Electrical power supply transformer - 8 - 24 V, max. 63 VA | 4AC3
The Siemens transformers for permanent loads provide a safety extra low-voltage or SELV for the control circuits supply, switching relays and insta contractors in continuous operatons as an AC voltage or current supply for 8, 12 or 24V AC. Although each unit is able to transform up to 63 VA, the Siemens transformers for extra load contains a PTC resistor that prevents short-circuits or moderate overloads. The PTC resistor must be switch off for about 30 minutes in case of a disconnection. Turning off the resistor allows it to cool down. One of the highest demands in the transformer manufacturing industry is maintaining a 10% difference between the non-loaded output voltage and the output voltage loaded with the rated load for transformers for permanent loading. Due to the innovative design devised by Siemens, this product meets even the highest of demands at the same time keeping its quality and efficiency. Siemens lives up to its image as a leading brand in producing transformers along with other products that the market has highly benefited from.
