ABB PCS100-AVC40 Active Voltage Conditioner
The ABB PCS100 AVC-40 is an inverter based system that protects sensitive industrial and commercial loads from voltage disturbances. Providing fast, accurate voltage sag and surge correction as well as continuous voltage regulation and load voltage compensation, the PCS100 AVC-40 has been optimally designed to provide equipment immunity from power quality events on your supply network.
Continuous protection from the most common utility voltage problems found in modern power networks.
Even the most modern power networks are not perfect and voltage sags are the most common cause of equipment malfunction in today’s automated industry. The PCS100 AVC-40, built on a proven and dependable converter platform, provides instant voltage sag and surge correction, ensuring maximum productivity.
PCS100 AVC-40 Correction Capabilities
The PCS100 AVC-40 responds to voltage sags or swells within several milliseconds and can inject up to 40 percent voltage correction. If a facility was faced with a voltage sag to 60 percent of nominal voltage the PCS100 AVC-40 would boost the voltage back to 100 percent. Voltage sags with 50 percent of nominal voltage are corrected back to 90 percent. No process interruption, no equipment would trip, just business as usual.
Performance is even better for single phase sags (the most common type), voltage sags down to 45 percent of the nominal voltage are fully corrected
In case of deeper voltage sags, The PCS100 AVC-40 undertakes a partial correction, which will often prevent loads tripping. In addition, it is able to continuously correct voltage fluctuations of ±10 percent of nominal, remove imbalances and mitigate flicker from the supply voltage.
How it works
The PCS100 AVC-40 consists of two converters that are not on the current path between the load and the utility. Instead, the corrective voltage injection is achieved by means of a transformer winding between the utility and the sensitive load. This configuration results in a very efficient and effective method to provide voltage correction with reduced risk of negative impacts on the load.
The PCS100 AVC-40 requires no batteries as it draws the additional energy required during sag to make up the correction voltage from the utility supply. With no ongoing maintenance costs typically associated with batteries the cost of ownership for PCS100 AVC-40 systems is very small.
Furthermore, the PCS100 AVC-40 contains a redundant internal bypass system that, in the event overload or internal fault condition, ensures that the load is continually supplied from the utility.
