Overview

DRC-100B is the CH1: 27.6V / CH2: 27.6V output model of this series: rated current CH1: 2.25A / CH2: 1.25A, rated power 96.6W, typical efficiency 89%.

DRC-100 is a 96W 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-100 accepts the universal input between 90VAC and 264VAC, and supplies 13.8VDC and 27.6VDC at output, respectively. With the efficiency up to 89%, it can operate with air convection cooling under -30℃ 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 signalling 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 cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.
5. 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 )
6. Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is recommended.
7. 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).
8. The battery voltage is lower than the CUTOFF voltage and cannot perform AC reset charging.

FAQ

Can I use the DRC-100B for a 27.6V industrial control load up to 2.25A?

Yes. The DRC-100B provides constant voltage output at 27.6V and is rated for 2.25A, with a total output of 96.6W. It is suited to 27.6V panel loads that stay within those ratings.

Is the DRC-100B a fit for 24V-class automation equipment that operates at 27.6V DC?

It is intended for equipment that specifically accepts 27.6V constant voltage input. The available output is 2.25A and 96.6W, so the connected load must remain within that range. This makes it relevant for control and automation devices designed around a 27.6V nominal bus.

Can the DRC-100B be used in DIN rail battery-backed control systems?

It is designed as a DIN rail power supply with UPS function, which makes it relevant for control systems where backup behavior is required. Electrically, the load must be compatible with 27.6V constant voltage and stay within 2.25A or 96.6W. That is the key fit check for embedded or industrial use.

Is the DRC-100B suitable for outdoor or washdown environments?

The unit has an operating temperature range of -30°C to +70°C, with load derating at higher temperatures per the derating curve, so temperature capability is broad. However, no IP rating is provided in the listed specs. Based on the provided data, outdoor exposed or washdown suitability is not established.

What are the main differences between the DRC-100B and the other DRC models?

The DRC-100B is rated at 96.6W and 27.6V, with 2.25A for the load (CH1) and 1.25A for battery charging (CH2), for 24V battery systems. Its sibling on the same datasheet, the DRC-100A, is also 96.6W but at 13.8V, with 4.5A for the load and 2.5A for charging, for 12V battery systems. Both share the 90-264VAC input, DIN rail mounting and AC OK / Battery Low relay alarms.
