Weiss PSU 102 Power Supply
List Price: $2,695.00
Use with the DAC204! Cable included.
The Weiss PSU102 is a universal non-switching, analog pow-
er supply. The voltage regulator circuitry is built with
discrete components. It is very low noise but still ca-
pable to drive complex loads.
The mains transformer has a toroidal core for low ra-
diation and low noise. The housing uses a double
frame consisting of an external aluminium shell and an
internal stainless steel frame for shielding and safety.
The integrated heat-sink is oversized by a decent

or 230V), a power on/off switch and a prima-

are wired in parallel. The sockets are made by
the Swiss company Fischer and are of a very

voltage regulator of our own design is used.
The voltage regulator circuitry is very low
noise but still high speed in order to quickly
follow high frequency load fluctuations. The
electrolytic capacitors are low ESR types.
The toroidal mains transformer ensures low
magnetic radiation and low noise operation.

twin metal frame. The inner chassis is made
of steel and acts as a very effective shield
against electrostatic and electromagnetic ra-
The outer frame is made of massive anodized
aluminium for additional shielding, resulting

The PSU102 is a universal, non-switching, analog power supply. It is designed to provide clean and quiet power to the finest hi-fi devices.
It is very low noise but still capable of driving complex loads.
Our design uses a discrete, non-switching, linear voltage regulator. The voltage regulator circuitry works at a very high speed in order to quickly follow high-frequency load fluctuations.
The electrolytic capacitors are low ESR types. The toroidal mains transformer ensures low magnetic radiation and low noise operation.
inputs and outputs
The unit has one IEC-type power input with an input voltage selector (nominal 115V or 230V), a power on/off switch, and a primary fuse.
There are two output sockets that are wired in parallel. The sockets are made by the Swiss company Fischer and are of very high quality.
The output voltage can be set to 5V, 6V, 9V, or 12V. The output current rating goes to 1.5A both outputs combined. The outputs are short-circuit proof.
Mains Voltage: 100-120 / 200-240 Volt.
Fuse rating: 500 mA slow blow at the 115V setting and 250 mA slow blow at the 230V setting.
Power consumption: 30VA max.
OUTPUT VOLTAGE and CURRENT
Output voltages selectable: 5V, 6V, 9V, 12V.
Output current: Up to 1.5A with the two sockets combined.
Two Fischer brand two-pin sockets, wired in parallel. The corresponding Fischer plugs are S 102 A051-130+ with the E3 102.5/3.5 cable clamp.
