Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 6643A #9264421 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 6643A is a multi-mode, precision, low-noise programmable DC power supply rated for 500 W of continuous output. With precise, fast and low-ripple voltage and current regulation, this power supply makes it an ideal choice for prototyping, testing and troubleshooting in a wide range of applications. HP 6643A features a two-quadrant output between 0-63 V and 0-6.3 A enabling enabling superior performance in both current sourcing and current sinking. It comes with advanced electronic protection systems including over-voltage, over-current, short-circuit, and overtemperature. It also comes with a temperature-compensated output and a precision voltage drift trim AGILENT 6643A has excellent line and load regulation, providing stability with low output impedance. The low-noise performance (10mVrms/0.2mArms) ensures an accurate voltage accuracy at the output and the state-of-the-art pulse width modulation enables both high efficiency (up to 95%) and low-ripple operation. 6643A comes with a comprehensive set of features, such as built-in voltage ramps, multiple output types (single output, multiple/parallel outputs, and load-sharing outputs) and voltage/current mode operation with 20 pre-programmed profiles. The power supply can be controlled and monitored via GPIB, LAN, or USB interface, or remotely with an Apple iPad. The built-in six-digit digital multimeter and the front-panel display allow the user to control and monitor voltage and current values, diagnostics, output configurations, and operating modes while the front and rear-panel LEDs provide an appropriate user interface and safety interlock. All in all, KEYSIGHT 6643A is a versatile, high-performance power supply that delivers superior performance and excellent regulation accuracy, in a robust and reliable package. It is a great choice for testing and troubleshooting a wide range of applications.
