ENERAL
The most outstanding features of this Dimension Q-
Series power supply are the high efficiency and the
small size, which are achieved by a synchronous
rectification and further novel design details.
With short-term power capability of 150% and built-
in large sized output capacitors, these features help
start motors, charge capacitors and absorb reverse
energy. A wide range input voltage design and a
negligible low input inrush current make installation
and usage simple. Diagnostics are easy due to the
DC-ok relay, a green DC-ok and a red overload LED.
Unique quick-connect spring-clamp terminals allow a
safe and fast installation. Many global approvals
make this unit suitable for nearly every situation.

For pulse load compatibility, following rules must be met: The pulse power demand must be below 150% of the nominal power. The duration of the pulse power must be shorter than the allowed Bonus Time.
