This DIN rail power supply from PULS has been manufactured to a high standard, with a compact design that is ideal for installation in an enclosure, and intended for general professional use such as in industrial control, office, communication, and instrumentation equipment.
The PSU is equipped with a host of rich features, including the extremely high efficiency. Large power reserves of 150% and built-in large sized output capacitors support the starting of heavy loads such as DC motors or capacitive loads. This allows the use of a unit from a lower wattage class which saves space and money. Other features include high immunity to transients and power surges, as well as low electromagnetic emission and a DC-OK relay contact.
The QS40.481 unit comes with a manufacturer's three-year warranty and a large international approval package for a variety of applications, making it suitable for nearly every situation.
