Over Voltage Protection

Schematic Diagrams      Comments Off on Over Voltage Protection

Safety devices like fuses provide protection against excess current, but do nothing for transients and short duration spikes of high voltahe on the power supply lines.This circuit uses the “crowbar” method and provides fast protection against transient voltage spikes, transients that could cause damage to sensitive components. The thyristor will… Read more »

Delay to supply voltage for surge protector by scr

Schematic Diagrams      Comments Off on Delay to supply voltage for surge protector by scr

Power source that, when connected to an external circuit, and now will turn to a current surge.Power supply is a high voltage surges.External circuit therefore damage.Which can solve this problem with the delay to a power source.When supply switches.Delay circuit to work, the delay occurred during the current surge.Then connected… Read more »

Over voltage and low voltage protection circuit

Schematic Diagrams      Comments Off on Over voltage and low voltage protection circuit

This is an electrical circuit protection device sound disappeared, when too much voltage 220V, and protection, when pressure is too low with Using the relay cut off power when voltage problems. From the circuit when the voltage is 220 volts AC through a transformer T1. It serves to reduce the… Read more »
