An overcurrent detection voltage accuracy of ±1mV, the industry’s high-accuracy top class (The S-82A2A/B Series) Charge-discharge control through external signal input pin (S-82A2A and S-82B2A ...

The fuses meet UL 248-14 standards for long-term reliability and are suitable for use in secondary overcurrent protection. Application examples include secondary overcurrent protection DC and AC, ...

This circuit provides latching and high-speed overcurrent protection for power-factor corrected (PFC) boost converters operating at dc voltages to 380 V. Overcurrent damage of PFC front-end boost ...

During the positive cycle of the ac source, components R 1 , IC 1 , R 5 , C 1 , Q 1 ,D 1 , and C 3 work to detect an overcurrent (Figure 1 ). If the load produces an overcurrent, the voltage drop at ...

From no power to intermittent faults and hidden power quality culprits, learn how to quickly identify and fix the three most ...

The inverters were returned to our factory for repairs. One failure mode stood out and it accounted for 16 % of all repairs. The part that failed the most is a small signal transistor—part of the ...

Protecting these interfaces from overcurrent and overtemperature damage is frequently accomplished with resettable polymeric positive temperature coefficient (PPTC) ­devices. Protection systems Figure ...

Basler Electric inverse time overcurrent relays provide TCCs that closely emulate most of the common e-m induction disk relays that were manufactured in North America. To further improve proper relay ...

Group motor protection as described in NFPA 70, the U. S. National Electrical Code (NEC) Article 430.53 lets two or more motors be protected by the same overcurrent device as long as the ...

It’s available now on the S&C website. The IntelliRupter PulseCloser application has been expanded to include a sensitive earth fault time-overcurrent protection element. Users can now plot up to 25 ...
