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 DPBW03G-15 in industrial control equipment that needs a low-power 15V rail?

Yes, it fits low-power industrial control and signal-conditioning circuits that need a constant-voltage ±15V output. This model is rated at 3W and accepts an 18-75VDC input range, so it is better suited to small control sections than higher-load 15V devices.

Is the DPBW03G-15 suitable for embedded analog or instrumentation circuits?

It can be a fit for embedded analog and instrumentation sections that need a compact ±15V constant-voltage supply. The 3W rating and 21.8 x 9.2 x 11.1 mm size make it more appropriate for space-constrained low-power designs than for larger 15V loads.

Can this converter be used in automation panels with wide input variation?

It is intended for applications that need operation across an 18-75VDC input range with a constant ±15V output. That makes it relevant for compact automation electronics where the control circuit is low power and the 3W limit is acceptable.

How does the DPBW03G-15 compare with the other DPBW03G models?

Within the DPBW03G series, all listed models are rated at 3W. The DPBW03G-05 provides ±5V and ±300mA, the DPBW03G-12 provides ±12V and ±125mA, and the DPBW03G-15 provides ±15V and ±100mA.

Is the DPBW03G-15 suitable for outdoor or harsh-temperature environments?

The operating temperature range is -40°C to +85°C, so it is specified for wide-temperature operation. No IP rating is listed in the provided specs, so outdoor or washdown suitability is not established from this data alone.
