Mean Well enters Digital Power Supply Arena with 3.2kW 1U Parallelable AC-DCs

April 19, 2018 by Paul Shepard

DRP/DPU-3200 series from Mean Well are 3.2kW single output rack-type/enclosed type ac-dc power supplies in 1U low profile with power density up to 37W/inch3. These series operate at 90- to 264-Vac input voltage and offer models with the dc output mostly demanded by the industry.

Each model is cooled by thermostatically controlled fan. Moreover, DRP/DPU-3200 series provide vast design flexibility by equipping various built-in functions such as output programming, active current sharing, remote ON-OFF control, auxiliary power, built in ORing FETs and Positronic connector to support hot swap (DRP-3200) and so on.

The DRP/DPU-3200 are the first fully digitalized PSU series from Mean Well. Digitalized PSU design further improves switching efficiency, power density, reliability and also makes possible programmable tuning on electrical parameters and internal control and human machine interface (HMI).

System-wise power management is feasible by using digital controller and PMBus or CANBus communication protocols to realize synchronous monitoring on input and output parameters. Step by step, the goal of intelligent power supply is therefore achieved in the long run.

Both series are suitable for applications in industrial automation, Telecommunication equipment, battery charging equipment and EV charging stations that require power source capable of high output (10kW and beyond).
