XP Power has added to its DNR range of DIN rail mounted, industrial AC/DC power supplies. The DNR480, a single output 480 W model, offers universal input, accepting voltages in the range 90-264 V a.c. single phase, without the need for switch selection, or 340-575 V a.c. three phase, depending on model.
Both 24 and 48 V d.c. output variants have adjustable outputs from 22,5 to 28,5 V d.c. for the 24 V model and 47,0 to 56,0 V d.c. for the 48 V 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 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 -25 to 70°C. It operates at full power up to 55°C and then derates linearly to a maximum of 60% full power. The power supply is highly efficient, the 24 V d.c. unit rated at 89%, and 90% for the 48 V d.c. variant. DC ON and DC LOW LED status indicators are provided on both models. Additionally, DC OK status signal is available on the 24 V d.c. model. A DC Standby option is also available.
Single phase models measure 175 x 125 x 116 mm. Three phase versions are 150 x 124 x 112 mm.
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.
