Test conditions and notes5

1.All parameters are specified at normal input(F:24Vdc, G:48Vdc), rated load, 25℃ 70% RH ambient.
2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf capacitor.
3.Line regulation is measured from low line to high line at rated load.
4.Load regulation is measured from 10% to 100% rated load.
5.The final equipment must be re-confirm that it still meet 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)

FAQ

Can I use the DPBW03F-05 for a 24V industrial controller that needs a 5V logic rail?

This model is designed for constant-voltage ±5V output with 3W power and a 9-36VDC input range. That makes it suitable where the source falls within 9-36VDC and the control or logic load stays within the 3W output rating.

Is the DPBW03F-05 suitable for embedded electronics inside compact automation equipment?

Its 21.8 × 9.2 × 11.1 mm size and 4.3g weight make it a compact option for tightly packed embedded or control assemblies. The output is constant ±5V at 3W, so it fits small low-power electronics that require a regulated dual 5V rail.

Can this converter be used in low-power IT or communications subassemblies that run from variable control voltages?

It can be considered for low-power electronics when the available input stays within 9-36VDC and the load needs constant ±5V output. The 3W rating is the key sizing limit for small IT, communications, or monitoring subcircuits.

How does the DPBW03F-05 compare with the other DPBW03F models?

In the DPBW03F 3W series, the listed models are DPBW03F-05 with ±5V output and ±300mA output current, DPBW03F-12 with ±12V output and ±125mA output current, and DPBW03F-15 with ±15V output and ±100mA output current. All are constant-voltage units with 9-36VDC input, 21.8 × 9.2 × 11.1 mm dimensions, 4.3g weight, -40°C to +85°C operating temperature, EAC TP TC 020/2011 safety approval, and a 3-year warranty.

Is the DPBW03F-05 appropriate for outdoor or harsh-environment use?

The listed operating temperature range is -40°C to +85°C, which supports wide temperature conditions. However, the supplied specs do not list any IP rating, so the provided data does not confirm suitability for exposed outdoor, wet, or washdown environments.
