DIN-rail supply offers wide output
adjustment
Single-output 480W model joins the DNR range of DIN-rail-mounting industrial AC/DC power supplies.
XP Power has added a new model to its DNR range of DIN-rail-mounting industrial AC/DC power supplies The DNR480, a single output 480W model, offers universal input, accepting voltages in the range 90-264V AC single phase without the need for switch selection, or 340-575V AC three phase, depending on model

Compact single-output 25W AC/DC power supplies are available in three configurations and with a choice of seven different outputs.
DC/DC convertors save PCB space
XP Power has released new additions to its I series of low power isolated DC/DC convertors.
Both 24 and 48V DC output variants have adjustable outputs from 22.5 to 28.5V DC for the 24V model and 47.0 to 56.0V DC 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.
Another important feature of the DNR480 single phase series are the input and output connector options.
Detachable screw terminals, which dramatically reduce MTTR (mean time to repair) in customer applications, as well as standard fixed screw terminals are both available.
The DNR480 is capable of operating over a wide range of temperature, from -25 to +70C.
It operates at full power up to +55C and then derates linearly to a maximum of 60% full power.
The power supply is highly efficient, the 24V DC unit rated at 89%, and 90% for the 48V DC variant.
DC-on and DC-low led status indicators are provided on both models.
Additionally, DC OK status signal is available on the 24V DC model.
A DC standby option is also available.
Single phase models measure 175 x 125 x 116mm, excluding the DIN mount and optional detachable connectors.
Three phase versions are 150 x 124 x 112mm.
The 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.
