1.3 Standard Features
The CZE series incorporates several standard features
designed to optimize user operation.
Slow Start:
Provides a gradual increase in high voltage
output until the maximum set point is reached. Various
slow start times can be accommodated. Consult the
Spellman’s Sales Department for information on slow
start options. (The slow start time will be a function of
set point, input voltage and load conditions).
Polarity Control:
A TTL compatible input controls the
polarity of the high voltage output. A logic level HIGH
will give a Positive, a LOW a Negative. If left open, the
unit will default to Positive.
G.F.I.:
The Ground Fault Interrupt will give an
indication if there is more than approximately a 10%
difference between the return current test point and the
delivered current test point.
Polarity Indicator:
Two outputs indicate whether
positive or negative polarity has been selected.
Mode Indicators:
The two mode outputs indicate which
control loop is in control, the voltage or the current
regulation circuits.
1.3.1 Remote Operating Features
Remote Programming:
Allows remote adjustment of
the output voltage and current via an external voltage
source.
Remote Monitor:
Allows remote monitoring of the
output voltage and current.
High Voltage Enable/Disable:
Allows remote ON/OFF
control of the high voltage.
+10VDC Reference:
A +10VDC reference is provided
for remote programming via a potentiometer or resistive
divider.
1.4 Options
The options available are listed in Table 1.1. See section
5 for more information on the options along with
operating and set-up instructions. With few exceptions,
these options can be retrofitted to your power supply at
the factory in a short time. For price and retrofit
arrangements, contact the Spellman Sales Department.
