Q-Series

1. GENERAL DESCRIPTION

The most outstanding features of this Dimension Q­Series 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 built­in 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.
