Thermal Protections and Precautions
Both channels of the NI PXI-4130 are protected against excessive temperatures and shut down in the presence of excessive heat.
During normal sourcing operation on channel 1 (up to 40 W output), the thermal protection should not engage over the rated ambient temperature range of the device. Also, sinking power levels within the rated specifications of the device should not trigger the thermal protection when the device is within the ambient temperature range.

Hot Surface Do not touch the outer shield of the NI PXI-4130 as it may become very hot during an overtemperature condition. |
Thermal protection for channel 1 may also become engaged if the output becomes unstable because of inductive loads in the highest current range. If you are operating the NI PXI-4130 within the rated specifications and the thermal protection is engaging, refer to Source Stability Under Reactive Loads and Output Capacitance Selection to determine if instability may be a factor in overtemperature operation of your device.
