Ultravolt 60W User manual

GENERAL INFORMATION:
This High Power line of high-voltage regulated DC to DC
converters is an extension of the “C” Series, directly addressing
the high power density needs of >30 watt applications. High
Power “C” units provide up to 60/125/250 watts. This high
power density is especially suited to high-energy systems with
large capacitances, fast repetition rates, or high continuous-
DC-power requirements. See Application Note 10 for more
charging information.
COMPATIBILITY:
The High Power “C” Series matches the standard 30 watt
“C” Series for design methodology, wide input range, remote
control, enable/disable, and reference.
LOW VOLTAGE INPUT:
The input is a dual row, 7 pin IDC header. The first row has
the same pin out & signals as the 30 watt “C” Series. The
second row provides the pins required to support the High
Power “C” Series version. Connections can be made via
J-hooked and soldered leads, or via AMP MOD-U connectors
with high-pressure, high-current pins. See Application Note
3. A direct-mounted PCB with header sockets, such as the
UltraVolt interface board, can mate to the chassis-mounted
power supply’s input header. Seven #4-40 and two #2-56
PEM nuts are provided on the top cover for this purpose. The
250 watt models also feature a four-pin, high-current input
power connector.
HIGH VOLTAGE OUTPUT:
The High Power “C” Series is a non-isolated, unipolar
converter. Positive or negative output must be specified.
Output is adjustable from 0 to 125V, 250V, 500V, 1kV,
2kV, 4kV or 6kV on all 60W/125W/250W units. Additionally,
60W/125W models are adjustable from 0 to 8kV, 10kV, 12kV
or 15kV. As the output voltage is reduced towards 0, the
maximum current capability remains unchanged. Internal
capacitance is kept to a minimum to facilitate fast-rise
applications. Most fast-rise applications involve charging a
storage capacitor, which also acts as an additional output
filter/storage capacitor. If your application is continuous DC
bias power, an external filter/storage capacitor should be
added. Contact UltraVolt’s customer service department for
recommended capacitor values.
OUTPUT VOLTAGE MONITOR:
A 100 MegWdivider provides a 100:1 voltage monitor on
models up to 6kV. On models 8kV and higher a 1 GigW
divider provides a 1000:1 test point. The monitor has an
output impedance of 1.1 MegWand is calibrated for use
with a 10 MegWinput impedance meter. Overall accuracy is
+/-2.0% with a temperature coefficient of +/-200 ppm per °C.
For applications requiring a different scale factor, such as an
ADC compatible design, an external resistor may be added in
parallel with the output.
OUTPUT CURRENT MONITOR:
The High Power “C” Series is equipped with an output current
monitor. Current from the high-voltage multiplier can be
monitored by reading the voltage generated between Output
Monitor pin 3 and Signal Ground pin 5. The monitor has an
output impedance of 5.1 k W . Internal voltage dividers create a
small linear offset voltage.
MECHANICAL:
The High Power “C” Series converters are packaged in
chassis-mount aluminum enclosures, mounted using the
four #8-32 studs and thermal interfacing material. Electrical
connections are via wiring harness or top cover mounted
PCB. The 60W/125W units up to 6kV utilize the standard 19
in3enclosure. The 60W/125W units 8kV and higher use the
extended 38 in3enclosure along with the 250W units up to
6kV. See Application Note 6 for thermal considerations and
mounting configurations.
ENVIRONMENTAL:
The High Power “C” Series provides full power at case
temperature from -40 to +65°C. Extended temperature range
is available along with other enhanced capabilities. Please
contact the factory. All units receive a 24 hour burn in prior to
final testing.
