Prosurge's PCB soldered Thermally Protected MOV is TUV approved PV surge protective device per IEC61643-31
We are hornor to announce that Prosurge's global patented Thermally Protected MOV ( PTMOV) now get TUV certificate as per IEC61643-31 standard for DC PV Surge Protective Device.
Prosurge thermally protected MOV is also be UL1449 4th listed Type 1ca SPD. This thermally protected varistor can be used for PCB mounting for both AC and DC PV surge protection.
Nowadays, Photovoltaic systems (PV System) range from small, rooftop-mounted or building-integrated systems with capacities from a few to several tens of kilowatts, to large utility-scale power stations of hundreds of megawatts, and in the meanwhile the potential impact of lightning events increases with PV system size. Where lighting occurrences are frequent, unprotected PV systems can suffer repeated and significant damage to key components. This results in substantial repair and replacement costs, system downtime and the loss of revenue.
This DC PV used thermally protected metal oxide varistor design with thermal protection designed to open in the event of overheating due to an abnormal over-voltage or temporary over voltage (TOV) and will interrupt any abnormal current that may be encountered.
This thermally protection MOV pass short circuit currant test Isscr 1000A per IEC62643-31, which is very compatitive SPD component on PCB surge protection.
Fuse or circuit breakers are mostly use in electrical systems as back up protection. Yet these devices have a long response time and high tripping current. But the MOV breakdown is in milliseconds, fuse or circuit breakers cannot provide protection in time.
In the PV inverter, when the SPD component is short-circuited by breakdown, our thermally protected MOV can withstand a 1000A short-circuit current and with self-safe design, Prosurge PTMOV can disconnect itself and will not cause fire problem.
Prosurge's TPMOV surge protection module has very compact size and space efficiency, is easy to integrate on printed circuit boards (PCB) and close to sensitive electronic element inside device, to minimize the potential impact of lightning events.
This TPMOV is PCB mount modular SPD, with surge capacity 25kA , voltage from 48Vdc to 1500Vdc available, can meet requirements of all applications for compatible with reflow and wave soldering procedure.
