Bel Power Adds Fan-Cooled TXP3500 Series to its High Power Portfolio

By Rob GrayMarch 22, 2017

Bel Power Solutions, a global supplier of premium power management devices, introduced the TXP3500 Series as an extension of their high power portfolio. The TXP3500 Series comes with a maximum 3500 W AC-DC power supply that is suitable for industrial machinery, process and control applications.

The high power series of AC-DC converters can be deployed in an array of industrial applications where efficiency is a crucial factor. The series integrates a PFC front-end stage along with an isolated DC-DC stage to convert the 3 Phase input voltage to a low DC output voltage.

Bel’s TXP3500 product line includes the industry-leading DSP technologies, which can monitor electrical parameters as well as enable control of the power supply unit from a system controller. The device also incorporates RS485 / CAN bus communication that can monitor, give diagnostic information, and create an interface between system controllers.
