Frequently Asked Questions

What is the Mean Well DRC-40B designed for?

The Mean Well DRC-40B is a 40.02W DIN rail power supply intended for security and other control-panel applications that need a 27.6V DC output. Its UPS-oriented feature set, including battery low protection and AC OK or battery low alarm signaling, makes it suited to systems where power status monitoring matters.

What output does the DRC-40B provide?

This model provides a rated 27.6V DC output with a rated current of 0.95A, for a total power rating of 40.02W. The output voltage is adjustable within ±8.6% of the rated value.

What protection features are included on the DRC-40B?

The DRC-40B includes protection for short circuit, overload, and over-voltage conditions. It also includes battery low protection and battery reverse polarity protection by fuse, which helps distinguish it from a basic DIN rail power supply.

What input range does the Mean Well DRC-40B support?

The unit accepts a universal input range of 90 to 264VAC, and it also supports 127 to 370VDC input. This wide range makes it practical for use across varied mains power environments without needing a region-specific version.

Is the DRC-40B suitable for demanding industrial or enclosure environments?

The DRC-40B is rated for operation from -30°C to +70°C and uses free air convection cooling. It is also designed for DIN rail TS-35/7.5 or 15 mounting, which fits typical panel and enclosure environments where compact DIN rail hardware is preferred.

What certifications and compliance standards does the DRC-40B meet?

This model is approved to UL62368-1, TUV BS EN/EN62368-1, EAC TP TC 004, and AS/NZS 60950.1 safety standards. For EMC, it meets EN55032 Class B and related EN61000 immunity and harmonic standards listed in the specification.
