Transformers of ОСМР series (O – single-phase, C – dry-type, M – multifunctional, P – isolating) rating 0.063…10 kVА, ОСМО series (single-phase, dry-type, multifunctional, O – separating, of general use) rating 0.063…1.0 kVА, ОСМУ series (single-phase, dry-type, multifunctional, У – for power supply to control circuits) rating 0.4…1.0 kVА, with rated voltage not more than 1000 V a. c. of industrial frequency, are intended for power supply to control circuits, local lighting circuits, signaling and automation circuits. Transformers comply with the requirements of STB IEC 61558-1 standard. ОСМО transformers meet IEC 61558-2-1 standard. ОСМУ transformers meet IEC 61558-2-2 and STB IEC 61558-2-6 standards. ОСМР transformers meet IEC 61558-2-4 and STB IEC 61558-2-6 standards. Climatic versions are CT, C and MWDr as to IEC 60721-2-1:2002 standard. Transformers are designed for indoor operation at altitudes above sea level not more than 1000 m (transformers operation is allowed at altitudes up to 3000 m above sea level, but in such a case the load power shall decrease for 2.5 % every 500 m). According to their mobility the transformers are stationary ones. As to installation conditions on worksite, the transformers are incorporated ones. Transformers with the power of up to 0.4 kVA inclusive are to be mounted on a horizontal or vertical plane (for M9 group of mechanical performance); transformers with the power from 0.4 up to 2.5 kVA inclusive are to be mounted on a horizontal plane (for M9 group of mechanical performance); transformers with the power of 0.63 and 1.0 kVA are to be mounted on a vertical plane (for M8 group of mechanical performance); transformers with the power 4.0; 6.3 and 10 kVA are to be mounted on a horizontal plane (for M1 group of mechanical performance). Insulation thermal-endurance class – В as to GOST 8865-93. All the transformer parts made from dielectric materials are resistant against inflammation and flame propagation. The same type transformers of various climatic versions have completely identical electrical parameters and differ by protective coatings only. The corrected sound power level of the transformers both under no-load run and under rated load does not exceed 49 dBA for the transformers with the power of up to 2.5 kVA, and 60 dBA for 4.0; 6.3 and 10 kVA transformers. As to protection against electric-shock hazard the transformers belong to I class in accordance with GOST 12.2.007.0-75 and have IP00 protection degree in accordance with GOST 14254-96. Contact terminals are of IP20 protection degree.
