Digi-Key Corporation Announces Stock on the ABPSM-ULN-A Power Supply Module from Abracon

THIEF RIVER FALLS, Minnesota, USA - June 18, 2010

Electronic components distributor Digi-Key Corporation, recognized by design engineers as having the industry's broadest selection of electronic components available for immediate shipment, today announced it has stock on the ABPSM-ULN-A ultra low noise power supply module from Abracon Corporation.

  • ABPSM-ULN-A (Digi-Key #535-10307-ND) Power Supply Module, 4-channel, Low Noise

This new product is now available for purchase on Digi-Key's global websites and will be featured in future print and online catalogs.

The ABPSM-ULN-A module provides an ultra low noise, power supply source (25 nV/√Hz maximum & 1 kHz) with four regulated DC outputs. Offering 1.8 V, 2.5 V, 3.3 V and 5.0 V 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.

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.

Features of the ABPSM-ULN-A include 100 VAC to 240 VAC AC adapter input voltage; 50 Hz and 60 Hz cycles; four DC output ports – 1.8 V, 2.5 V, 3.3 V and 5.0 V; current sourcing capability per port 200 mA max. (each port); and ultra low noise characteristics to include < 0.30 µVrms over 0.1 Hz to 1 kHz bandwidth and a typical Noise Density & 1 kHz offset per the following profile:

  • 4 nV√Hz for 1.80 V DC Output; 5 nV√Hz for 2.50 V DC Output; 7 nV√Hz for 3.30 V & 15 nV√Hz for 5.00 V DC Output
