To order negative logic ON/OFF control add the suffix “R” (Ex. MDW48S5-4000R) Heat Sink is optional, consult factor for ordering details. The MDW Series can meet EN55022 Class A with an external capacitor in parallel with the input pins. Recommended: 24Vin: NA 48Vin: 1µF/100V An external filter capacitor is required if the module has to meet EN61000-4-5. The filter capacitor Wall Industries suggest: Nippon chemi-con KY series, 220µF/100V, ESR 48mΩ.

Figure 3 gives several examples of acceptable configurations. The remote ON/OFF pin is an open collector/drain logic input signal (Von/off) that has -Vin as the reference voltage. If not using the remote on/off feature, open the circuit between the on/off pin and the -input pin to turn the module on. REMOTE ON/OFF IMPLEMENTATION Isolated-Closure Remote ON/OFF Level Control Using TTL Output Level Control Using Line Voltage OUTPUT VOLTAGE ADJUSTMENT Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of a module. This is accomplished by connecting an external resistor between the TRIM pin and either the +Vout or -Vout pins. With an external resistor between the TRIM and -Vout pin, the output voltage set point increases. With an external resistor between the TRIM and +Vout pin, the output voltage set point decreases.
