Puls has closed a gap in its line-up of DIN rail power supplies with two 48V variants.

Puls has closed a gap in its line-up of DIN rail power supplies: the MiniLine model ML100 is now available as a 48V variant, and the SilverLine 240W power supply family SL10 will be extended with a 48V variant with PFC choke The proven quality of Puls power supplies, previously available for 48V applications in the 50 and 480W ranges, is now accessible to users with systems in the medium range (100 or 240W)

In contrast to the more common low voltage DC 24V, the variety of power supplies with 48V output available on the market is much smaller.

Puls has reacted to this and widened the product range of DIN rail power supplies in this sector.

The "power cube" ML100, with 100W output power and dimensions of 73 x 75 x 103mm, is one of the most compact power supplies in the market.

This model has now has been supplemented with the 48V variant ML100.105.

The advantages of the 24V original, such as the high efficiency of 91% and the generous overload behaviour, have remained intact.

The input stage of the ML100.105 has been equipped with an "auto-select" input, an uncommon feature in this power range.

The power supply recognises the connected input voltage automatically, and is therefore instantly suitable for worldwide use.

The auto-select input also offers much better efficiency than a common wide-range solution.

Several ML100.105 may be operated in parallel for increased output power or redundancy applications.

The user can switch the output characteristic with a front jumper from a flat characteristic (single use) to a soft characteristic (parallel use) for this purpose.

The soft characteristic causes a balanced load distribution between the individual power supplies.

For redundant applications Puls decouples the power supply outputs with the redundancy module SLR01.

This module prevents currents from other power supplies from entering the output stage of the defective unit while the rest of the system is still provided with DC power.

The SLR01 module also signals the failure of a power supply via a signal terminal.

In the higher power segment, the 48V Puls product range has been extended by the 240W power supply SL10.106.

This new variant of the SL10 features a dampened input stage that releases fewer harmonics into the mains.

Therefore the supply stays well within the limits of the harmonics standard EN61000-3-2.

Apart from a 115/230V AC manual-select input for worldwide use, the SL10.106, like almost any other Puls power supply, features the proven Puls Overload Design.

It will therefore not switch off even under a persistent overload (no hiccup), but will provide up to 1.5 times the rated current at reduced output voltage.

This helps to start even heavy loads like motors or DC/DC convertors with ease.
