Trim
The QHL150 series converters have no internal fuse. For
safety and system protection, always use an input line
fuse. A 2.0A time delay fuse is recommended. It is also
recommended the circuit has a transient voltage

Suggested Basic Layout
Output Voltage Sensing
The module will automatically trim the output voltage via the sense pins to the default values either locally or at the load. If not required, the
sense pins should be connected locally as indicated in the example EMC circuit.
Output Voltage Adjustment
The Trim input permits the user to adjust the output voltage up by 10% or down by 20%. This is accomplished by connecting an external resistor
between the Trim pin and -sense to trim up, or between the trim pin and +sense to trim down.

Example (Without Heatsink)
To determine the minimum airflow necessary for a QHL150300S12 operating at an input voltage of 300V, an output current of 12.5A, and a maximum
ambient temperature of 40°C:
Determine Power dissipation (Pd):
Pd = Pi-Po = Po(1-η)/η,
Pd = 12V × 12.5A × (1-0.89) / 0.89 = 18.54
Where Pi = Input power, Po = Output Power and η = Efficiency
Determine airflow from airflow derating graph using data points for Pd = 18.54W and Ta = 40°C
Minimum airflow = 400ft./min.
To check that the maximum case temp of 100°C is not exceeded:
Maximum temperature rise is
ΔT = Pd × Rca= 18.54 x 3.40 = 63.4°C.
Maximum case temperature is
Tc = Ta + Δ T = 40 + 63 = 103°C <100°C.
Where: Rca is the thermal resistance from case to ambient environment. Ta is ambient temperature and Tc is case temperature.
