LVT-PSU | CAN-controllable Power Supply

The LVT-PSU allows you to extend the capabilities of a system through the control of available test power via automated means.

The system can be controlled via CAN, a Windows-based GUI with COM interfacing capability, an analogue input or its intuitive front panel.

15V, 20V, 30V and 60V nominal voltage ranges are available up to 3kW output. It can also be used in conjunction with our LVTGO-VBS range to broaden the range of robustness testing possible.

It therefore provides a compact convenient lab power source, with the capability to enhance existing test procedures.

Technical overview:

LVT-PSU front croppedThe LVT-PSU is a powerful desktop power supply unit for providing power to systems requiring a compact, rugged, controllable power source, with the ability to be controlled or monitored via CAN.

Primarily designed for automotive testing and development applications, this unit supports control from the front panel or remote control via CAN. This makes it suitable for unattended test applications such as hardware-in-the-loop, test automation and real-time control systems.

The LVT-PSU GUI interface comprises part of the main LVTest GUI application but is also available as a standalone application for those not using the LVTGO series.

From the interface, takes that can be achieved include:

LVT PSU Control Form GUI• Voltage control

• Current limit control

• Voltage readback monitoring

• Main output control

• Control state monitoring

• Mode control

The interface has been created using our real-time systems interface creation software, VISUALCONNX.

Main output terminals 2Minimise losses

Robust terminals with safety covers are employed, suitable for heavy-duty, high current cables

Selectable remote sense connections are also available, if required

HIL testing

The LVT-PSU is suitable for any HIL application that requires a remotely controlled power supply. Simply provide appropriate CAN messaging or analogue signals to the system to achieve the required power setting.

ECM robustness testing

The unit has been designed to complement our LVTGO-VBS vehicle battery simulator range. When the two systems are used together, this can significantly improve the range of tests that can be performed without the likelihood of a power protection trip. It can also reduce the wasted power dramatically.

The output stage can be current limited and also current limits if excessive power is dissipated, or if an excessive temperature occurs internally. This helps protect not only the unit, but the user and the device under test from damage due to incorrect connection or abuse.
