Power supplies

Impulse power supplies are designed to be mounted on a DIN bus having a diameter of 35mm, in industrial automation systems, power engineering systems, industrial protection systems and also in security systems. They are characterised by their ergonomic design, high efficiency, broad range of working temperatures (-20°C to 60°C), general-purpose AC supply voltage in full range, and protection systems against short-circuits, overvoltage, overloading and thermal shock. The narrow-type power supplies of the SPX family are used whenever it is required to minimise the amount of space occupied by a power supply on the DIN bus, e.g. in interphone systems or industrial electronics. They provide long-term and stable operation at 5-48V (depending on the type), and are equipped with signalling equipment to indicate correct operation. The power supplies of the SPS family are equipped with 3-phase 4-conductor power supplies and feature constant frequency of impulse operation at 100 kHz. Two-phase operation is also possible. Cooling is carried out open circuit (without forced air circulation).
