Notes: 2hp Power supply + Dual Passive Mult

Portable 2hp power module for compact skiff cases with dual passive multiples

12 to 20V DC input
Up to 1A from +12V
Up to 700mA from -12V via flying bussboard

Power consumption:

0 mA +12V
0 mA -12V
0 mA 5V

Dimensions:

2 HP
42 mm deep

Notes: Switchy is a module that allows you to turn on or off up to three modules (or busboard) independently of each other.

No need to turn off the whole case: All three voltages (+12V, -12V, 5V) are interrupted at the same time.

Used to reduce the background noise of certain "noisy" digital modules when not in use, to initialize certain modules or change their function, to change an SD card, to relieve the power supply with energy-consuming modules, etc.

Dimensions
6 HP
30 mm deep

Current Draw
20 mA +12V
20 mA -12V
20 mA 5V

Notes: This is a revision 02 of ADDAC's Power Starvation module.

It provides an "ideal" way to power starve other modules, starving modules means the modules will receive less voltage than the standard +/-12V supply.

Power starvation is the first hack that any "DIY'er" learns. It's also one of the hacks that can generate some of the most interesting sonic effects in circuit bending.

Plug any module below +/-200mA through it and independently tune it's supply power. This will have most interesting effects in analog modules: filters, delays, mixers... They can either go silent or start screaming at your ears, going berserk with the lack of current to behaving normally, making them cough, choke... Something like a safely induced heart attack...

While revision 01 was a simple circuit with pot working as a voltage divider, this upgraded version uses a DC to DC converter that receives its input from the +12V power rail and outputs a bipolar 15V supply. This DC-DC converter also offers short circuit and overcurrent protection. The +/-15V lines are then sent through variable analog voltage regulators that can output a range of 2.5V to 13.5V.

In other words, the module features a +/-200mA PSU with variable voltage outputs.

Safety disclaimer:

While using ADDAC300 should be safe for any module, there may be specific modules where its use may not be advised.

!! Use at your own risk !!

ADDAC System won't be responsible for any issue that may arise while using ADDAC300 power starvation.

If in doubt contact ADDAC prior to any connection.
