Bel Power Solutions recommends a 4-layer PCB with a solid ground plane, and thermal vias under the module to ensure efficient heat dissipation. A minimum of 1-inch clearance around the module is also recommended for airflow.
To ensure reliable start-up and shutdown, Bel Power Solutions recommends a soft-start circuit to limit inrush current, and a controlled shutdown sequence to prevent voltage spikes. Additionally, a minimum input voltage of 9V is recommended for reliable start-up.
Bel Power Solutions provides derating curves for temperature and altitude in their application notes. For example, the module's output power is derated by 2.5% per 1000 feet above sea level, and by 1% per 10°C above 40°C ambient temperature.
Yes, the BP1601-9RG can be used in a redundant or N+1 configuration. Bel Power Solutions recommends using a diode ORing circuit to connect multiple modules in parallel, and a load-sharing circuit to ensure equal current distribution.
Bel Power Solutions recommends using a CISPR 22 Class B EMI filter at the input of the BP1601-9RG to ensure compliance with electromagnetic interference regulations. The filter should be designed to attenuate conducted emissions in the frequency range of 150 kHz to 30 MHz.
