Advantage of apply MF73 NTC THERMISTOR

 

Best choice for limiting inrush current

Leading Technology Perfect Function Originate in domestic

Max steady state current : 120A

 

Inrush current is the momentary surge of current created when power is turned on to motors,transformers,power suppliers and heating elements. The more power required by industrial equipment,the larger the inrush current. It can effectively quench the inrush current by means of in series with power NTC thermistor in return circuit of power supply. The thermistor’s resistance decreases dramatically following the inrush,allowing the steady state curent to flow with very little resistance.This effect provides inrush current protection, yet allows efficiency during normal operation.The power NTC Thermistor produced by Guangdong Uchi Technology Co.,Ltd. with large scale,especially MF73T,MF73,MF74,MF75 serial products with big size,which can be applied in such inrush protection with industrial level as industrial robots and automation.

 

 

Characteristics

 

Reliable configuration and convenient installation
Strongest capability of surge current protection and energy absorption
Max. Steady state operating current
Long life and high reliability

 

 

Recommended Application

 

All kinds of power supply,UPS power supply,switching power supply

EV charger,charging pile

Motor dirver,superpower server motor driver,logic controller

High power plasma electric welder,cutting machine,super power lighting lamp

Nuclear magnetic resonance equipment,super power audio power amplifier,high power circle transformer

The solar panel arrays with high capacity power inverter

Then industrial robot drived by high voltage power supply,intelligent electric cabinet with lower voltage
