PDB series water cooling programmable DC power supply

Short Description:

PDB series programmable power supply is a high precision, high stability water cooled DC power supply, the maximum output power up to 40kW. IGBT inverter technology, efficient DPS as the control core, through the digital encoder voltage and current high-precision regulation, wide voltage design, to meet the use of a variety of different power grid.

Features

● Standard 3U chassis design
● IGBT inverter technology, high-speed DSP as the control core constant voltage/constant current free switch
● Telemetry function to compensate for load line pressure drop
● High precision voltage and current regulation via digital encoder. Built-in RS 485 and RS 232 standard interface
● External simulation programming, monitoring (Ov~5V or Ov~ 10V)
● Optional isolation type analog programming, monitoring (OV~5V or OV~10V)
● Support multi-machine parallel operation
● Light weight, small size, high power factor, energy saving
