Puls Power Supply Has Three Micro Controllers

Puls has launched its latest Q-series unit, a 40A, three-phase power supply. The QT 40 measures 110 x 124 x 127mm and weighs 1.5kg Two versions of the QT 40 are available - 24V 40A and 48V 20A - both delivering 960W with efficiency of 95.3 per cent. The QT 40 uses three micro controllers to maintain optimum efficiency at all levels of load.

This also makes power sharing easy by allowing multiple units to be mounted side by side on the DIN rail without the need for fan cooling. Other features include near-zero inrush at switch-on, shut-down input with high Mean Time Between Failure (MTBF) values and built-in mains fuses. Puls' Bonus Power overload design provides 150 per cent current reserves for up to 4sec to help start demanding loads.

The QT 40 is suitable for industrial bulk-power applications, such as control systems for large electric motors powering production equipment, conveyors and machine tools. It is also suitable for outdoor applications where the ability to operate at low temperatures is important. Ambient temperatures as low as - 25C can be tolerated without difficulty.
