Speed control boards

Overview

Speed control boards

The board is designed to provide speed control and remote stop facilities to the 102FD/R and 313FD/D 12 V DC pumps, and is capable of accepting a remote speed control signal input from users' equipment. With the addition of extra components to the standard board, options of direction reverse, power on LED indication, 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 speed control board for the 102FD/R incorporates an on-board power transistor. The power transistor for the 300 series board is rated for higher loads, and must be mounted on an external heat sink with a 1,000 sq cm surface area.

Full connection and calibration instructions included and optional features requiring additional components are available.
