AMWEI PTC Thermistor for Lighting Time Delay and Switching Starting Application |
|
|
Lighting Switching PTC Thermistor Description Lighting Switching PTC Thermistor are used when a load in series with the PTC thermistor has to be switched off after a time delay and when switching occurs frequently. A typical application of switching PTC thermistor is the preheating of electrode in energy-saving lamps or fluorescent lamps. Switching PTC can also be used as a power resistor for loading a capacitor, for example in power supplies or in control units of production equipment. Lighting Switching PTC thermistor Application It's applicable to various types of fluorescent lamp, electronic ballast and electronic energy-saving lamp. The PTC can be connected across the lamp resonator without changing the circuits. It can change hard start of the ballast and electronic energy-saving lamp to preheated start and the preheating time of the filament can come up to 0.4-2 seconds, which will extend the service life of the fluorescent tube by over 4 times. |

AMWEI PTC Thermistor for Telecom Over-current Protection |
|
|
Telecom PTC Thermistor Description This series of ceramic PTC (positive temperature coefficient ) thermistors help provide protection against power cross, power induction surges and lighting surge defined in ITU, Telcordia, UL. Available in chip, radial-leaded coated and non-coated, SMD, twin vertical surface mount configuration. PTC thermistor overcurrent protector provides reversible, self-resetting protection against over-currents of telecommunication line protector units, improve the reliability of custom premises and network equipment. Ceramic PTC thermistors can be found providing re-settable line protection at the exchange, monitoring hot spots and protecting ringers, battery feeds, transformers and relay circuits. Also used extensively to protect the mobile phone's battery pack against overcharging in land-based and radio mobile communications. Advanced developments in telecom equipment in recent years have radically altered the protection requirements of both exchange and subscriber equipment. The PTC thermistor must protect the telephone line circuit against overcurrent, which may be caused by the following examples: Surges due to lighting strikes on or near to the line plant. Short-term induction of alternating voltage from adjactent power lines or railway systems, usually caused when these lines or systems develop faults Direct contact between telephone lines and power lines. To provide good protection under such conditions, a PTC thermistor is connected in series with each line, usually as secondary protection; However, even with primary line protection (usually a gas discharge tube), the PTC thermistor must fulfill severe requirements. Surge pulses of upto 2KV can occur and in order to withstand short term power induction, the PTC thermistor must withstand high voltages. If the line has primary protection, a 220V to 300V PTC thermistor is adequate. Without primary protection, 600V PTC device is necessary. We can manufacture a series of PTC thermistor fulfilling both requirements. Typical Application of PTC Thermistor in Telecommunication Protection Central Office Switching Equipment (C.O): analog and digital line cards, POTS, T1/E1 equipment, xDSL modems and splitters, multiplexers, CSU/DSU, servers. Primary Protection Modules: MDF (main distribution frame) modules, network interface devices (NIC). Custom Premises Equipment, also known as subscriber terminal equipment (T.E.), IT equipment: Modem, phone sets, fax machines, phone wall outlet (plugs), alarm systems, answering machine, PBX systems, ADSL Splitters, internet appliance, POS terminals. Access Network hardware, LAN WAN equipment, Powered Ethernet systems, VoIP (voice over IP equipment), integrated voice data (IVD), Set-top box (S.B), etc. Telecom PTC Thermistor Features Compliant with ITU-T K20 K21 K45 --Basic level lightning surges (10/700μs) --Basic level power Induction (600V,1A,0.2S) --Power contact criteria A/B (230V,15min.)

Round leadless disk thermistor availble for combined usage of PTC and primary protection, e.g gas arrestor. Matching available with narrow resistance tolerance. Tight resistance tolerance maintained after switching. Negligible resistance drift after soldering or switching. |

AMWEI Inrush Current Limiting Power NTC Thermistors |
|
|
Power NTC thermistor can be a cost effective device to limit the amount of inrush current in a switching power supply or other devices when the power is first turned on. Power NTC thermistor limits surge current by functioning as a power resistor which drops from a high cold resistance to a low hot resistance when heated by the current flowing through it. Inrush-current limiters power NTC thermistor protect circuits from undesirably high currents, suppressing high inrush current surges, while its resistance remains negligible low during continuous operation. Thanks to their low resistance in the operating state, Power thermistor have a considerably lower power dissipation than the fixed resistors frequently used for this application. Inrush Current Limiting Power NTC Thermistor Application limiting surge current, suitable for the protection of switch mode power supply, UPS power, transformers, motors, various electric heating utensil, energy saving lights, ballast, various power circuit, amplifiers, colored displayer, monitors, color TV, filament protection, etc. Power thermistor components can also be used for the soft starting of motors, for example in vacuum cleaners with continuous currents of up to 20 A. Inrush Current Limiting Power NTC Thermistor Advantages: Low cost solid state device for inrush current supression. Minimise line current distortion and radio noise. Protect switches, rectifier diodes and smoothing capacitors against premature failures. Prevent fuse from blowing in error. Inrush Current Limiting Power NTC Thermistor Features: Resin coated disk thermistor with uninsulated lead-wires. Suitable for both AC and DC circuits up to a voltage of 265 V(rms). Wide range of resistance, current and dimension. Excellent mechanical strength. Suitable for PCB mounting. |
