World’s smallest 40Amp, 3-phase din-rail power supply from PULS UK

Two versions of the new QT 40 are available, 24V 40A and 48V 20A, both delivering 960 Watts with record-breaking efficiency of 95.3%.

The QT 40’s high performance has been achieved by PULS’s use of three micro-controllers to maintain optimum efficiency at all levels of load. This extraordinary efficiency 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 despite its diminutive size, built-in mains fuses. PULS’s unique Bonus Power overload design provides 150% current reserves for up to four seconds to help start demanding loads.

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

Harry Moore, PULS UK’s Managing Director said, “Because the new QT 40 is so compact and has such a high specification it’s going to make a big difference to the way engineers design equipment in the future. As they say, the best things come in small packages.”
