Description:
Transformers TLS 1250/6/0.4 with cast insulation are designed to convert electric power in alternating current networks with a frequency of 50 Hz directly at consumers. Operation of these devices requires compliance with certain conditions, including ambient temperature in the range from -60 to +40 °C, absence of explosive atmosphere and low dust concentration. The key advantages of TLS transformers are low noise level, resistance to voltage fluctuations and high level of fire safety.
