The MEAN WELL DRC-100B is a 96.6-watt AC/DC DIN rail power supply with an integrated battery charger, designed for security and access control applications that require uninterruptible backup power. It provides a primary output (CH1) of 27.6V at 2.25A for the load and a dedicated charger output (CH2) of 27.6V at 1.25A for battery maintenance, enabling a DC UPS configuration in a single compact unit. The fan-less design uses free air convection cooling, and the universal AC input range of 90 to 264 VAC supports compatibility with a wide range of AC mains voltages. Agency approvals listed by Jameco include UL, CUL, TUV, CB, CE, and EN.
Key Features and Benefits
Dual-output UPS architecture - CH1 (27.6V @ 2.25A) powers the load while CH2 (27.6V @ 1.25A) simultaneously charges a backup battery, supporting uninterrupted operation in security and access systems.
Universal AC input range (90 to 264 VAC, 47 to 63 Hz) - Supports compatibility with a wide range of worldwide AC mains voltages without manual switching.
Fan-less free air convection cooling - Eliminates moving parts, which helps support quieter operation and reduced mechanical maintenance needs.
Built-in protections: short circuit, overload, and over voltage - Helps safeguard connected equipment and the battery within the manufacturer's stated protection limits.
Battery low protection and battery reverse polarity protection by fuse - Helps protect the connected battery from deep discharge and incorrect wiring.
Alarm relay outputs for AC OK and battery low status - Enables integration with monitoring systems to signal AC power loss or low battery conditions.
DIN rail mounting compatible with TS-35/7.5 and TS-35/15 - Supports straightforward installation into standard DIN rail enclosures and control panels.
LED power-on indicator - Provides a quick visual confirmation that the unit is energized.
100% full load burn-in test at the factory - Each unit is tested at full load before shipment, supporting confidence in out-of-box reliability.
3-year manufacturer warranty - Provides extended coverage for long-term installations.

Customer Questions
What battery type and capacity is compatible with the DRC-100B?
The DRC-100B charger output (CH2) is rated at 27.6V and 1.25A. Consult the MEAN WELL datasheet and your battery manufacturer's specifications to confirm that the battery chemistry, voltage, and capacity are compatible with this charge profile before connecting.
Can the DRC-100B be used with both 120V and 240V AC mains?
Yes. The universal input range of 90 to 264 VAC at 47 to 63 Hz supports both 120V and 240V AC mains without manual adjustment.
Does the DRC-100B require a fan or forced-air cooling?
No. The DRC-100B uses fan-less free air convection cooling. No external fan or forced airflow is required, though adequate clearance around the unit should be maintained per the datasheet installation guidance.
What DIN rail sizes does the DRC-100B support?
The DRC-100B can be mounted on standard DIN rail TS-35/7.5 or TS-35/15.
How does the alarm relay function work?
The DRC-100B includes a relay-based alarm signal that indicates AC power OK status and battery low status. This output can be wired to a monitoring or control system to alert operators of AC loss or a low battery condition.
Customer Concerns
Will the load and battery charger outputs operate simultaneously?
Yes. The DRC-100B is designed with two independent outputs: CH1 (27.6V @ 2.25A) supplies the load and CH2 (27.6V @ 1.25A) charges the battery at the same time, supporting a DC UPS configuration. Verify that your total load and battery charge current requirements fall within the rated output limits stated in the datasheet.
Is the output voltage adjustable to match my system's requirements?
The DRC-100B is rated at a fixed 27.6V output on both channels. Confirm that your load and battery system are designed for a 27.6V supply before installation. Refer to the MEAN WELL datasheet for any trim range details.
What happens if the AC input is lost?
The DRC-100B includes an alarm relay that signals AC loss. When AC input is interrupted, the connected battery (via CH2) can supply backup power to the load, depending on battery capacity and load current. The unit does not automatically switch load current to the battery internally - verify the system wiring configuration against the datasheet for your specific UPS application.
