Description
DRA-40 is one 40W AC/DC DIN rail power supply, featuring the adjustable output current. Users are
able to easily change the constant output current level, via 1~10Vdc, PWM signal or resistance.
DRA-40 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-40 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 through 70 .℃℃

SAFETY &
EMC
(Note 5)
1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. 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.
5. 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 http://www.meanwell.com)
6. 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.

OUTPUT CURRENT ADJUSTMENT OPERATION
Reference resistance value for output current adjustment (Typical)
Built-in 3 in 1 current adjustment function . Output constant current level can be adjusted by applying 1 ~ 10Vdc, 10V PWM
signal or resistance between DIM+ and DIM-.
Please DO NOT connect "DIM-" to "-V".

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