DRA-40 40W Single Output Switching Power Supply LPS ■ Features Universal AC input / Full range Protections: Short circuit / Overload / Over voltage Can be installed on DIN rail TS-35/7.5 or 15 Output Voltage adjustable through internal potentiometer Output Current adjustable through external 1~10Vdc, PWM series Bauar t gepruft Sicherheit egel ma ge od o s be wac g www.tuv.com ID 2000000000 ■ Applications Machine vision inspection system Plant cultivation system signal or resistance Cooling by free air convection Pass LPS LED indicator for power on 100% full load burn-in test 3 years warranty ■ 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 ℃ . ■ Model Encoding DRA - 40 - 12 Output voltage Output wattage Series name File Name:DRA-40-SPEC 2015-06-11 DRA-40 40W Single Output Switching Power Supply series SPECIFICATION MODEL OUTPUT DRA-40-12 DRA-40-24 DC VOLTAGE 12V 24V CONSTANT CURRENT REGION 3~12V 3~24V RATED CURRENT 3.34A 1.7A CURRENT RANGE 0 ~ 3.34A 0 ~ 1.7A RATED POWER 40.08W 40.8W RIPPLE & NOISE (max.)

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.
