Application Notes
Input Fusing and Safety Considerations
The QHL750 series converters have no internal fuse. In
order to achieve maximum safety and system
protection, always use an input line fuse. We
recommended a 30 A fast acting fuse. It is also
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 SMCJ78A.

Output Voltage Adjustment
The Trim input permits the user to adjust the output
voltage up by 10% or down by 40%. This is
accomplished by connecting an external resistor
between the Trim pin and either the Vout (+) pin or the
Vout(-) pin (COM pin).
To Trim Down
To Trim Up
Connecting an external resistor (Rd) between the Trim pin and the
-Sense pin decreases the output voltage. The following equations
determine the required external resistor value to obtain a percentage
output voltage change of Δ%.
Connecting an external resistor (Ru) between the +Vout pin and the
+Sense pin increases the output voltage. The following equations
determine the required external resistor value to obtain a
percentage output voltage change of Δ%.

Example (Without Heatsink)
To determine the minimum airflow necessary for a QHL750300S48 operating at an input voltage of 300 V, an output current of 11 A, and a maximum
ambient temperature of 25°C:
Determine Power dissipation (Pd):
Pd =48 V× 11 A×(1-0.91)/0.91 = 47.47
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=47.47 W and Ta = 25 °C
Minimum airflow= 800 ft./min.
To check that the maximum case temp of 85 °C is not exceeded:
Maximum temperature rise is
ΔT = Pd × Rca=47.47×1.23=58.38°C.
Maximum case temperature is
Tc=Ta+ΔT=83.38°C <85°C.
Where: Rca is the thermal resistance from case to ambient environment. Ta is ambient temperature and Tc is case temperature.
