AVC RTS
The EMES AVC – RTS (Ride Through Storage) is designed for sag correction in commercial and industrial applications, providing a seamless power supply, eliminating downtime. The AVC – RTS is the ultimate solution for a complete protection from power outages, voltage sags and swells. All in a single, cost-effective and robust solution.
What is voltage sag?
A voltage sag is not a complete interruption of power; it is a temporary drop between 10-90 percent of the nominal voltage level. Voltage sags are the most significant and costly power quality problem facing industrial and commercial customers today. Many types of electronic equipment are sensitive to voltage sags, including variable speed drive controls, motor starter contractors, robotics, programmable logic controllers, controller power supplies, and control relays.
Customer benefits
Our clients report the cost of production stops can be as high as $40,000 per hour. Total production loss for a single event can exceed $1,000,000 or more. Pharmaceutical manufacturers, semiconductor manufacturers, food processors, automotive industry and other power-critical manufacturers report similar staggering costs. In addition, unmitigated voltage sags can cause data loss and equipment damage.

Operation Modes
The EMES AVC – RTS is designed for sag correction in commercial and industrial applications. It is our solution for a complete protection from power outages, voltage sags, swells and blackouts. All in a single, cost-effective and robust solution.
In the event of power outages or voltage sags, the AVC-RTS activates power protection mode. During this mode, real active power and real reactive power are provided to the loads, ensuring complete immunity to the mission critical processes from utility power interruptions, voltage sags and swells. This guarantees maximum system availability and reliability for mission critical processes.
Normal operation mode with the AVC-RTS in standby protection mode with the market leading > 99% high efficiency. Lowering ongoing costs of ownership compared to other solutions such as traditional UPS etc.
