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 traces. Additionally, a heat sink or thermal pad can be used to further improve thermal management.
To ensure reliable operation in high-vibration environments, Altech recommends securing the HE1HWPR/02 with screws or adhesive, and using a conformal coating to protect the device from moisture and contaminants. Additionally, the PCB should be designed with vibration-resistant components and a robust mechanical design.
Altech recommends using a combination of common-mode chokes, X-capacitors, and Y-capacitors to filter the input and output of the HE1HWPR/02. The specific component values and configurations will depend on the application and regulatory requirements.
Altech recommends using a combination of visual inspection, voltage and current measurements, and oscilloscope analysis to troubleshoot and diagnose faults in the HE1HWPR/02. The device also has built-in protection features such as overcurrent and overvoltage protection, which can be used to identify and isolate faults.
Altech provides a calculated MTBF of 1.5 million hours for the HE1HWPR/02, based on MIL-HDBK-217F calculations. The device is also designed to meet the requirements of IEC 62368-1 and UL 62368-1 for safety and reliability.
