ABPSM-ULNA Ultra Low Noise Power Supply Module

Abracon Corporation's ABPSM-ULN-A solution provides an ultra low noise power supply source (25 nV / √Hz @ 1 kHz) with four regulated DC outputs. Offering 1.8 VDC, 2.5 VDC, 3.3 VDC, and 5.0 VDC bias ports, this module is uniquely positioned to replace multiple, low noise, linear power supplies, which are typically needed to bias noise sensitive circuitry.

The ABPSM-ULN-A is designed to utilize a universal low noise AC adapter, enabling worldwide functionality, accepting 100 VAC to 240 VAC and 50 Hz and 60 Hz cycles. Coupled with state-of-the-art low noise regulation, this power supply module (PSM) provides an optimal setup to conduct noise sensitive measurements of system critical circuitry, such as phase noise, jitter, spectral purity, and signal to noise ratio.

  • AC adapter input voltage 100 VAC to 240 VAC; 50 Hz and 60 Hz cycles - worldwide capability
  • Current sourcing capability 120 mA maximum each port
  • Convenient, ultra low noise solution offering most common bias levels
  • Ultra low noise < 25 nV/ √Hz @ 1 kHz offset
  • Four DC output ports, 1.8 V, 2.5 V, 3.3 V, and 5.0 V
  • Portable and lightweight
  • Low cost
  • Ideal for testing circuits including:
    • Audio
    • RF
    • Microwave
    • Medical diagnostic
    • Jitter sensitive digital
  • Lab grade power supply designed to replace bulky and noisy power supplies for everyday use
  • A must have for noise sensitive measurements such as S/N ratio, spectral purity, jitter, phase noise, and harmonic distortion.
