Din Rail Switching Power Supply SPEC




 
DRA series is AC/DC converter DIN rail switching power supply, featuring the adjustable output current. Users are able to easily change to constant output current level, via1-10VDC, PWM signal or resistance. DRA series led driver can be mounted on DIN rail TS-35/7.5 or 15; in addition, the width of the unit is only 40mm that it is well suitable for the installation in a limited spacing. DRA series din ral power supply accepts the universal AC input between 90VAC and 264VAC; the efficiency is up to 87% that the entire series can operate, under free air convection, from -30ºC through 70ºC.

Meanwell DRA series din rail power supply stabilized 40 to 60 watts, mounting on DIN rail without tools thanks to rail hook with spring washer. The connections are made via screw terminals. These power supplies are protected against overload, overvoltage, overheating and short circuit.

Meanwell is a leading standard switching power supply manufacturers in the world. Kulon Electronics is the biggest meanwell agent in the China, our product lines include AC/DC switching power suppliers, DC/DC converters, DC/AC inverters and battery chargers. "Total quality assurance and customer satisfaction' are the central goals of our company.
How to choose a suitable Switching Power Supply?
A.To increase the reliability of the S.P.S., we suggest users choose a unit that has a rating of 30% more power than actual need. 
For example, if the system needs a 100W source, we suggest that users choose a S.P.S. with 130W of output power or more. By doing this, you can effectively boost the reliability of the S.P.S. in your system

B. Choosing functions based on your application:
1. Protection function: Over Voltage Protection (OVP), Over Temperature Protection (OVP), Over Load Protection (OLP), and etc.
2. Application function: Signaling Function (Power Good, Power Fail), Remote Control, Remote Sensing, and etc.
3. Special function: Power Factor Correction (PFC), Uninterruptible Power Supply (UPS) function.

C. Make sure that the model qualifies for the safety standards and EMC regulations you need.
1.Apparent Power=Input Voltage x Input Current (VA) 
2.Real Power= Input Voltage x Input Current x Power Factor (W) 

From the environment friendly point, the electric power plant needs to generate a power which is higher than apparent power in order to steadily provide electricity to the market. The real usage of electricity should be defined by real power. Assuming the power factor is 0.5, the power plant needs to produce more than 2VA to satisfy 1W real power. On the contrary, if the power factor is 0.95, the power plant only needs to generate more than 1.06VA to provide 1W real power need. It will be more effective.
