The Hitachi Energy's Dynacomp low-voltage thyristor-switched capacitor banks are used for ultra-rapid transient free power factor compensation due to fast varying or large low-voltage connected loads, giving additional benefits of transient-free compensation and voltage dip minimization. With Hitachi Energy's Dynacomp technology large capacitor steps can be connected to the network very fast. By using a step-up transformer the Dynacomp can be used for capacitive compensation in medium-voltage installations too.

The Dynacomp low-voltage thyristor-switched capacitor banks can be used in any applications requiring short response times, large number of operations, transient free switching or large amount of reactive power. For example:

• Spot welding machines
• Rolling mills and big presses with fast switching loads
• Cranes
• Lifts
• Rubber mixer
• Saw mills and tunnel drills which have very high switching rates

Hitachi Energy has a vast experience in compensating fast reactive loads in the harshest environments. As a result, the Hitachi Energy's Dynacomp boosts high reliability and comes with:

• Ultra-rapid power factor compensation
• Usable in the harshest environments
• Equipped with detuning reactors for optimal protection against harmonics while still giving filtering effect
• Single and three phase models available
• Transient-free switching
• Very high number of switching operations possible thanks to power electronics switches
• Modular and compact standardized design
• Easy to install and extend
• Advanced communication features with Modbus
