                                    configuration. JQE Power Supplies feature full range voltage
control and current limit adjustment by means of multi-turn
front pane! controls. JQE power supplies have linear,
full-dissipation series-regulators (NPN) driven by an
integrated circuit operational amplifier. A sharp
current-iimit circuit renders the power supply completely
short-circuit proof. JQE power supplies may be readily
converted to provide constant the addition of an
external sensing resistor and a "current control". The
output of the JQE power supply is completely programmable.
All necessary connections are available on terminals at the
rear barrier-strip.
1*5 The compact design of the Kepco JQE "HALF-RACK" Series
was made possible by a unique heatsink design of exceptional
efficiency in combination with highly reliable iow-noise
fans. JQE power supplies feature all-silicon design with
conservatively rated components for added reliability.
1-6 JQE power supplies are identical in their mechanical
dimensions (Refer to FIG. 1-3) and in their electrical
specifications, except as noted inTABLE 1-1.
1-7 OPTIONS, Optional features of Kepco Power Supplies are
indicated by a letter following the model designation:
a) JQE Power Supplies with suffix "E" are equipped with an
"Ej0 Null" adjustment, which allows exact zero calibration
for precision programming applications.
b) JQE Power Supplies with suffix "HS" are optimized for
high speed programming. For these models, a special addendum
containing all supplementary specifications is provided in
the appendix of the manual. The "E;0 Nuil"{"E''} option is
automatically included with the "HS" option.
c) JQE Power Supplies with suffix "M" are equipped with two
dual range pane! meters which permit simultaneous monitoring
of the output voltage and output current. Meter
range-switches allow for full scale reading of either 10% or
100% of the voltage and current outputs.
d) JQE Power Supplies with suffix "T" have special
references which improve the temperature coefficient of the
supply (see paragraph 1-11 for specifications).
e) JQE Power Supplies with suffix "VP" are equipped with an
overvoltage protector. This electrical "crowbar" shorts the
output through a silicon controlled rectifier(SCR) if the
output voltage exceeds a preadjustable limit on the
protector {see paragraph 1-12 for specifications).
