Kestrel 3kW Voltage Limiter

Voltage limiter for Kestrel wind turbines used in grid-tie applications.

Detailed Description

Sustainable/renewable energy sources such as wind turbines and hydro-generators are often connected to a gridtie inverter. Such inverters can enter operational modes that reduce the demand or disconnect the system from the generator. Any operational generator or alternator will exhibit high output voltages when no output is demanded.

The Kestrel Type 0704 voltage limiter uses electronic means to restrict the incoming voltage to the inverter at a pre-designed value. The product uses linear technology causing no electrical disturbance during operation. This quality is paramount when powering any communication or computer equipment.

The voltage limiter is passive and uses no energy whatsoever during normal operation. If for any reason the generator voltage rises, the limiter restricts this voltage rise to a maximum value. It achieves this limiting by simulating an electrical load on the generator.

The product is housed in a steel enclosure for wall mounting. It is extremely reliable in operation and incorporates a failsafe design. Unit cooling is achieved by convection and assisting fans.
