Question 1

I need an ac to dc converter with the following specifications: input voltage = 410v three phase ac voltage and output = 54.6vdc at 2000a.

Accepted Answer

Hello,

Sorry - we do not carry any power supplies compatible with 410V input, or with an output of 2000A.

Question 2

Does this supply limit output current to its max rating, or will it go into "hiccup mode" if the load tries to pull too much?

Accepted Answer

Hi,  The LRS outputs constant voltage, so the current is not controlled.  The wattage output is selectable, and it can only output the wattage selected for the model.  If the load is pulling to many watts for the model selected it would go into fault mode.

Question 3

Do you have any 48vdc x ~300w switch mode p/s suitable for use with servo/stepper drive.  regenerative feedback tolerant.  120-240vac input?

Accepted Answer

The smps has the efficiency, so 350w* efficiency is the actual power, for servo or stepper drive, you just need to make sure the voltage is OK, usually we use DIN rail power supply for servo or stepper drive, as these motors will be used on equipment. MEAN WELL don't have 300W smps, you could choose SP-320-48, about regeneration power, please use big resistor to solve, usually servo drive has this function itself.

Question 4

Is it possible to connect multiple of these power supplies in parallel to increment the output Amps?

Accepted Answer

Hello,

The Mean Well LRS series is not designed to have multiple power supplies connected in-parallel.  If higher wattage is needed we would suggest the HLG series which is available up to 600-Watt.
