Kepco Series JQE Power Supplies are general purpose, precision regulated voltage sources in the "half rack" configuration. JQE Power Supplies feature full range voltage control and current limit adjustment by means of multi-turn front panel controls. JQE power supplies have linear, full-dissipation series-regulators (NPN) driven by an integrated circuit operational amplifier. A sharp current-limit 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 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 heat sink 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 reliability.
