Power supplier - Quasar
Bi-Directional Power Supply for Motion Systems
The Quasar series rectifier from Prodrive Technologies is a cutting-edge power solution designed for seamless integration with advanced servo drives like the Cygnus D3-400/4. Engineered for high performance and efficiency, the Quasar rectifier ensures stable power delivery while reducing operational costs.
What sets the Quasar apart is its bi-directional power flow capability. This means that instead of dissipating regenerative energy through brake resistors - a common approach in traditional systems - the Quasar sends this energy back to the AC power source. This feature not only improves energy efficiency but also simplifies the system architecture, making it less complex and more cost-effective. By eliminating the need for external brake resistors, you reduce component count, save space, and lower maintenance requirements.
