A harsh environment generally refers to extreme temperatures, such as extremely hot or cold conditions, that can be challenging for humans to endure. In terms of power supply, a harsh environment can be defined as one where the power supply may be exposed to conditions such as heat, moisture, cosmic rays, and vibration. Thermal management is always a common challenge to the power supply in harsh environments.
Our newly released CBM150S series is an AC-DC brick type fanless power supply that is capable of providing rated power 150W within a full brick size and an ultra-slim profile only 19.7 mm. This series is equipped with the essential safety approvals for IEC/UL/EN 62368-1 3rd edition.
Our brand new CQB75W14 series, a 14:1 ultra-wide input DC-DC converter, delivers 75W of regulated output power in a standard quarter brick size of 2.28 x 1.45 inches (57.8 x 36.8 mm). This series has safety approvals for IEC/UL 62368-1 and 3000Vac isolation (input to output).
In general, for AC-DC power supplies and DC-DC converters, the recommended de-rating curves of output power are provided according to combination of various conditions such as operating voltage, temperature, or airflow. End-product designers could select power products based on this information. The de-rating operation is to ensure the safety the power system, heat dissipation performance, and reliability. Our clients are widely spread all over the world and the operating voltage, temperature, and environment of different markets differ. Therefore, it is essential to ensure the stability and reliability of power system. Violating the design rules and application conditions would have adverse effects on the life and reliability of power supply and end devices.
The CQB100W14 series is our new 14:1 ultra-wide input DC-DC converter that provides 100W of regulated power in the industrial standard quarter brick size of 2.28 x 1.45 inches (57.9 x 36.8 mm). It has safety approvals for IEC/UL 62368-1 and 3000Vac isolation (input to output).
