Momentary Out Of Stock

The Powertrain1250 is an extremely low noise DC pedal power system with 5 isolated sections. Isolated sections help break-up potential ground loops and lower the noise floor. Two isolated sections may be connected in series for higher combined voltages, or in parallel for higher combined currents. All outlets are tip negative 5.5 x 2.1mm output.

The First output is isolated and switchable for 9Vdc, 12Vdc, 15Vdc or 18Vdc and provides up to 150mA.

CAUTION!!! Some pedals are NOT designed to accept more than 9 Volts. Be very certain of your pedal’s power requirements before trying a higher voltage. We are NOT responsible for any damage caused if the wrong voltage is selected. Always unplug the power from your pedal before switching voltages!

The Next Three isolated outputs are set to 9V DC, provide up to 210mA each and have a Load Dependent Voltage (LDV) control. LDV has the effect of starving some pedals like a weak battery which may have desirable effects on the headroom, distortion, sustain and break-up of certain pedals.

With the LDV trim pot turn all the way up (fully clockwise) the voltage will be fixed at 9V DC. As the LDV is backed down, the impedance increases and the voltage will start to droop in proportion to the amount of current being drawn. Also, as the voltage droops the corresponding LED will start to dim. LDV is an Impedance (not voltage) adjustment. For example, if you were to use a high impedance volt meter to measure the output, you would see very little voltage drop no matter where you set the LDV. However, with a pedal connected as a load, the voltage would drop according to the pedal’s current draw. The complex nature of the impedance makes the LDV respond like a battery to soften up when certain pedals clip or draw more current according to your playing dynamics.

• At 100% LDV = Full Power Supply
• 95 to 100% = Fresh Alkaline Battery
• 90 to 95% = Fresh Carbon Battery
• 60 to 90% = Weak Battery
• Below 60% = Crazy New Discovery Zone

Note: Many pedals will not benefit from LDV depending on how they handle power internally so run it all the way up for those pedals.

The Last section consists of four paralleled outputs set to 9V DC which provide a total of 500mA. Use these to power all of your pedals that don’t mind sharing power with other pedals. These outputs can also be used with daisy chain cables to allow the powertrain1250 to run many more pedals. How many depends on your pedals collective total MA draw.

THE MAINS VOLTAGE SELECTOR selects between 115 (for 95 to 130V AC operation) or 230 (for 190 to 260V AC operation). Always unplug AC power from the unit before changing the voltage selected!

THE AC POWER INLET is paralleled with an IEC OUTLET to allow AC power to be daisy-chained to an additional powertrain1250 or adapted as needed (for example, to an outlet strip to provide for additional AC power requirements). The outlet is rated to supply up to 10 amps. The use of an IEC outlet allows for operation in 100V, 115V as well as 230V AC POWER markets.

CAUTION! COURTESY AC POWER IEC OUTLET WARNING! Keep in mind that the voltage you supply to input of powertrain1250 will be duplicated at the courtesy outlet. For example; when using the powertrain1250 in the UK with the selector switch set to 230v, the current power of the Output IEC will also be 230v!
