The Types of Power Supply Available for Stair Lifts

Stair lifts require power to operate and there are two main sources of power for these lifts. There is the AC power, also known as the alternating current. These types of stair lifts always have power because they are plugged into the wall. Those stair lifts that operate with DC power, or direct current, use batteries capable of being recharged. In years past, the most reliable power was supplied through the power of alternating current, or AC. That has changed however, with the constant and consistent upgrades of the technology that builds and supplies direct current power, or rechargeable batteries.`

Those stair lifts powered with direct current have become more user friendly with the advanced technology used to build the batteries. These easy to install and maintain lifts have become more popular and more widely used in recent years.

DC powered stair lifts can be recharged easily by plugging the lift into a nearby outlet when it is not being used. This allows the 120V power to be transformed into the 24-38V battery. These battery operated stair lifts can then make up to 24 runs either up or down the lift before recharging is needed again. This is especially comforting to those who use the stair lifts because they know that the power will not quit in the middle of a blackout or other type of power outage.`

A particularly helpful feature of the stair lifts is the copper strip attached to the top and bottom of the track upon which the lift glides. The chair itself has charger points that pull power from the friction caused by running the chair across the copper strips, thus recharging the battery even while it is in use. If the connections are not properly charging the lift, a beeping noise that is usually heard when the stair lift is operating will not be heard. If that happens, the best thing to do is call the person who services your stair lift so that it can be checked.

Some stair lifts still have the AC constantly operating and charging the system. It does this by using a lower 24-28 voltage of power which steadily charges the lift and effectively eliminates the points on the chair or the copper strips on either end of the lift.

There are, of course, advantages and disadvantages to both types of systems. Stair lifts with copper strips and points automatically means that the system has more parts to it. These parts will need to be cleaned and/or adjusted periodically for best operation. The user of the stair lift will also have to insure that the lift is parked properly so that full charging takes place.

Stair lifts that use the direct current system, or the rechargeable battery system, use more moving parts. When a machine has more parts that move constantly, these have more of a chance to jam or break. There could also be wires inside the cable that might break.

With either system, the owner/operator of the stair lift will find that the advantages far outweigh the disadvantages of such a system. He or she will also need to understand that with these advantages comes the responsibility of making sure that the stair lifts are properly maintained.
