Transformers simplify DC supplies
A
Puls UK product story

Electronic transformers can save users up to 25% of the cost of conventional power convertors.
Puls has come up with a novel concept for generating direct current from a three-phase source.
Devices in the XT40 family of electronic transformers deliver up to 960W from a lightweight, compact package and offer an attractive new method for supplying DC motors and other noncritical loads in industrial systems.
The XT40 family is up to 96% efficient, DIN-rail mounted, measures a miserly 96mm wide and weighs just 1.4kg.
Operating temperature range is - 25 to +60C without derating and offers a 25% "PowerBoost" feature to handle motor startup currents and similar peak loads.
All XT40s meet EN61000-3-2, active input-transient filtering, have a typical power factor of 0.93 and no inrush current surge.
Four models are available offering semiregulated DC outputs of 2V/40A, 36V/26.6A, 48V/20A and 72V/13.3A.
Input voltage can be specified at 400 or 480V.
Front panel mounted LEDs indicate DC OK, transformer shutdown, low input voltage or missing phase and impending thermal cutoff.
Harry Moore, Managing Director of Puls UK comments: "Our new XT series of electronic transformers can save our customers up to 25% of the cost of conventional power convertors".
"They also offer continuing lower cost of ownership as their small size, low weight and very high efficiency reduce costs for cabinets and enclosures, reduce shipping costs, simplify cooling and ventilation requirements and offer real saving in energy consumption".
"Anyone who currently uses conventional transformers or has to supply a power hungry single load will find our XT40 series offers many advantages".
Typical applications include DC motors as used on conveyor belts, manufacturing and logistics systems, industrial drive systems, valves for water distribution and purification systems, electrolytic painting and finishing, welding, heaters and lighting.
The XT40 Series has full international safety agency approvals and quick-connect cable fixings.
All Puls DIN-rail power supplies are available from stock for next day delivery.
