4.13.3. How to Use the Charts
The power dissipation in the chart includes the losses of the rectifying bridge.
Regarding Figure 38 and Figure 39, the following should be noted:
DC Bus Voltage (VDC)
Rectified Voltage (VAC)
560
3X400
680
3X480
330
3X230
The charts above are based upon theoretical worst-case conditions. Actual test results show
30% to 50% better power dissipation.
To determine if your application needs a heat sink:
1.
Allow maximum heat sink temperature to be 80 °C or less (shunt down is 6 °C to 8 °C
higher).
2.
Determine the ambient operating temperature of the Gold Drum HV (High Voltage) as ≤
40°C.
3.
Calculate the allowable temperature increase according to the following example: For an
ambient temperature of 40 °C, ΔT = 80 to 40°C = 40°C
4.
Use the chart to find the actual dissipation power of the drive. Follow the voltage curve to
the desired output current and then find the dissipated power.
4.14. Initializing the System
After the Gold Drum HV (High Voltage) has been connected and mounted, the system must be
set up and initialized. This is accomplished using the Elmo Application Studio, Elmo’s Windows-
based software application. Install the application and then perform setup and initialization
according to the directions in the Elmo Application Studio User’s Manual.
