Kepco JQE 55-20 Power supply
Model: JQE 55-20
Date: 1970
Category: Measurement instruments
Group: Power supply
                                    Kepco Series JQE Power Supplies are general purpose,
precision regulated voltage sources in the "FULL-RACK"
configuration. JQE Power Supplies feature full range voltage
control and current limit adjustment by means of multi-turn
front pane! controls. Dual range meters monitor output
voltage and load current JQE Power Supplies have linear,
full-dissipation series-regulators (NPN) driven by an
integrated circuit operational amplifier. A sharp
current-!innit circuit renders the power supply completely
short-circuit proof. JQE Power Supplies may be readily
converted to provide constant current by the addition of an
externa! 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 "FULL-RACK" Series
was made possible by a unique heatsink design of exceptional
efficiency in combination with highly reliable low-noise
fans. JQE Power Supplies feature all-silicon design with
conservatively rated components for added reliablity.
1-6 JQE Power Supplies are identical in their mechanical
dimensions (Refer to FIG. 1-3, "Mechanical Outline Drawing")
and in their electrical specifications, except as noted in
TABLE 1-1.
Ί_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
"E0 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 "Ej0 Null" ("E") option is
automatically included with the "HS" option.
c) JQE Power Supplies with suffix "M" are equipped with two
dual range panel 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 pre adjustable limit on the
protector (See paragraph 1-12 for specifications).
