Power Supply Chain 1 provides up to 20 different voltage sources 2 USB 2 +12V and 8 + -9V Power terminals 

The Power Supply Chain 1 uses a rechargeable battery to power up  8 effects pedals as -9V is commonly used in guitar effects. The ampacity of the +- 9V  channel is +- 150mA. The idea is to replace 9V batteries whose voltage level is  unknown.  As their voltage gets low, they sound  bad and is seems to happen only during a gig, leaving the musician the need to test batteries during a show. 

See the product below performing its' intended function

The Power Supply Chain 1 is designed to keep your effects powered up for your whole show so you can concern yourself with playing and not changing batteries. 

Now, let's see the product in its' shipping container.

Notice the product provides a free uB charge cable, 2mm load cable and battery specification sheet.  The supply is wrapped in wax paper not plastic for environmental reasons.

                                                            Turning on the Power Supply Chain 1.

  Simply turn it over and press the button 1 time. To turn it off, press the same button quickly 2 times. It's that simple. Now, you're ready to go.

Battery charge status:

Observe 4 blue lights on, indicating fully charged battery.  If only 1 blue light  is illuminated, it's time to  recharge. The battery maintains its' 5 volt output, throughout the entirety of the charge cycle. This is a definite advantage of the Power Supply Chain 1. 

Changing Polarity to +9V

Now, let's learn how to select +9V in case you need it. Simply unscrew the silver screws and open the Power Supply enclosure. See the circuit board and move the jumper to the +9V selection on the circuit  board. See the Green light change to Orange. Now you have +9V selected. The light was put there only to remind you that you have + or - voltage selected. Reassemble supply. See below.

Overcurrent event:

 Note: incorrect bias, in other words, using +9V in a -9V application can cause many things to happen, and, none of them are good. Therefore, there is a resettable fuse to protect from an over current event. The fuse will open during the overcurrent event, the close itself, and normal operation will resume, after the problem has been corrected. Close up the supply and it's ready for use.

Recharging your Power Supply Chain 1

Now, let's learn how to recharge the Power Supply Chain 1. It's as easy as all the other functions previously described. See the picture below.

Recharge Mode:

The edge of the Power Supply  has a  slot to plug in a USB uB cable (provided in package). Plug the uB cable into an ordinary wall adapter, and into the wall outlet. Important: The power supply will charge in this configuration. However, it will charge much  faster if you press the green button on the front panel which disables the +-9V and 12V outputs as well as the top  USB output.) The bottom USB slot is still operable. (See picture below.)

Notice how the green channel lights are off and the yellow light is on. This means the PSC1 is in charge mode. To take it back out of charge mode, simply press the battery button 2 times to turn it off and 1 time to restart in normal operating mode. It's that simple. =)
