Altech recommends a 4-layer PCB with a dedicated ground plane and thermal vias to dissipate heat. A minimum of 2 oz copper thickness is recommended for the power planes. Additionally, a thermal pad on the bottom of the device should be connected to a heat sink or a thermal management system.
To ensure reliable operation in high-vibration environments, Altech recommends securing the device using a screw-down or adhesive mounting method. Additionally, the PCB should be designed with vibration-resistant components and a rigid PCB structure to minimize flexure.
The 3D32UL is rated for a maximum surge current of 100 A for 10 ms, making it suitable for applications with high inrush currents.
Yes, the 3D32UL can be used in parallel to increase the overall current rating. However, it is essential to ensure that the devices are properly synchronized and matched to prevent current imbalance and reduce the risk of overheating.
Altech recommends using a fuse with a rating of 10 A to 15 A, depending on the specific application and operating conditions. The fuse should be selected based on the device's maximum current rating and the system's fault current requirements.
