R&S HM8143 Three Channel Arbitrary Power Supply

The R&S®HM8143 power supply is the perfect choice whenever two-quadrant operation is needed.

Besides the source functionality, it also provides electronic loads to accurately sink current and dissipate power in a controlled manner, for example to emulate the characteristics of a battery being charged or unloaded.

R&S HM8143 Key Features

  • 2 × 0 V to 30 V / 1 × 5 V, 3 × 2 A (max. 130 W)
  • Linear regulated, two-quadrant power supply (current source and sink)
  • Setting and readback resolution: 10 mV, 1 mA
  • External modulation of output voltages up to 20 kHz
  • RS-232/USB dual interface, IEEE-488 (GPIB) optionally

    The R&S HM8143 power supply is the perfect choice whenever two-quadrant operation is needed. Besides the source functionality, it also provides electronic loads to accurately sink current and dissipate power in a controlled manner, for example to emulate the characteristics of a battery being charged or unloaded.

    The R&S HM8143 offers two channels with up to 30V source and sink functionality plus one source channel with 5V.
    Electronic fuse and modulation inputs are additional features.

    R&S HM8143 Features:

    • 2 x 0V to 30V / 1 x 5V, 3 x 2A (130W)
    • Linear regulated, two-quadrant power supply (current source and sink)
    • Realtime voltage and current values
    • Advanced parallel and serial operation
    • Setting and readback resolution: 10mV, 1mA
    • Electronic fuse and tracking mode
    • Front connectors: 4mm safety sockets
    • SENSE connectors for line loss compensation (30V channels)
    • External modulation of output voltages up to 20kHz
    • Arbitrary module: 4,096 points, 12bit
    • RS-232/USB dual interface, IEEE-488 (GPIB) optionally

    Parallel and serial operating modes

    â–º In the parallel operating mode, channels can be bundled to achieve higher currents.
    ► In the serial operating mode, channels can be combined for higher output voltages.

    Modulation inputs

    â–º The R&S HM8143 provides two modulation inputs on the rear, so it can be used as a power amplifier with a frequency range from DC to 20 kHz. Applications include testing of AC motors, relays, etc.

    Electronic fuse

    â–º In order to provide even better protection than current limiting, the R&S HM8143 offers the feature of an electronic fuse. As soon as the current limit is reached, all outputs are simultaneously disabled.

    Arbitrary function

    â–º The arbitrary mode can be used to generate a time/voltage flow. A table comprising up to 1024 voltage and time values can be defined using external software tools.
