40A, three-phase power supply is 'smallest on the market'

Puls UK is launching its latest Q-series unit, the super-compact QT 40, which measures only 110 x 124 x 127mm and weighs just 1.5kg. According to Puls, this makes it the smallest 40A, three-phase power supply on the market. First shipments are expected early in 2010.
 
Two versions of the new QT 40 are available, namely 24V 40A and 48V 20A, both delivering 960W with an efficiency of 95.3 per cent.
 
The QT 40's high performance has been achieved by the use of three microcontrollers to maintain optimum efficiency at all levels of load. The high efficiency also makes power sharing easy by allowing multiple units to be mounted side-by-side on the DIN rail without the need for a 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 UK's Bonus Power overload design provides 150 per cent current reserves for up to four seconds 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 useful for outdoor applications where the ability to operate at low temperatures is important; ambient temperatures as low as -25 degrees C can be tolerated without difficulty.
 
Harry Moore, Puls UK's managing director, says: "Because the new QT 40 is so compact and has such a high specification it is 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."
