Compatible Power Adapter

The WAWEIS AC adapter replaces the original power supply for the Drobo DDR3A21 4-bay direct-attached storage array. It delivers the required power for USB 3.0 operation so the enclosure runs without interruption. The unit is built for users who need a dependable mains charger for this specific DAS model.

Input Range and Protection

World wide input voltage covers 100-240VAC at 50/60Hz for global mains compatibility. Safety circuitry includes over current protection, total power protection, over voltage protection and short circuit protection. A smart chip adds overheating protection while isolation materials provide anti-interference performance.

Build Integration

A 10 ft power cord gives flexible placement between the wall outlet and the storage array. FCC, CE and RoHS certifications confirm regulatory compliance for office or home environments. The adapter frees the DAS from reliance on the original brick and supports continuous operation of the 4-bay enclosure.

Questions about this item

How do I install the WAWEIS AC adapter for my Drobo DDR3A21 4-Bay DAS, and which step is often missed?

Connect the barrel plug to the unit's power port, attach the detachable mains lead to the brick, then plug into a 100-240VAC 50/60Hz outlet; the step often missed is seating the mains lead fully into the adapter body.

What maintenance or replacement will this WAWEIS power supply need over time?

The 10 ft cord and IEC lead should be inspected periodically for wear or damage; the adapter itself has no user-serviceable parts and is replaced as a unit if protection circuits trip permanently.

What limit appears first on this WAWEIS adapter during sustained heavy loads on the Drobo DDR3A21?

Built-in over-current, over-voltage and short-circuit protections will shut the output down before the supply overheats, so the protection threshold is the first limit reached.
