The TCP3500/4000 Series is a universal 3-phase AC-DC converter with adjustable DC output and universal 3-phase AC input. Conduction cooling (no fan) makes this power supply series suitable for a wide variety of Industrial Applications that can utilize conduction or liquid cooling, negating the use of fans. Emphasis is given on reliability and long life. Parallel operation is possible up to 16 units (57.6 kW). Active current share system. The PSU includes DSP which enables monitoring of electrical parameters (including input voltage of all 3 phases) and controlling the PSU from system controller. An RS485 bus is used for command, monitoring and diagnostic information that can be supplied to a system controller.
