The manual for the HP-6456B DC power supply provides detailed instructions on setup, operation, and troubleshooting, including how to connect input power, use remote programming, and operate in various modes such as series, parallel, and auto-tracking. It also covers the protection features against overloads and line dropouts, the use of cooling fans, and the function of the front panel controls and meters for monitoring and adjusting output voltage and current.
Manual Overview
The HP-6456B DC Power Supply is a transistorized, well-regulated unit designed for constant voltage and constant current operations. It features a single control knob for adjusting output voltage or current, and includes overload protection through automatic crossover operation. Troubleshooting involves checking the three-phase circuit breaker, which also functions as the on-off switch and secondary protection. Error sensing can be performed remotely via the programming strip at the rear. Calibration adjustments are facilitated by internal potentiometers for the front panel voltmeter and ammeter. For board-level guidance, the unit’s output terminals are isolated from the chassis, allowing either terminal to be grounded. The power supply supports parallel and series operations for increased output capabilities and can be remotely programmed for voltage or current adjustments. Cooling is managed by internal fans, ensuring proper airflow across heat-producing components. The unit is protected against input AC line phase dropout, which automatically isolates the output power bus until normal conditions resume.
Quick Issues Covered
- Diagnoses overloads via constant voltage/current automatic crossover protection.
- Error code analysis for AC line phase dropout protection.
- Circuit schematics assist in tracing internal power mesh failures.
