The TCP3500 series is an AC-DC converter with adjustable DC output and universal 3-phase AC input. Conduction cooling (No Fans) 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 (50.4 kw). Passive or active current share system can be selected. 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. World-Wide 3-phase Input Voltage Range (nom. 115-277 V / 200-480 V) Power Factor > 0.94 High Power Density 16 W/in 3 94 Typical Efficiency Parallel Operation up to 16 Units (50.4 kw) Cold-Plate Cooling System -25 to 50 C of Cold-Plate Surface, -25 to 70 C of Ambient Air Temperature Possibility to Install 4 Units in 2U 19 Rack Advanced Performance for Fast Dynamic and Pulsed Load up to 100 khz (Optional) RS485 Interfaces Wide Output Voltage Range Fast Output Voltage Set Response (5 ms) Active Current Sharing
