+[[http://www.ztex.de/usb-fpga-2/|Series 2 FPGA Boards]], Experimental Boards, Power Supply Modules and USB-FPGA Modules 1.15x and 1.15y are supplied by a wide range input voltage of typically 4.5V to 16V. (Refer to the product specification for actual values)
-All products are equipped with with a standard DC connector with 5.5mm outer diameter and 2.1mm center pin diameter. The center pin is the positive pole, the outer contact is negative pole.
+Most of these products are equipped with with a standard DC connector with 5.5mm outer diameter and 2.1mm center pin diameter. The center pin is the positive pole, the outer contact is negative pole.
 The following rules have to be considered for the selection of the power supply:
-  * The peak voltage of the power supply must be less than 16 V (absolute maximum: 18 V) and the minimum voltage must be at least 4.5V. Any power supply within that range can be used. The current requirement depends from the product and the application.
+  * Output voltage must be within the specified range.
   * If non-stabilized power supplies are used, it must be ensured that the peak idle voltage is within the valid range.
   * Stabilized power supplies are save if they are within the valid range. Switching supplies are always stabilized, stabilized transformer based supplies are usually labeled with "stabilized" or "regulated"
