What is a DC Surge Protective Device？
DC Surge Protective Devices (SPD) are essential for safeguarding electronic systems from voltage spikes, ensuring both reliability and efficiency. Their ability to absorb and redirect excess voltage helps ...
• Quickly dissipate heat and reduce the service temperature
• Plug-in clips, Easy module replacement
• Flash Barrier, Prevent arc propagation in current impact
• Use a suitable electrical insulator to keep a 10mm min.safety distance from the PV-SPD and other grounfed parts in the housing
• The green and red visual indicator flags show the module protective status (green = good, red = replace)
• Features visual indication and optional remote contact signaling (floating changeover contact)
• Feature a combined disconnection
• Short-circuiting (shunting) device with safe electrical isolation to Prevent fire damage due to DC arcs.
