ABSOPULSE Electronics has released the HTP 3K5-3U4 series of rugged AC-DC power supplies with 3-phase, high voltage ac-inputs. The 3500W power supplies are suitable for heavy duty applications including servo drives, factory automation, industrial machinery, and equipment.

The power supplies operate from a 480Vac (430-530V) 3-phase line input and deliver any single output voltage between 24V and 600Vdc. A DC-input version which accepts any voltage between 500V and 800Vdc, is also available.

The units are built with heavy-duty internal power modules. A built-in redundancy diode separates the internal modules and also allows for a number of units to be connected in parallel to achieve higher output power, N+1 redundancy. The output redundancy diode also makes the unit suitable for battery charging applications.
