To protect your valuable point motors on your layout.
Recommended power supply is 15 to 20 Volt AC with a power rating of 2 to 3 Ampere (most laptop charger will be efficient).
Capacitors recharge in a fraction of a second (2 x 4 700 microfarad capacitors).
Will throw more than 3 undertable point motors (Peco and Hornby) at the same time.
Also known as a capacitor discharge unit.
Complete installation instructions included.
Hint: Mount this circuit board as close as possible to the point motors to minimize wire lengths.
Warning: This is NOT A TOY and should be kept away from children.
