AMT SOW PS-4X100, a galvanically connected with the primary power module has four output voltages electrically connected by minus wires. The each output voltage can be set in one of four values: 9VDC, 12VDC, 15VDC, 18VDC. The module is designed to power guitar pedals consuming max 100 mA, such as AMT Electronics - preamps series LA, guitar effects FX, overdrive pedals DRIVE.
The polarity of the power module: minus on the inside, plus on the outside. This power supply is also suitable for other pedals with current consumption of less than 100 mA with the same polarity. The device is powered from the AMT SOW PS ACDC-18V primary power module or an external adapter with an output voltage of 12-18VDC and a current not less than consumed by all connected to it pedals.
The advantage of this power module is that when it is used in conjunction with other modular units it eliminates the need for different voltages and different current consumption. The application of this series module is important for powering pedal boards.The power supply modules are assembled into a single structure without additional cables and fixtures using the built-in connectors and mechanical locks. The output connectors are located on the opposite module’s sides; it helps to achieve easier commutation.
Case dimensions: width - 36mm / depth - 76mm / height 33mm. Weight 170 g
