Amity® Audio Building Blocks: ABB_-_
|
Our Amity® ABB_SPS_ power supplies
cost less than $ 68.00 (Euro 49.00).
ABB_SPS_ Amity® Audio Building Block _ Symmetrical Power Supply, the
ac power input side is shown here. Amity® ABB_SPS has a very low impedance
0 Volt middle and +/- 12V symmetrical outputs. This power supply is used with
Amity® amplifier building blocks It can deliver up to 1 ampere impulse
current and provides a very low impedance 0 Volt middle reference tap for
extremely low ground noise in Amity® ABB_ building block amplifiers. The
ABB_SPS has a maximum power (rms) of 3 watts and and has a UL approved, short
circuit proof transformer. Sinus rms output current is 350 milli-ampere peak
for +/- 10 Volt.

ABB_SPS_ Amity® Audio Building Block _ Symmetrical Power Supply, ac
input view. 2 standard 1.3 mm pins are for connection to 230V or 115V AC power
(option: can also be direct wired with lengths as wished). Four mounting
holes are provided in the corners for mounting in housings or on a motherboard.
The mounting holes are located in a square, 40 mm pro side (1.575 inch). Note:
the mounting holes are connected to the low impedance 0V middle tap. The Mounting
holes have 3.5 mm diameter.

ABB_SPS_ Amity® Audio Building Block _ Symmetrical Power Supply, the dc
power output side is shown here. Mount this power supply on spacers to maintain
the allowed air distance between the ac input on the bottom and the housing (or
mother board). AC and DC are seperated from each other on the board by 8 mm spacing.
which is ok up to 250V difference. We recommend using 10 mm spacers to mount the
ABB_SPS.

ABB_SPS_ Amity® Audio Building Block _ Symmetrical Power Supply, the
dc power output side is shown here. Four standard 1,3 mm pins are used for
connecting the +12V, 0V, and -12V dc power to your Audio circuits (option: can
also be direct wired with lengths as wished). The outputs are protected for
overvoltage surges. Output short circuit current is limited by the coil resistance
of the transformer which is garanteed by the transformer manufacturer.
