The new OPP-200 programmable Modbus power supply unit (PSU) from VXI Power is designed for use in test and instrumentation systems where accurate control and monitoring are important.

From its compact 3U housing, the PSU delivers an output power of 200W with voltage programmable from 2VDC to 20VDC in steps as small as 1mV.

Output current limit can be preset in 10mA steps up to 10A.

Equipped with an RS485 serial interface, the OPP-200 is programmed by a host computer using the industry-standard Modbus communications protocol.

Up to 192 of the units can be operated on the same bus and this modular approach allows users to configure a power system with different variants of the OPP-200 to meet the precise needs of their particular application.

A dedicated 3U 19in (48cm) subrack is available to enable multiple power supplies to be integrated into the host equipment.

Incorporating a backplane, power distribution and auto address select facilities, the subrack can accommodate up to six OPP-200 units.

The PSUs are hot swappable and individual status can be viewed locally via the backlit alphanumeric display on each unit’s front panel.

The parameters to be displayed are selected via the host computer.

Application support is available for customers wanting to use the power supply in a Labview environment.

The company can also provide other voltage and current configurations to suit specific requirements.
