Ptc Speaker Protection. RXE250 PTC Fuses - Speaker Protection RN3470 295 In stock. PTC Characteristics and Terminology A polymeric PTC positive temperature coeffi cient overcurrent protector is an element placed in series with the circuit or assembly to be protected. Tweeters Accessories Crossovers.
The most commonly used one is a disposable fuse and the protection requirements of the speaker system are relatively strict. Ceramic PTC thermistors are used instead of conventional fuses to protect electrical devices such as motors transformers etc. We use cookies to provide the best possible customer experience across this site through third party ads and analysis of web data.
It is designed to protect the speakers from damage caused by turn on pops misadjusted crossover frequencies or auto-calibrating processors that deliver a signal. Find my nearest store. Speaker Protection Devices at Parts Express.
Overcurrent protection for on-board DC motors When a motor is overloaded or rotation of a motor is stopped locked an overcurrent flows through the motor. They behave somewhat like a cross between fuses and bulbs. Low cost speaker protectionMore specifications ensure accurate choice for better protection.

Maintenance can be complex and downtime is just not an option. How a PTC works. Applications of PTC thermistors for overcurrent protection Application.
Polyswitches will protect against electrical current o. The purpose of this auto-rearmable heat fuse is to cut the flow of the current or to derive when its temperature is exceeded by the passage of the current which opens the circuit and protects the treble. Positive Temperature Coefficient PTC devices or thermistors can be used to protect speakers.
Littelfuse PolySwitch and POLY-FUSE devices are Polymeric Positive Temperature Coefficient PPTC devices which offer a resettable overcurrent protection alternative thereby reducing warranty service and repair costs. They are not foolproof and will not protect against mechanical overload. Eminence sells D-fend boards to build into speakers but they are not cheap or widespread.
Low cost speaker protectionMore specifications ensure accurate choice for better protection. Positive Temperature Coefficient PTC devices or thermistors can be used to protect speakers against electrical current overload But not from low frequency input overload. Why protect the tweeter and midrange unit.
Although the protection circuit is fairly simple it forms an effective guard against overload of the input of amplifiers and loudspeakers. Stocking circuit breakers loudspeaker protection polyswitch protection tweeter protection lamps for crossovers. This circuit give both voltage protection and amp load protection by the resistor and thermistorbecause the mov will clamp the output and create a HUGE load to the amp so you need to put a series resistor to protect both the mov and the amp and i think a thermistor will be a nice addition to protect the over current that can be hurt the amp.
Or electronic circuits against overcurrentTypical applications are SMPSUPS supplies for LED lighting and electrical power meter. Overload protection for speakers. Application of polymer PTC fuse in audio system protection.
Sonofil TM Bass-reflex tubes Terminals Binding post Damping Carpet and Vinyl Laminate Protection grills Screws. They respond to inadmissibly high currents and also if a preset temperature limit is. But if sound companies renting their stuff out to meat headed DJs dont think this is worth it maybe it isnt.
Very common in the treble filters among others. A PTC consists of a piece of polymer materialloaded with conductive particles usually carbon black. Polyswitches will protect against electrical current overload and will protect speakers in most situations.
Flowserve supplies flow control technology that is critical to their customers operating efficiency and worker safety as they manage some of the highest pressure highest flow rate and most aggressive process streams in industry. Some speakers need more protection than others. In addition additional fuse boxes and wires increase the manufacturers cost.
Speaker stands Spikes Vinylflex. The speaker system is composed of a tweeter a midrange unit a bass unit and a frequency divider that distributes signals. Select the device based on its trip power.
The company Raychem makes a line of PTC devices named PolySwitch that are specifically intended for speaker protection. Ordinary fuses only play a one-time protective role in the horn which increases the repair rate of the product. PTC thermistors can effectively protect motors from such overcurrent.
RXE160 PTC Fuses - Speaker Protection CATNORN3466. Ideal for situations where frequent overcurrent conditions occur or constant uptime is required resettable PPTCs are. RXE160 PTC Fuses - Speaker Protection CATNORN3466.
This can result in thermal overstress to the coil. Other Fuses Holders. Positive temperature coefficient PTCthermistors also called resettable fuses or polymericpositive temperature coefficient devices PPTCs are anexcellent way of achieving this type of protection.
