GENERAL INFORMATION:
The "AUX" Series accessory provides second and third adjustable positive
HV outputs in addition to the adjustable main positive high-voltage power supply
output. The “AUX” outputs are set for a specific voltage range at
the factory. One output is referred to as the Focus, one as the Grid. The “AUX” is
achieved by adding a daughter board inside the “10A→35A” high-voltage
power supply. This “AUX” board is encapsulated with the main high-voltage
power supply in a special taller enclosure to accommodate the height of the adjust
pots. Typical applications are: CRT Raster Display, X-Y CRT Display, E Beam Bias.
HIGH VOLTAGE "AUX" OUTPUTS:
The “AUX” outputs are non-isolated, positive, unipolar outputs. Full
capability is available over an input range of 12 to 15VDC ±10% for 4W
units and 24 to 28VDC ±5% for 15W/30W units. The Focus “AUX” output
voltage is fully functional when the main output is within the range specified
on the ordering information table. The manufactured tolerance on the output voltage
range provided is ±5%. Line regulation error is <0.1%. Load regulation
error is 0.5V per uA. The outputs have a temperature co-efficient of +0.11% per
oC. Each “AUX” output has a current capability of 0 to ±25uA,
contact factory for higher current. Each “AUX” output can be adjusted
using an internal single-turn potentiometer. The potentiometer adjusts from a
factory-set voltage down to 450VDC lower. Specific outputs available are:
| Standard TC: |
Compensated TC: |
| 300V |
500V ± 200PPM |
| 450V |
650V ± 408PPM |
| 600V |
800V ± 537PPM |
| 750V |
950V ± 626PPM |
| 900V |
1100V ± 690PPM |
| 1050V |
|
The “AUX” Grid
HV output is via pin 10 on an additional
pair of standard .025" square IDC pins.
These pins can be used for PCB mounting or
direct wiring. The “AUX” Focus
HV output is via an 18" long flying
lead.

COMPATIBILITY:
The “AUX” Series matches the
standard “10A → 35A” 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.
Output current monitor is rescaled to accommodate
the “AUX” current.
SHIELDING:
All models are available with optional six-sided, wraparound Mu-Metal Shielding.
This shielding attenuates magnetic and electrostatic emissions, while shielding
internal circuitry from outside noise. The high-voltage power supply dimensions
change by only 0.010".
PACKAGING:
Since the Auxiliary board is designed to
fit inside the “10A→35A” footprint,
the width and length remain unchanged.
To accommodate the adjust pots, all 4W
units are 1.175" ±0.050" high,
15W and 30W units are 1.235" ±.050" high.
Standard packaging is our plastic PCB-mountable
box. As always, optional six-sided Mu-Metal
shielding, chassis mounting brackets and
mounting plates are available.
ENVIRONMENTAL:
The “AUX” Series meets the same
environmental specifications for temperature,
shock, and vibration as the “10A → 35A” Series.
All units receive a 24-hour burn-in prior
to final test. Extended temperature range
is available along with other enhanced capabilities.
