Tyco Electronics’ 2Pro LVM2P-015R10431 device is an integrated over-current/over-voltage/over-temperature circuit protection device that helps protect a wide variety of low-power systems against damage caused by over-voltage faults, including lightning strikes, ESD surges, loss of neutral, incorrect input voltage and power induction.
The RoHS-compliant 2Pro device combines a PolySwitch polymeric positive temperature coefficient (PPTC) over-current device with a metal oxide varistor (MOV) component into one thermally protected device to help provide resettable current limiting for over-current protection and voltage clamping during over-voltage events. It helps provide protection for AC mains LED lighting systems, PLC network adapters, cellphone chargers, AC/DC power supplies, modem power supplies, AC panel protection modules, AC power meters, white goods and home and professional appliances.
Although the AC line voltage applied to an MOV is not generally expected to exceed the device’s maximum continuous operating voltage rating, over-voltage transients may occur that exceed these limits. By integrating PPTC technology with the MOV, the 2Pro device improves over-current and thermal protection under conditions where the MOV is exposed to prolonged continuous over-voltage events. In the event of an over-voltage transient, such as a loss of neutral event, the PPTC element of the 2Pro device heats up, trips and goes into a high resistance state, helping to reduce the risk of MOV device failure.
