DC SPD is cost-effective and provides a solution to improve the system and eliminate any damage caused by surges. It is highly suitable for any facility. It can be used anywhere in the house for protection. These are installed on circuit breakers and automatic transfer switch for portable generator in residential homes and other places like pad-mounted transformers.
ZHEJIANG YUELONG offers and sells DC SPDs in 2 categories, type 1 and type 2.
Background While small solar panels used for battery charging and similar tasks may not require special connectors, larger systems normally connect the panels together in series to form strings. In the past this was accomplished by opening a small electrical box on the back of the panel and connecting user-supplied wires to screw terminals within. […]
To choose the best technology for surge protective devices, we should consider the following technical parameters (include but not limited to): 1. Type of surge protective devices according to EN61643-11/IEC 61643-11 2. Nominal Voltage (Un) 3. Maximum Continuous Operating Voltage (Uc) /Maximum Continuous Operating Voltage for PV System (Ucpv) 4. Voltage Protection Level (Up) 5. Nominal Discharge Current (In) 6. Maximum Discharge […]
