The board is designed to provide speed control and remote stop facilities to the 102FD/R and 313FD/D 12V DC OEM pumps, and is capable of accepting a remote speed-control signal input from users' own equipment. With the addition of extra components to the standard board, options of direction reverse, power on LED, AC supply input, board-mounted speed control potentiometer and instant prime are available.
Two different boards are available, both in Eurocard format with a 32-way edge connector. The 100 series OEM speed control board for the 102FD/R incorporates an on-board power transistor, whereas the power transistor for the 300 series board is rated for higher loads, and must be mounted on an external heat sink. |
