In order to achieve maximum safety and system protection, always use an input line fuse. We recommended a 10 A time delay fuse. It is recommended that the circuit has a transient voltage suppressor diode (TVS) across the input terminals to protect the unit against surge or spike voltages and input reverse voltage (as shown). A suitable part would be 1.5 KE180 A Littlefuse. Output Voltage Adjustment The Trim input permits the user to adjust the output voltage up by 10% or down by 10%. This is accomplished by connecting an external resistor between the Trim pin and either the +Sense pin or the -Sense pin. To Trim Down Connecting an external resistor (Rd) between the Trim pin and the +Sense pin decreases the output voltage. The following table can be used to determine the required external resistor value to obtain a percentage output voltage change of Δ%. -Vin +Vin1 +Vout +Sense Trim -Sense -Vout Vin TVS Load Trim down Rd Trim up Ru Fuse To Trim Up Connecting an external resistor (Ru) between the Trim pin and the -Sense pin increases the output voltage.

w w w .xppow er.com D C -D C C onverter Thermal Resistance Information Example (Without Heatsink) To determine the minimum airflow necessary for a RDH30072WS24 operating at an input voltage of 72 V, an output current of 12.5 A, and a maximum ambient temperature of 20°C: Determine Power dissipation (Pd): Pd = Pi-Po = Po(1- η)/η, Where Pi = Input power, Po = Output Power and η = Efficiency Determine airflow from airflow derating graph using data points for Pd=35.57 W and Ta = 20 °C Minimum airflow= 800 ft./min. To check that the maximum case temp of 100 °C is not exceeded: Maximum temperature rise is ΔT = Pd × Rca=35.57×2.19=77.9°C. Maximum case temperature is Tc=Ta+ ΔT=97.9°C <100°C. Where: Rca is the thermal resistance from case to ambient environment. Ta is ambient temperature and Tc is case temperature.
