Flexible solution for special applications!

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.

• Max. total output power: 130 W
• Max. voltage per channel: 5 V/30 V
• Max. current per channel: 2 A
• 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

Features & Benefits

Source/sink functionality

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

Modulation inputs

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 50 kHz. Applications include testing of AC motors, relays, etc.

Parallel & serial operating mode

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.

Arbitrary function

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.
