Ultra low noise pluggable PSUs

Originally developed as a custom solution for highly sensitive electronic measuring equipment designed to capture experimental ring accelerator data, the new Eplax 3U 7HP 19" pluggable PSU with output noise levels below 4 mV p-p is now available as a standard product through Verotec Inc. for any high sensitivity application where ripples and spikes on the output voltage must be as low as possible.

The dual output AC/DC power supply unit is rated at 45 Watt, with outputs of +15 V/ 1A and +24V/ 1.2A. A special filter network for the output rails reduces ripples and spikes to the absolute minimum without violating the unit’s slimline 7HP width. The quality and stability of the delivered output voltages are extraordinarily high; the noise voltage for all loads from idle to full load is lower than 4 mV p-p. Using the filtering technology developed for this design, ultra low noise power supplies with other outputs can also be supplied.
