Our company was founded in 1992, with the original name ACER. It is a purely Czech company that develops and manufactures surge arresters and limiters for the protection of LV and HV power distribution networks and protects equipment against atmospheric and switching surges.

We have been supplying surge protection worldwide for more than 30 years. We have our own development, production, technical support and testing facility. We produce surge protectors not only for residential and non-residential construction, but also for a wide range of industrial applications. We develop and manufacture isolation guards for isolated IT networks.

We manufacture and sell charging and add-on modules or batteries. Based on your specifications, we will carry out a technical design and individual price calculation. We can also supply you with individual block components or custom products according to your needs.
