The most outstanding features of the 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.
