The SPPVR family of surge protection devices (SPDs) is our answer to the growing need for safe and reliable photovoltaic (PV) installations in residential and commercial buildings.

Powerful protection is the first step to ensuring a long lifetime for your equipment and inverters: these SPDs ensure that your system will not be damaged by any overvoltage event on the direct current (DC) side of your PV application.

The SPPVR products can be deployed in residential settings, for example in small combiner boxes or commercial applications such as array protection boxes in PV fields. SPPVR offers a future-proof portfolio for all possible use cases.

E-T-A Power relays are reliable problem solvers when it comes to switching high currents. Particularly construction machinery, agricultural vehicles as well as buses and trucks, floor-borne vehicles and other special vehicles (e.g. fire brigades) often have connected large electrical loads. In these applications, power relays disconnect the entire on-board electrical system from the battery.

Depending on the application, E-T-A offers purely electro-mechanical relays, solid state relays and also a hybrid design consisting of an electro-mechanical switching system with an intelligent electronic control unit.

Key Product Lines & Features

• EPR10 Solid-State Relays: Designed for high continuous currents (up to 200A at 24VDC), requiring 80% less space than traditional alternatives and
  eliminating the need for separate heat sinks
• HPR10 Hybrid Relays: Combine robust mechanical, bistable switching with intelligent electronic controls, enabling features like on/off delays and voltage
  monitoring
• MPR10/MPR20 Mechanical Relays: Bistable (MPR10) or monostable (MPR20) relays designed for high current switching with low power consumption

Key Advantages

• Efficiency: Very low holding current reduces power consumption.
• Durability: High resistance to environmental factors (IP57 rated for some models).
• Maintenance: Long service life with reduced maintenance costs due to solid-state technology.
• Functionality: Options for built-in overcurrent, short-circuit, and thermal load protection.

Applications

• Battery Management
• Power Distribution
• Circuit Protection in Harsh High-Load Environments
