[Mike Worth] wanted the option to run his Microwave Oven Transformer welding rig at less that full power. After being inspired by some of the other MOT hacks we’ve featured he figured there must be a ...

The new Thomas & Betts Hi-Tech 38kV Trans-Guard OS Shorty Backup Current-Limiting Fuse provides risk reduction of disruptive transformer failure. Designed for use in 26.4 to 34.5kV distribution and ...

Figure-1 shows the schematic diagram of the device. P1 is used to connect the 220V-AC input and the ON/OFF switch to the circuit. C1 is used to reduce the AC voltage. The value of the C1 also ...

Current transformers can perform circuit control, measure current for power measurement and control, and perform roles for safety protection and current limiting. They can also cause circuit events to ...

TDK-EPC has extended its range of EPCOS inrush current limiters (ICL). The P11 series (B57211P*) covers a resistance range from 4 to 25 ohms (R25). These types are designed for currents from 2.5 to 5 ...

Here at Hackaday we really like to feature projects that push the limits of what’s possible, or ones that feature some new and exciting technology that nobody has ever seen before. So what’s so ...

The circuit was designed to create a DC power supply that will be rated with 13.8 V and 20 A while having a current limiter and short circuit protection. By producing 13.8 Volts at around 20 Amps, the ...

The portfolio of ac inrush current limiters from Camtec Power Supplies has been expanded to include the new ESB001 series. This series is currently the world’s smallest for its performance class, and ...
