To help ensure the success of its shows through the entire production, a theater in Taiwan has ordered an ABB PCS100 active voltage conditioner (AVC-40) to be installed in the theater to protect the curtain control system. More specifically, the PCS100 AVC was utilized to control the smooth opening and closing of curtains during performances without causing any power quality issues. This decision followed a previous incident in the theater, in which they experienced many troubles with a system during rehearsals when the curtain would not rise. A reliable curtain control system is paramount for a professional performance.
The previously existing curtain control system within the theater, which had been manufactured by a European company, had a rated voltage was 400 V + -10%. However, the nominal voltage in Taiwan is 380 V, and since the theatre is located at the end of power feeder, the voltage here is approximately 370 V.
If the load increased during a peak period, the voltage would drop below 360 V and would therefore cause the stage curtain control system to abnormal in its functionality. Abnormal behaviors of a curtain control system can cause the curtain not to rise or lower when required during a show. It was then proposed to the customer that a PCS100 AVC could be installed to up the voltage to 400 V to solve this issue.
ABB’s PCS 1000 AVC 40
The compact size of the PCS100 AVC-40 is ideal for applications such as that required in the Taiwan theater.
The PCS100 AVC-40 has a small footprint. It can easily fit into equipment rooms or confined spaces, in this case near the dancer’s preparation area, eliminating the need to de- sign and build added floor space. This made the product more so the perfect solution.

With industry-leading efficiency that exceeds 98%, the PCS100 AVC-40 exhibits a minimal heat rejection, that results in minimal costs for electricity and cooling required by the consumer. The PCS100 AVC-40 does not require any batteries, since it draws the additional energy it requires to compensate for the correction voltage from the utility supply. With no ongoing maintenance costs that are often associated with the use of batteries, the cost of ownership for a PCS100 AVC- 40 system is very low.
