In order to achieve maximum safety and system protection, always use an input line fuse. We recommended a 4 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 1.5KE180A. Output Voltage Adjustment The T rim input permits the user to adjust the output voltage up or down by 10%. This is accomplished by connecting an external resistor between the T rim pin and either the +Sense pin or the -Sense pin. To Trim Up Connecting an external resistor (Rd) between the T rim 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 Up Rd Trim Down Ru Fuse To Trim Down Connecting an external resistor (Ru) between the +Vout pin and the +Sense pin increases 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%.
