Lumin D2/U1 mini – low noise PSU

Description

Upgraded super low noise power supply v.3. for Lumin D2/U1 mini streamers (includes PSU connection adapter).

It is an evolution of the previously built low noise power supply. Built with high-quality discrete components, it provides clean, interference-free power to your devices. Made in a black steel housing with integrated IEC socket with switch and fuse. It is only compatible with 220 – 240V networks.

PSU specification:

• • special housing construction isolating the transformer and the AC part from the electronics and the regulator
  • dedicated 70VA toroidal transformer with increased amount of copper
  • large capacity of the input filter – over 22000uF
  • two stage voltage regulation with a soft start procedure, and additional ripple filter
  • high PSSR, low noise floor: -148dB to -176dB in the range from 100Hz to 100kHz
  • low noise level: <4 uV AC RMS for the 0-20kHz frequency band (6 uV in the 0 to 100kHz range)
  • low Peak-Peak voltage: <50uV
  • maximum allowable current 2.5A
  • set includes an OFC 4N IEC cable (EU plug 3 x 0.75mm) and a DC cable on the GX16 connector.
  • output voltage: 12V (optional regulation from 12 to 13V)
  • dimensions: 120 mm width, 53 mm height, and 215 mm depth
  • weight: 1.7 kg

PSU adapter:

• • it replaces the factory power supply with a 230V socket

All measurements were made with a current load of 1A. The power supply is characterized by a constant noise level up to 2.5A load. Each power supply is tested before shipment and has individual ripple and noise measurement results attached to it.
