DS210DC off-grid surge arrestor
The Citel DS210DC series is designed to protect 12V, 24V, 48V and 150V DC power lines for an off-grid PV system. The maximum voltage should not be exceeded in any conditions. Use the next higher rated unit if necessary. The surge protectors protect the charge controller and other system electronics. DS210DC automatically reset after each lightning surge or electrical transient. These surge arrestors clamp at much lower voltage than Delta surge arrestors at left so they offer much better protection for charge controllers and inverters in low-voltage DC systems.
