for digital pyranometers and diffusometers Give your solar radiation sensors the protection they deserve! SPD01 is an industrial-grade surge protection device for digital pyranometers and diffusometers. It reduces the risk of costly instrument damage and data loss by protecting up to three connected devices against high-impulse currents and voltages: surges. For example, seasonal lightning and inductive switching are common sources of surges in PV power plants. enhanced protection: increased protection of digital pyranometers, communicating over RS-485 multi-instrument coverage: protection of...

Level 4 Surge Immunity : High Impulse voltages and currents SPD01 is a surge protection device for digital pyranometers and diffusometers. The device combines and coordinates the protection of the power supply and the RS-485 serial communication lines. Protecting the pyranometer against electrical surges is very important to guarantee reliable operation in harsh “industry-grade” outdoor environments, such as solar photovoltaic (PV) power plants and meteorological stations. SPD01 is designed for use with Hukx’s industrial pyranometers and diffusometers, which are tested and classified (with and...

SPD01 properties In the electrically-harsh environment of PV power plants, SPD01 protects connected instruments from lightning- and power-switching-induced surge events. At the same time, it allows for a flexible system design. Properly installing the SPD01 near a Hukx industrial pyranometer or diffusometer ensures that voltages and currents reaching the sensor are strongly suppressed. Optional SMF01 for mounting on a vertical mast SMF01 is a practical metal bracket that helps with mounting a surge protection device on a mast. Flexible system design Provided that instruments are in close proximity...
