Charger Board (chrg.1)

Used 2003-2005

Overview

The charger board is designed to charge six NiCd batteries and provide power to the TekBots robot platform. It accepts either AC or DC voltages as input in the range of 10 to 24 volts. The board provides short circuit protection for the batteries and includes multiple sites for obtaining power directly from the batteries.

Features

  • Short circuit protection resettable fuse.
  • Power bussing.
  • AC-to-DC regulation.
  • Charge indicator light.
  • Slow and fast charge.
  • Power switch.
