Test conditions and notes5

1.All parameters are specified at normal input(L:5Vdc, M:12Vdc, N:24Vdc, O: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 DPRN01O-12 in a 48V-class industrial system that needs a ±12V rail?

Yes, this model is intended for low-power constant-voltage conversion when the input is in the 45.6 ~ 52.8Vdc range. It provides ±12V output at 1W with ±0 ~ 42mA output current, which makes it suitable for light-duty control, interface, or analog sections.

Is the DPRN01O-12 appropriate for compact embedded or automation boards on 48V equipment?

It can be used where a small embedded or automation board needs a ±12V rail from a 45.6 ~ 52.8Vdc source. The 19.6 × 7.1 × 10.14 mm size supports compact layouts, while the 1W rating keeps it in the low-power category.

Can this converter power low-power instrumentation or interface circuitry in telecom or control hardware?

Yes, if the target circuitry needs a constant-voltage ±12V output and stays within 1W and ±0 ~ 42mA output current. It is a better match for small instrumentation or interface stages than for heavier subsystem loads.

Is the DPRN01O-12 suitable for outdoor enclosures or exposed installations?

No IP rating is listed in the provided specifications, so it should be treated as a protected internal component rather than an exposed outdoor product. The operating temperature range is -40°C to +90°C.

How does the DPRN01O-12 compare with the DPRN01O-15?

Both are 1W models in the DPRN01O series. The DPRN01O-12 provides ±12V output at ±0 ~ 42mA, while the DPRN01O-15 provides ±15V output at ±0 ~ 34mA.
