Welbor Technology's Wide Input Voltage Power Supply Boards are designed for use with our Brushless Motor Controllers, but can be used in any application where a reliable, high temperature power supply board must provide logic and signal level voltages. Its input voltage range of 100-400 VDC is ideal for those applications where the goal is to provide maximum power down a long cable. Lower input voltages are also available, as long as the upper voltage is a factor of four or less times the minimum operating voltage.
