The PXB series of bidirectional high-capacity DC power supplies sales launch announcement


Apr 07 ,2023

Dear Valued Customer,

We are pleased to announce that we have launched sales of the PXB series of bidirectional large-capacity DC power supplies.

The PXB series of bidirectional DC power supplies combine power and regeneration in a single unit. The high-density mounting technology allowed for condensing a large output capacity of 20 kW into a 3 U-size housing. The power supply is available in three rated voltages of 500 V, 1000 V, and 1500 V. The input power can be either 3-phase 3-wire 200 V or 3-phase 3-wire 400 V. This series is also scalable and supports the one-control parallel operation of up to 10 units.

The first shipments are scheduled for late April.



Constant voltage 0 ~ 500V Constant current -120A ~+ 120A Constant power 20kW


Constant voltage 0 ~ 1000V Constant current -60A ~+ 60A Constant power 20kW


Constant voltage 0 ~ 1500V Constant current -30A ~+ 30A Constant power 20kW
