Abstract: Tejas offers two basic chart changers, namely, pneumatic and electric powered. In the instance of the pneumatically powered chart changer (Model P250) any available, although reasonably clean, air or gas supply of 50 psi may be used as an actuating medium. On the other hand the basic electric chart changer (Model B-2) draws power from a 12 volt battery. Considering these batteries are rechargeable, batteries may be exchanged as necessary to allow offsite recharging. Where AC power is available, the basic battery changer is available with an added trickle charger (Model B-2-E) to float the battery to overcome the periodic necessity of recycling batteries. The addition of the trickle charger to the package differentiates between the battery changer and the AC-powered changer of the electric types.
