4.4.3 System temperature
Triton power stage integrates power MOSFET transistors. Switching them means charging and discharging
thethose capacitors, and this is done thousands of times per second which results in power losses and a
temperature increase even at 0 current. Therefore, a PCB temperature of 60 ºC or more might be measured,
even while no current is passing through the motor, specially of the drive is not ventilated at all.
Recommendation: when motor is off, exit motor enable mode, as this will switch off the power stage.
4.4.4 Improving heat dissipation with a heatsink
A heatsink is required to reach the nominal current at any ambient temperatures (except for TRI-1/48-x-
C). When using high efficiency heatsinks or in enclosed spaces the equation can be simplified as follows.
Current derating
The current derating graph is only indicative and is based on thermal tests performed in a climatic
chamber where there was enough room for natural air convection. Each application may reach
different ratings depending on the installation, ventilation and/or housing.
Current derating is only a recommendation and is not performed automatically by the drive.
