MOV 20D560K METAL OXIDE VARISTOR

Metal oxide varistor (MOV) are voltage dependent resistors with symmetrical voltage-current characteristics which are designed to protect all kinds of electronic devices or elements from switching pulse or induced lightening surges. Its non linear characteristic with broad application range, mass production feasibility are gardually being used in various level of electric and electronic device from low to high voltages level protection The normal type of metal oxide varistor are radial lead varistors (MOV) that are designed to be used continuously across AC line primary or DC circuit for transient voltage and surge suppression.APPLICATION?? Suppression of surge current in consumer electronic and industrial electronic. Such as LED Lighting, Energy,Meter, Switch, Power strip etc.??Suppression of surge current in communication and cable network equipment.??Surge protection on electronic equipments, which are set of Premises device, Gas and Oil facilities.? Suppression of internally generated spikes in electronics circuits.? Photographic Apparatus and so on which used as limiting voltage switch in photographic equipment.Metal oxide varistor

RoHS and Reach complaint
Max. allowable Voltage(AC): 11V~1000V
Max. allowable Voltage(DC): 14V~1465VOperating conditions1) The HEL varistors shall not be operated beyond the specified “working conditions temperature” in the specifications. The upper limit temperature of the varistor is 85?C or 125?C. For easy heating devices such as lights HEL varistor T type 125?C is recommended.?2) The HEL varistors shall not be operated beyond the specified “Maximum allowable voltage” in the specifications.?3) The HEL varistors shall not be subjected to surge currents beyond the “Maximum allowable voltage” in the specifications. In case of application to repeated surge/overvoltage, the HEL varistors shall not be subjected to surge currents and energy levels above the specified maximum rating in “impulse life rating” in the specifications. (refer to derating curves: the relationship between peak wave width, peak current value and pulse times)4) When surge/overvoltage is intermittently applied to the HEL varistors with short durations, the devices shall not be operated beyond the specified “Rated Wattage” in the specifications. Otherwise, the varistors accumulate more and more heat would lead to thermal breakdown.5) Power grid environmental requirements: the HEL varistors shall be impacted greatly by the electricity supply environment to the equipment including voltage stability, large electrical equipment around, buildings and low voltage distribution transformer well grounded etc.
