When properly installed, UPS and battery backup systems serve as rugged devices that don’t require much attention, that is, until they start to age. Two to three years after installation, UPS become less reliable. Batteries can fail and hot spots of unattended connection in the electronics distribution system can become a serious problem. Additionally, harmonics increase and load characteristics can change. Just how old is your power protection equipment?

Have you checked your power sources lately? This would include city power and internal building power distribution. Battery backup equipment relies on the proper current from these sources. Can you recall the date of the last power quality survey or power study at your facility?

The best way to protect your electrical equipment from damage is to schedule routine maintenance of all battery backup equipment and power sources. TCS can manage this process for you. Our technicians are licensed and certified to repair and maintain more power protection equipment than any other company in the area. So, even if you have purchased your equipment elsewhere, TCS can design a cost-effective maintenance program to fit your particular needs:

  • Total system responsibility: one point of contact for all of your various manufactured power products, such as UPS, batteries, Generator Sets and switchgear
  • Monthly, quarterly, semi-annual and annual routine maintenance
