Overview

HDR-30-12 is the 12V output model of this series: rated current 2A, rated power 24W, typical efficiency 88%.

HDR-30 is one economical ultra slim 30W DIN rail power supply series, adapt to be installed on TS-35/7.5 or TS-35/15 mounting rails. The body is designed 35mm(2SU) in width, which allows space saving inside the cabinets. The entire series adopts the full range AC input from 85VAC to 264VAC(277VAC operational) and conforms to BS EN/EN61000-3-2, the norm the European Union regulates for harmonic current. HDR-30 is designed with plastic housing that it can effectively prevent user from electric hazards. With working efficiency up to 90%, the entire series can operate at the ambient temperature between -30℃ and 70℃ under air convection. The complete protection functions and relevant certificates for home automations and industrial control apparatus (IEC62368-1, UL508,UL62368-1, BS EN/EN61558-2-16) make HDR-30 a very competitive power supply solution for household and industrial applications.

Test conditions and notes5

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 0.1μF & 47μF parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
5. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

What 12V control panel loads is the HDR-30-12 appropriate for?

At 24W and 2A on a 12V output, the HDR-30-12 suits small-to-medium 12V loads such as relay driver circuits, panel indicator systems, and auxiliary power for 12V communication modules in DIN rail enclosures. Its slim step-shape profile allows tight panel layouts.

How does the HDR-30-12 compare to the other HDR-30 models?

The HDR-30-12 outputs 24W / 2A at 12V. Other 30-class siblings include HDR-30-15 at 30W / 2A (15V), HDR-30-24 at 36W / 1.5A (24V), HDR-30-48 at 36W / 0.75A (48V), and HDR-30-5 at 15W / 3A (5V). All share DIN rail mounting but differ in voltage and wattage.

What certifications does the HDR-30-12 carry?

The HDR-30-12 is approved to UL62368-1, UL508, TUV BS EN/EN61558-2-16 and BS EN/EN61558-1, IEC62368-1, EAC TP TC 004, BSMI CNS15598-1 and BIS IS13252. Isolation class II design and an adjustable DC output (10.8 ~ 13.8V on this model) are standard features across the HDR-30 series.

Is the HDR-30-12 suitable for use in environments with wide temperature swings?

The HDR-30-12 is rated -30°C to +70°C (refer to the derating curve), covering cold and warm industrial panels. Working humidity is 20 ~ 90% RH non-condensing.
