MEAN WELL DRA-60-12 Single Output Switching Power Supply Instruction Manual

DRA-60 is one 60W AC/DC DIN rai l power supply, featuring the adjustable output current. Users are able to easi ly change the constant output current level, via 1 ~ 1 0Vdc, PWM signal or resistance. DRA-60 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 suited for the installation in a limited spacing. DRA-60 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 -30°C through 70°C.

NOTE	All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor. Tolerance : includes set up tolerance, line regulation and load regulation. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf ) Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is recommended. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

Using the current adjustment function can not adjust the output current to 0A. Please refer to the connection method below to adjust the output
current to 0A.

Driving Methods Of Applications

The power supply may either work in “constant voltage mode or constant current mode”

In the constant current region, the highest voltage at the output of the driver
depends on the configuration of the end systems.
