Test conditions and notes6

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.

FAQ

Can I use the DRA-40-24 in a 24V industrial automation or PLC cabinet?

Yes. The DRA-40-24 provides 24V DC at up to 1.7A with 40.8W output, which fits 24V cabinet loads that stay within those ratings. Its DIN rail design and 100.0 × 90.0 × 40.0 mm housing are suited to control enclosure installation.

Is the DRA-40-24 appropriate for 24V building management control panels?

It can be a fit for building management panels that use a 24V DC bus and have lower current demand. With 1.7A output and 40.8W power, it is better suited to lighter 24V control loads than larger field power loads. Buyers should size it to the actual 24V current requirement of the cabinet.

Can this power supply be used where output adjustment is needed in a control enclosure?

Yes. The DRA-40-24 supports output current adjustment from 10% to 100% by 1-10VDC, PWM, or resistance, and the output voltage is adjustable. That makes it useful in 24V control cabinet applications where adjustable output behavior is specified.

Is the DRA-40-24 meant for use inside a control cabinet rather than exposed conditions?

Yes. This is a DIN rail power supply intended for enclosure-based use, with an operating temperature range of -30°C to +70°C. The listed specs do not describe an outdoor-rated standalone housing, so it is best aligned with protected control cabinet environments.

How does the DRA-40-24 compare with the other DRA series models?

The DRA-40-24 is 40.8W at 24V and 1.7A. The related models are DRA-40-12 at 40.08W, 12V, 3.34A, DRA-60-12 at 60W, 12V, 5A, and DRA-60-24 at 60W, 24V, 2.5A. The family differences come down to output voltage, output current, and power level.
