Product Description
The most outstanding features of this Dimension QSeries DIN-rail power supply are the high efficiency and the small size, which are achieved by a synchronous rectification and further novel design details. The QS20.244 is a device for 200-240V non-public mains only. This supports regional applications and offers additional cost and space savings. If a wide-range unit with PFC is preferred, choose the QS20.241. With short-term peak power capability of 150% and built-in large sized output capacitors, these features help start motors, charge capacitors and absorb reverse energy and often allow a unit of a lower wattage class to be used. Diagnostics are easy due to the dry DC-ok contact, a green DC-ok LED and red overload LED. High immunity to transients and power surges as well as low electromagnetic emission makes usage in nearly every environment possible. Unique quick-connect spring-clamp terminals allow a safe and fast installation and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.
