The TCP3500/4000 Series from Bel Power Solutions offers a universal 3-phase AC-DC conversion with adjustable DC output, designed for industrial applications. This series emphasizes reliability and long life, utilizing conduction cooling (no fan) which makes it suitable for systems that can employ conduction or liquid cooling.
Key electrical specifications include a wide 3-phase input voltage range from 180 to 528 VAC, a nominal output voltage of 28 VDC (adjustable from 10-32 VDC), and a maximum output current of 125 ADC, delivering up to 3500W of power. The converter boasts a high efficiency of 94% typical and a power factor greater than 0.94. It supports parallel operation for up to 16 units, enabling a total output of 57.6 kW.
Designed for demanding environments, the series operates within a cold-plate surface temperature range of 0 to 50°C and an ambient air temperature range of 0 to 70°C. It includes an RS485 bus for command, monitoring, and diagnostic information, controlled via DSP. The unit is SEMI F47 compliant and features active current sharing and a fast output voltage set response of 5 ms.
Mechanically, the converter has dimensions of 400 x 103 x 85 mm (15.74 x 4.05 x 3.34 inches) and is designed for rack mounting. Safety standards include 62368 with approvals such as CB, CE, and CSA.
