Kepco JQE6

The Kepco JQE6 is a precision regulated DC power supply engineered for applications demanding stable, low-noise output and fine control resolution. This half-rack configuration unit delivers programmable constant voltage and constant current operation with full-range front panel adjustment and optional remote control via resistance or control voltage input. The linear series-regulator topology, driven by integrated circuit operational amplifiers, yields output ripple below 3 mV and MIL-STD-461 compliance.

## Technical Specifications

**Output Characteristics**
• Programmable constant voltage and constant current operation
• Output ripple: <3 mV
• Isolation: 500 V DC or p-p maximum between chassis and output terminals
• Common mode current: <5 µA RMS or 50 µA peak-to-peak at 115 V AC, 60 Hz
• Multiple output configurations available: 0–6 V at 45 A, 0–15 V at 12–25 A, 0–25 V at 10–20 A

**Input Specifications**

• Digital meter option (suffix "DM"): voltage accuracy 0.02%, current accuracy 1.5%
• Optional locking screwdriver-adjustable controls (suffix "L") prevent inadvertent drift
• Constant current operation via external sensing resistor

## Typical Applications

Laboratory test and measurement, precision instrumentation calibration, component characterization, and systems requiring MIL-STD-461 EMC compliance.

## Compatibility & Integration

Front panel controls and rear terminal configurations support standalone operation and integration into larger test systems via optional remote programming interfaces.
