WARNING
AFTER TURNOFF, DO NOT HANDLE
THE LOAD UNTIL THE CAPACITANCE
HAS BEEN DISCHARGED!
LOAD CAPACITANCE MAY BE DISCHARGED BY
SHORTING TO GROUND.
WARNUNG
Nach drm Ausschalten des Gerätes die Last erst
berühren wenn diese vollständig entladen ist.
Die elektrische Kapazität der Last kann durch
einen Kurzschluß zur Erde entladen werden.
WARNING
THE VOLTAGE MONITOR ON THE POWER
SUPPLY FRONT PANEL DOES NOT READ THE
OUTPUT VOLTAGE WHEN THE POWER IS
TURNED OFF, EVEN IF A CHARGE STILL EXISTS
ON THE LOAD.
WARNUNG
Der Spannungsmonitor arbeitet nicht bei
abgeschalteter Versorgungspannung, auch nicht
wenn die Last noch aufgeladen ist.
CAUTION
ALWAYS OPERATE THE UNIT WITH THE COVER
ON. DO NOT ATTEMPT TO ACCESS OR REPAIR
ANY INTERNAL CIRCUITS. DANGEROUS AND
LETHAL VOLTAGES ARE GENERATED INSIDE
THE MODULE.
CAUTION
Betreiben Sie das Hochspannungsnetzteil
ausschließlich mit geschlossenem Gehäuse.
Versuchen Sie nicht die internen Schaltkreise zu
berühren oder zu reparieren, da
lebensgefährliche Hochspannungen in Innern
erzeugt werden.
3.2 Standard Features
A note on remote interface circuitry and remote signal
grounding: whenever possible, electrical isolation should
be provided when interfacing with any high voltage
power supply. For enable/disable signal connections, an
isolated relay or optocoupler should be used. If possible,
analog programming and monitoring signals should be
isolated via analog isolation amplifiers. Spellman
application engineers are available to assist in interface
circuitry design. All interface cables should be properly
shielded. All power supply signals should be referenced
to the power supplies signal ground or power supply
chassis ground
REMOTE PROGRAMMING: Allows remote
adjustment of the output voltage and current via an
external voltage source. A 0 to 10VDC signal is supplied
to Pin 6/8 of the control input connector for voltage
programming. A 0 to 10 VDC signal is supplied to Pin
7/9 of the control input connector for current
programming. Programming signals should be referenced
to Pin 9/11 of the control input connector signal ground.
By adjusting the voltage source from 0 volts (zero output)
to 10 volts (full rated output) the desired output can be
selected. See Figure 3.3A for wiring diagram and
specifications.
An alternate method of controlling the output remotely is
by using external resistance such as a potentiometer or a
resistor network. See Figure 3.3B for wiring diagram.
Remote Monitoring: Test points are made available for
monitoring the voltage and current output. The test points
are always positive regardless of the output polarity,
where zero (0) to 10 (10) volts equals 0-100% of the
output. See Figure 3.4 for test point wiring.
