Overview

The DUPS-28-MDC-300-A02 model is a DC uninterruptible power supply with fixed-voltage multiple outputs. Thanks to its integrated BB2590 battery, it activates when input voltage is lost or drops below threshold, ensuring uninterrupted power to connected loads. The input voltage range is 28–36V DC, and the device is configured to provide 28V, 16V, and 12V outputs.

It features constant current and constant voltage charging modes, as well as a built-in continuous self-test system. Heat dissipation is managed without a fan, delivering a silent and durable solution. Compliant with MIL-STD-810G, it is resistant to environmental challenges such as humidity, vibration, shock, sand, and salt. The system supports four different operation modes: power supply mode, portable power mode, uninterruptible power mode, and charge-only mode.

Uninterrupted Energy with Integrated Battery

In the event of a power interruption or voltage drop at the input source, the device seamlessly maintains its outputs via the integrated BB2590 battery, ensuring uninterrupted operation of critical loads. This guarantees reliable power delivery under field conditions.

Multiple Output Voltages

DUPS-US-28M-300-A02 offers three separate outputs: 28 VDC, 16 VDC, and 12 VDC, allowing simultaneous power delivery to multiple devices. In the event of a power loss, the unit continues to supply these voltages in a regulated manner. It also provides adjustable output within the 28–36 VDC range.

Smart Charging and Protections

The intelligent charging circuit operates in constant current and constant voltage modes, ensuring safe charging while preserving battery life. It includes built-in overvoltage and undervoltage protection. Additionally, a continuous self-test circuit monitors the device’s internal status in real time.

Compact, Quiet and Durable Design

The fanless cooling design ensures silent operation. With its compact dimensions of 111×180×180 mm, the device is easily portable. It has successfully passed MIL-STD-810G environmental durability tests, making it a reliable solution for demanding field conditions.
