZM, TS, etc.

Single-phase, power transformers of the OSO, OSM general purpose series with a rated voltage of up to 1000V are designed to power control circuits, local lighting, alarm and automation, electric motors.
Decoding of the symbol of transformers of the OSO, OSM series:
O (at the beginning of the designation) – single-phase;
C – dry, natural air cooling;
M – multi-purpose;
O (at the end of the designation) – for local lighting;
OSM1 – modification of the transformer of the OSM series (at the request of the customer).

Model: OSM-0.02, OSM-0.02GW, OSM-0.05, OSM-0.05GW, OSM-0.063, OSM-0.063GW, OSM-0.1, OSM-0.16, OSM-0.25, OSM-0.4, OSM-0.5, OSM-0.63, OSM-1.0, OSM-1.6, OSM-2.5, OSM-3.0, OSM-4.0, OSM-5.0, OSM-6.3, OSM-7.0, OSM-10.0, OSM-12.0, OSM-16.0, OSM-20.0, OSM-25.0, OSM-30.0

• OSO, OSM. Technical specifications.

Single-phase power transformers of the general purpose OSZM series are designed for inclusion in a single-phase AC network of 50 Hz or 60 Hz frequency and low-voltage supply of control circuits, local lighting, alarm and automation, electric motors, for household needs. Transformers are equipped with a protective casing.
Decoding of the symbol of transformers of the OSZM series:
O – single- phase;
C – dry, natural air cooling;
Z – protected;
M is a multi–purpose purpose.

Models: OSZM-2.5, OSZM-3.0, OSZM-4.0, OSZM-5.0, OSZM-6.3, OSZM-7.0, OSZM-10.0, OSZM-12.0, OSZM-16.0, OSZM-20.0, OSZM-25.0, OSZM-30.0
