  • YL1-C40 series DHEN Type Type 2 Surge Protection Device AC SPD has Visual indication which shows Green (good)/ Red (repalce).

  • YL1-B60 series DHEN Type AC SPD Type 2 Surge Protective Device consisting of a base part and replaceable plug-in protection modules.

  • AC SPD Type 1 Voltage Limited Type Surge Protective Device is a type of surge protection device that is designed to protect electrical equipment from voltage surges and spikes caused by lightning strikes or other electrical disturbances.

  • In the most basic sense, when a transient voltage occurs on the protected circuit, an DC SPD limits the transient voltage and diverts the current back to its source or ground.
    To work, there must be at least one non-linear component of the DC SPD, which under different conditions transitions between a high and low impedance state.
    At normal operating voltages, the DC SPDs are in a high-impedance state and do not affect the system. When a transient voltage occurs on the circuit, the DC SPD moves into a state of conduction (or low impedance) and diverts the surge current back to its source or ground. This limits or clamps the voltage to a safer level. After the transient is diverted, the DC SPD automatically resets back to its high-impedance state.

  • High quality DC 3 phase Surge Arrester made in China.
    DC 3 phase Surge Arresters protect against lightning surge voltages in solar system (photovoltaic power supply system).
    These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection. Its installed location are recommended at both ends of the DC power supply line (solar panel side and inverter/converter side), especially if the line routing is external and long.
    High energy MOVs equipped with specific thermal disconnectors and related failure indicators.
