GENERAL INFORMATION:
The “AUX” Series accessory provides a second fixed HV output in addition
to the adjustable main high-voltage powersupply output. This second output is
set for a specific fixed voltage at the factory. The “AUX” output
is achieved by adding a daughter board inside either 1/16A to 6A or 1/16C to
6C high-voltage power supplies.
This “AUX” board
is encapsulated with the main high voltage
power supply. All of the advantages of
the base power supply remain. Typical applications
are: Bi-Polar outputs, ionization/strike,
trigger coils, pulse generator or amplifiers,
tube elements such as G1, G2, cathode,
etc.
HIGH VOLTAGE "AUX" OUTPUT:
The “AUX” output is a non-isolated, unipolar output. Positive or
negative output must be specified. The polarity of this “AUX” is
not dependent on the polarity of the base HVPS.
Full capability is
available over an input range of 12 to
15VDC ±10% for 4W units and 24 to 28VDC ±5%
for 20W/30W units. The “AUX” fixed output is fully functional when
the main output voltage is adjusted from 100% to 75%. As the main output is adjusted
from 75% to 50% the “AUX” output current is reduced from 100% to
0%. The manufactured tolerance on the fixed output is ±5%. Line regulation
error is < 0.1%; load regulation error is < 0.1% per 100uA. The output
has a temperature co-efficient of ±0.11% per °C. Fixed outputs available
are:
| 47V @ 2mA |
450V @ 1mA |
| 94V @ 2mA |
600V @ 1mA |
| 141V @ 2mA |
750V @ 1mA |
| 188V @ 2mA |
900V @ 1mA |
| 235V @ 2mA |
1050V @ 1mA |
| 282V @ 2mA |
|
| 329V @ 2mA |
|
Note: Specified “AUX” output
should be <40% of the main output.
The “AUX” HV
output connection is via an additional
pair of standard .025in square IDC pins.
These pins can be used for PCB mounting
or direct wiring.

COMPATIBILITY:
The “AUX” Series matches the
standard “A” and “C” Series for
design methodology, remote control, enable/disable,
reference, shock, and vibration. Designed
and built utilizing a state-of-the-art
power conversion topology, these units
feature surface-mount technology and encapsulation
techniques, providing high reliability
and low cost. Base-power-supply output
current rating remains at full value. Nominal
input voltage should be used for maximum
efficiency.
SHIELDING:
All models are available with optional, six-sided, wraparound Mu-Metal Shielding.
This shielding attenuates magnetic and electrostatic emissions, while shielding
ripple reduction circuitry from outside noise. The high-voltage power supply
dimensions change by only 0.010in.
PACKAGING:
The auxiliary board is designed to be added to the “A” or “C” Series
high voltage power supply modules. The combined plastic package is UltraVolt's
4.9in³ PCB-mountable box with a footprint of only 5.5in². As always, optional,
six-sided Mu-Metal shielding, mounting brackets, mounting plates, and RF-tight,
chassis-mount ruggedized enclosures are available.
ENVIRONMENTAL:
The “AUX” Series meets the same
environmental specifications for temperature,
shock, and vibration as the “A” and “C” Series.
All units receive a 24-hour burn-in prior
to final test. Extended temperature range
is available along with other enhanced capabilities.
