However, even after turning off the DC switch between the inverter and photovoltaic panels, there can still be 600 ~ 1500 VDC present. In the event of a fire, firefighters may be exposed to very serious potential hazards. 1. FIND THE RIGHT TIME TO EXTINGUISH THE FIRE 2. TURN OFF PV PANELS The PEFS series uses the PEDS switch and can be used directly with photovoltaic panels. 3. AUTOMATIC RESET When AC power is turned off (e.g., during a power outage) and then restored, the PEFS series will reset and reconnect the circuit quickly and automatically. The customer does not need to reset it manually each time. 4. NO ADDITIONAL NETWORK REQUIRED AND MORE STABLE ON-OFF CAPABILITY It simply uses the existing AC power system. Moreover, the PEFS does not perform on\/off functions via electronic components but through an isolation switch with arc extinguishing function, which disconnects the DC circuit directly with much greater stability. 5. EXTEND THE LIFE CYCLE OF PV INVERTERS This significantly extends the life of PV inverters and makes repair or replacement of PV inverters safer. 6. USE POPULAR DC SWITCHES The Projoy PEFS series is equipped with the PEDS switch, which is the most popular DC switch worldwide for photovoltaic applications. The response time of the Projoy spring rebound mechanism is only 5 milliseconds, which can quickly extinguish arcs. For this reason, PEDS has been chosen by many PV inverter manufacturers as the preferred DC switch. 7. Projoy has extensive experience in designing DC switches and has customers worldwide.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIf the customer wants the entire roof to reach an even lower DC voltage (e.g., below 80 V ~ 120 V), multiple safety switches (one for every 2-3 panels) can be used to ensure maximum safety.\u003c\/li\u003e\n\u003cli\u003eAS A PROFESSIONAL DC SWITCH MANUFACTURER\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIn case of fire, after turning off the AC circuit, the quick disconnect switch will automatically turn off and isolate the photovoltaic panels, allowing firefighters to eliminate the risk of high voltage from the photovoltaic panels on the roof and gain valuable time to handle the incident.\u003c\/li\u003e\n\u003cli\u003eIn case of fire, the firefighter safety switch can quickly turn off the photovoltaic system without the risk of high DC voltage.\u003c\/li\u003e\n\u003cli\u003eWhen installed in the system, the Projoy PEFS product will automatically turn off the DC circuit in case of AC power loss, e.g., during power outages, power line maintenance, or grid failure.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003eFire Safety Switch PROJOY PEFS-EL40H-10 But if firefighters turn off the AC power before extinguishing the fire, the PEFS safety switch series will detect a grid failure, and after 5 seconds, the PEFS will automatically turn off the isolation switch. Since this safety switch is installed close to the photovoltaic panel, the DC current in the building is disconnected, creating a safe environment for firefighters, reducing potential damage, and ensuring the safety of the photovoltaic system. FIREFIGHTER SAFETY SWITCH PROJOY EFFECTIVELY ENSURES PV SYSTEM SAFETY The PEFS firefighter safety switch series complies with the international standard firefighter operating procedure. The Projoy PEFS firefighter safety switch series resets automatically. Compared to ordinary quick isolation devices using remote communication technology on the market, the Projoy PEFS firefighter safety switch is directly controlled by the AC circuit and does not require an additional network. Combined with self-cleaning contacts, the switches have increased durability and safety. Projoy became the first company in China to develop physical isolation with DC arc extinguishing capability without using remote communication technology, effectively ensuring the safety of high DC voltage roofs.\u003c\/p\u003e","brand":"KRAFT\u0026DELE","offers":[{"title":"Default Title","offer_id":56331827577164,"sku":"EL40H-10","price":385.47,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/1684\/5388\/files\/24041.jpg?v=1766798519","url":"https:\/\/ostuklikk.ee\/en\/products\/el40h-10","provider":"OstuklikkB2B\/B2C","version":"1.0","type":"link"}
