Main Features and Functions 4.1 Operating Temperature Range The highly efficient design of Cincon's CBM100S series power module has resulted in their ability to operate within ambient temperature environments from -200C to 850C. The derating curve was drawn from the CBM100S power module. 6. Applications 6.1 CBM100S Series Derating Curve The operating temperature range of CBM100S series is -250C to +850C. When operating the CBM100S series, proper derating is needed. The maximum ambient temperature under any operating condition should not exceed 850C. The following chart is the derating curve of CBM100S series. 4.2 Output Protection Over current protection (OCP) CBM100S Series provide fully continuous short-circuit protection. The unit will auto recover until the short circuit is removed. To provide a protection in a fault condition, the unit is equipped with internal OCP. The unit will operate normally until the fault condition is removed. The power module will go to hiccup mode if output current reaches the condition of OCP, 130% to 200% rated current. Over voltage protection (OVP) All different voltage models have a fully continuous OVP. The power module will supply OVP, and the maximum voltage of OVP is 140% rated voltage. In the event of happen the OVP, the converter will shut down, and then It must recycle AC input to restart the converter. 5.
