Description

The 0521002 is a state of the art, universal, digital control board. It has been designed to address numerous SCR/IGBT based power system challenges, allowing fast and economical product development and support. There is no longer a need to stock dozens of control board variants to meet your various product needs.

With the 0521002, nearly every system parameter is software adjustable, providing you a single control board solution for all your needs. Configuration and operating parameters are easily modified using the AAVPL GUI Configuration & Control Tool. The GUI also makes field updates fast and easy.

Systems operating from line voltages as high as 1000VAC are supported using the external HVI circuitry.
