XP Power's DNR480 AC/DC power supply

XP Power announced the latest addition to its DNR range of DIN rail-mounted, industrial AC/DC power supplies.

DNR480, a single output 480W model, offers universal input, accepting voltages in the range of 90-264Vac single-phase without requiring switch selection, or 340-575 Vac three-phase, depending on model. Both 24Vdc and 48Vdc output variants have adjustable outputs from 22.5Vdc to 28.5Vdc for the 24V model and 47-56Vdc for the 48V model. Such broad range of adjustment allows the use of the power supply in different configurations. For applications requiring increased power, up to three units may be connected in parallel.

The DNR480 single-phase series also feature input and output connector options. Detachable screw terminals that reduce mean time to repair in customer applications are available as well as standard fixed screw terminals.

The new power supply can operate over a wide range of temperature, from -25C to 70C. It operates at full power up to 55 C and then derates linearly to a maximum of 60 percent full power. The power supply is highly efficient, the 24Vdc unit rated at 89 percent, and 90 percent for the 48Vdc variant. DC ON and DC LOW led status indicators are provided on both models. Moreover, DC OK status signal is available on the 24Vdc model. A DC Standby option is also available. Single-phase models measure 175-by-125-by-116mm, excluding the DIN mount and optional detachable connectors. Three phase versions measure 150-by-124-by-112mm.

DNR480 has EN60950 and UL508 safety approvals that cover IT and industrial equipment respectively. Typical applications include DIN rail-mounted factory automation, light industrial, instrumentation and process control.

A 960W DNR series is due to be released later this year. Meanwhile, the single phase DNR480 is priced at $198.25 for orders of 1,000 units.
