40A output model boosts Puls DIN-Rail power supply series

Extending Puls Power’s remote-controlled DIN-Rail power supply family is the 40A output model.

The remote-control feature comes into its own in smart buildings and industrial systems where centralised control of multiple system components is required. It allows system administrators and building automation controllers to switch power supplies on or off via the use of an external signal switch or transistor gate.

The new 24VDC, 40A output QS40.241 DIN-rail power supply joins the CP20.241-V1 24VDC, 20A model and both belong to the Puls Dimension series, which provides solutions for designers and systems integrators requiring powerful and space-saving DIN rail power supplies.

The new QS40.241 DIN-rail power supply has a compact footprint by using the latest synchronous rectification technology, a bridgeless PFC circuit and a number of other proprietary design details. Large power reserves of 150 per cent and built-in large sized output capacitors support the starting of heavy loads such as DC motors or capacitive loads. In many cases this allows the use of a unit from a lower wattage class.

High immunity to transients and power surges, as well as low electromagnetic emissions aid installation in a wide range of environments. The integrated input fuse as well as the near zero input inrush current also help simplify installation and usage.

Power supply status is indicated by a DC-OK relay, a green DC-OK LED and a red overload LED. A large package of international safety approvals makes the QS40.241 suitable for a range of applications.

Key features of the QS40.241 DIN-rail power supply include remote control of output voltage, 100-240VAC wide-range input voltage, width of 125mm and weight of 1.9kg.

The power supply offers 94.6 per cent full load and, says Puls, “excellent partial load efficiencies”. There is 50 per cent BonusPower (1440W for up to 4s), 110A high peak current for 10ms for easy fuse tripping, safe HiccupPlus overload mode, active power factor correction and negligible low input inrush current surge.

Other features listed are full power between -25 degrees C and +60 degrees C, a current sharing feature for parallel use, internal data logging for troubleshooting, DC-OK relay contact and shut-down input.

It is ATEX and IECEx approved and comes with a three-year warranty. Accessories available include a wall mount bracket, buffer unit and a redundancy module

Typical applications for these power supplies include, smart buildings and building automation, industrial and process control, panel-building, test and measurement, instrumentation and communications systems.

Versions are available approved for railway systems and ruggedised for harsh environments.
