GENERAL DESCRIPTION
The most outstanding features of this Dimension Q-
Series 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.
