Battery protection devices boost LiP and prismatic battery safety
Littelfuse Inc. had introduced the introduced MHP–TAC (Metal Hybrid PPTC – Thermal Activated Compact) Series Resettable Over-temperature Protection Devices, the latest addition to its line of battery min-breakers. These devices connect a PPTC (Polymeric Positive Temperature Coefficient) device in parallel with a bimetal protector (a resettable thermal cut-off device) to protect the high-capacity lithium-ion polymer […]
New e-commerce site offers current sense shunts and fuse block products
Riedon has announced the industry’s first e-commerce site dedicated to the rapid sourcing of current sense shunt and fuse block product lines. Shunts.com is designed to significantly simplify the identification and purchase of shunts and fuse blocks for use in a wide variety of commercial, industrial, aerospace, transportation, instrumentation, renewable energy and medical applications. Orders placed on […]
Ground fault sensor monitors 100-A circuits with large sensing window
NK Technologies released the AGT-FD Series, new ground fault sensors that detect faults to earth from 0 mA to 100 mA and produce an output signal of 0–10 VDC in proportion to the amount of current passing to ground. The output is equal to the RMS value of the earth leakage. The AGT’s sensing window is […]
IP67 splash-proof IEC plug contains its own circuit breaker
SCHURTER enhanced its IEC inlet and circuit breaker power entry module with IP Protection. The DG 11 IP67 splash-proof IEC plugoffers an IEC plug C14/C18 with integrated a device circuit breaker TA35 to meet the requirements of the variety of applications. The DG11 power entry module is IP 67 rated, which prevents ingress of dust […]
Reflowable thermal switch protects power semiconductors against thermal runaway
A particularly compact reflowable thermal switch is designed to provide thermal protection for power semiconductors such as MOSFETs, ICs, IGBTs, TRIACs, and SCRs. Due to their inherent self-reinforcing heat-producing behavior, these semiconductor devices can overheat and go into thermal runaway. The RTS is designed to protect against such overheating by reliably interrupting the circuit precisely […]
Six considerations for better circuit protection
In an electronic system where the power source can be connected the wrong way round, protection should be considered to prevent damage to the circuitry. Most electronic circuits don’t like the power supply being reversed. However, there are other eventualities you could protect your circuit or system from temperature, humidity, excess current or excess loading, […]
Basics of ground fault interrupters
Ground-fault circuit interrupters (GFCIs) are sometimes also called earth leakage or residual-current circuit breakers. They can sense leakage current to earth ground and interrupt the circuit automatically when leakage current exceeds a predetermined value. A typical way of detecting ground fault currents is through the use of a core-balance protection device. Here hot (sometimes called […]
Zero Surge ‘FF1 Series’ filters have branch circuit surge protection
Zero Surge Inc. “FF1 Series” surge suppression for commercial and industrial applications integrate a patented filter system unlike others to provide unprecedented protection for one or multiple branch circuits. Using Spectrum WVR® (Wide Voltage Range) filter technology, the surges sense and suppress power line surges whether the power is low at 85 V, high at […]
