SV Series - Stand-Alone Electronic Products

The SV Series Positioners were designed specifically for use with Exlar rotary and linear actuators to control valves and dampers in process control applications. The all-electric design eliminates the complexity of applying electro-hydraulic interface pilot valves or electric-pneumatic positioners, and provides two-way communication between your system and the actuator. The fully digital SV Series Positioners operate from standard process control inputs allowing for simple retrofits of hydraulic or pneumatic actuated valve applications or dampers. SV Series Positioners used with Exlar's high performance linear and rotary actuators can also replace fluid power and low performance electric actuators, eliminating problems associated with actuator failures.

Pitch Servo Drives - PITCHmaster II+

The exceptionally rugged Moog PITCHmaster II+ Pitch Servo Drive was developed specifically for the harsh operating conditions found in the rotor hubs of wind turbines. With its high level of integration, the Servo Drive simplifies axis box design, decreases its volume and reduces wiring complexity. Due to its certified safety equipment, the drive fulfills the current safety standards and thus simplifies the certification process for wind power turbines.Electrical pitch systems with PITCHmaster II+ Servo Drive models are suitable for installation at altitudes up to 3,000 m and internal axis box temperatures from -30 up to +70 deg C. The innovative features of this Servo Drive include intelligent intermediate circuit pre-charging, which protects the slip ring against excessive charging currents and permits optimized fault-ride-through operation.

Servo Drive with a high overload capability, available in 2 device sizes: - E40 with 40 A nominal and 100 A peak - L60 with 60 A nominal and 200 A peak
