Hydraulic VVVF

With the demand for better ride comfort, hydraulic manufacturers have improved this product range with the introduction of VVVF hydraulic packs. Interfacing the various hydraulic companies’ preferred inverters with the hydraulic equipment being factory set, Lester Controls have fine-tuned these controllers to work in harmony with each and every make. With the valve blocks factory preset, installation is far easier as the process is already completed at the source.
