TXP3500 series | Bel Power Solutions

Application

The TXP3500/4000 series of fan cooled power supplies convert the universal 3 phase AC line to an adjustable, wide range output at 3.5/4 kW and a 12 V standby output.

Thanks to active current share system up to 8 units may be operated in parallel (28/32 kW).

This industrial Power Supply Unit (PSU) includes DSP technology which enables monitoring of all electrical parameters and allowing control of the PSU from a system controller via RS485 / CAN bus communication interface. The output voltage is adjustable also by a resistor connected to Margin input.

The 2U package makes the unit suitable for using in workstations, storage systems, racks for industrial and many other applications.
