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.

5. INPUT INRUSH CURRENT
An active inrush current circuitry (NTC and fixed resistor which are bypassed by an IGBT after the inrush is completed)
limits the input inrush current after turn-on of the input voltage.
The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on.

Instructions:
a) Use appropriate copper cables that are designed for minimum
operating temperatures of:
60°C for ambient up to 45°C and
75°C for ambient up to 60°C minimum
90°C for ambient up to 70°C minimum.
b)Follow national installation codes and installation regulations!
c) Ensure that all strands of a stranded wire enter the terminal
connection!
d)Do not use the unit without PE connection.
e) Unused terminal compartments should be securely tightened.
f) Ferrules are allowed.
Fig. 12-1 Connecting a wire
1. Insert the wire 2. Close the lever
To disconnect wire:
reverse the procedure
Daisy Chaining of Outputs:
Daisy chaining (jumping from one power supply output to the next) is allowed as long as the average output current
through one terminal pin does not exceed 25A. If the current is higher, use a separate distribution terminal block as
shown in Fig. 12-3.
