Description
The MEAN WELL UDP-400R-4.2 provides 4.2VDC at up to 80A with 336W rated output and incorporates built-in redundancy for LED display systems requiring increased power continuity. Two UDP-400R units can be connected in parallel so that if one PSU becomes unavailable, the second supply can support the load automatically. The 26mm low-profile design is combined with 90-264VAC input, active PFC, adjustable 3.8-4.2V output, fanless cooling, conformal coating and comprehensive electrical protection. When operated in parallel, the maximum load must not exceed the rated power of a single PSU.
