UPS systems play a very important part in an overall power protection plan. They are designed to provide good clean uninterruptible power to critical equipment. They provide no protection for the communication and control lines found in today’s network type environments. They also do not normally provide AC power protection to the many nodes connected within the network. The surge protection elements found within even a very large UPS is very small in comparison to stand-alone SPD’s. Normally around 25 to 40kA. In comparison, our smallest AC entrance protector is 70kA and our largest is 600kA.
