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 up to three connected instruments by a single SPD level 4 surge immunity: up to 4 kV surge protection (IEC 61000-4-5 level 4) passive device: no power required for protective functionality reliable in harsh conditions: rugged, weatherproof (IP66) housing for outdoor environments industrial-grade: designed for Hukx-brand “industrial pyranometer and diffusometer” series 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 without SPD01) for Industrial Environments according to IEC 61326-1 and IEC 61000-6-2.
