BESPD-PV DC Surge Protective Device
The BESPD-PV DC Surge Protective Device (SPD) is a critical safety component specifically engineered for high-voltage direct current (DC) photovoltaic systems. Installed in DC electrical circuits, its primary function is to suppress transient overvoltages and safely divert high-energy lightning surges or switching overvoltages to the ground. By clamping the line voltage within the safe tolerance range of connected equipment, it effectively protects PV combiner boxes, inverters, distribution boxes, and other sensitive solar equipment from being damaged or destroyed by instantaneous high-voltage spikes.
Key Features
- Ultra-Fast Response & Low Residual Voltage: Features an exceptionally fast response time and low clamping voltage to ensure sensitive PV electronics are protected. Available in multiple high-capacity discharge current options (10kA, 20kA, 30kA, 40kA) to suit various protection levels in solar arrays.
- Modular Plug-In Design & Visual Status: Engineered with a convenient plug-and-play modular structure for easy maintenance and replacement without disrupting the entire system. Includes a visual status indicator for real-time monitoring, and is available in multiple pole configurations (2P/3P/4P) to adapt to diverse DC voltage specifications.
- Flame-Retardant Housing & Safe Failure Mode: Constructed with premium ABS/PC flame-retardant materials that withstand high temperatures without combustion. Features built-in short-circuit protection to ensure that if the SPD fails, it safely disconnects without causing a continuous short circuit in the main DC line.
