Overview

DRC-180B is the CH1: 27.6V; CH2: 27.6V output model of this series: rated current CH1: 4.5A; CH2: 2A (Battery charger), rated power 179.4W, typical efficiency 90%.

DRC-180 is a 180W AC/DC DIN rail type security power supply series. In addition to the primary output, there is a charger output with a smaller rated current, enabling the backup power supply application the security access systems require. DRC-180 accepts the universal input between 90VAC and 264VAC, and supplies 13.8VDC and 27.6VDC at output, respectively. With the efficiency up to 90%, it can operate with air convection cooling under -20℃ through 70℃. In addition to the key protection features such as overload protection,over voltage protection, battery low cut off, and battery reverse polarity protection (by fuse), the alarm signal for AC OK and battery low signaling is provided, via relay contact output, to facilitate the system design.

Test conditions and notes8

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. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to increase of the set up time.
5. Please refer to suggested Application 2.(2)、(3) in page 4.
6. 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).
7. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets 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 )
8.The battery voltage is lower than the CUTOFF voltage and cannot perform AC reset charging.

FAQ

What is the Mean Well DRC-180B designed for?

The DRC-180B is a DIN rail AC/DC power supply with built-in UPS functionality for systems that need regulated 27.6V DC output and battery backup support. It is commonly suited to security and control applications where continuity during AC power loss is important.

What are the main output ratings of the DRC-180B?

This model is rated for 179.4W total output power with a nominal 27.6V DC output and 4.5A rated current. The CH1 output voltage is also adjustable, with the product data listing an adjustment range of 24V to 29V.

Does the DRC-180B include UPS and alarm functions?

Yes. This model includes built-in UPS capability and provides alarm signals for AC OK and battery low via relay. It also includes a battery cut-off at 20V ±1V to protect the battery from deep discharge.

What input range does the Mean Well DRC-180B support?

The DRC-180B accepts a universal input range of 90 to 264VAC and also supports 127 to 370VDC input. That wide range makes it suitable for industrial and commercial environments where input conditions may vary across regions or systems.

Is the DRC-180B suitable for demanding industrial environments?

It is designed for demanding conditions, with an operating temperature range of -20°C to +70°C (derating per the derating curve). The unit also supports operation at altitudes up to 5000 meters and includes protection for overload, over-voltage, and over-temperature events.

How does the DRC-180B compare with a standard DIN rail power supply?

The main difference is that the DRC-180B combines a DIN rail power supply with UPS-related battery backup features in one unit. It also adds relay alarm signaling for AC status and battery-low status, which can be important in security and critical-power applications.

What certifications and compliance standards does the DRC-180B meet?

This model is approved to UL62368-1, Dekra BS EN/EN62368-1, EAC TP TC 004, and AS/NZS 62368.1 safety standards. Its EMC compliance includes EN55032 Class B and EN61000 series standards listed in the product data.
