Ultra Low Noise Power Supply Module Noise (0.1Hz to 10Hz) Abracon’s ABPSM-ULN-A solution provides an Ultralow noise power supply source (25 nV / √Hz @ 1kHz), with four regulated DC Outputs. Offering 1.8V, 2.5V, 3.3V and 5.0V DC bias ports; this module is uniquely positioned to replace multiple, low noise, linear power supplies which are typically needed to bias noise sensitive circuitry. ABPSM-ULN-A is designed to utilize a Universal low Noise AC Adapter, enabling World-Wide functionality, accepting 100VAC~240VAC; 50Hz and 60Hz 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 S/N (Signal to Noise ratio).
