A crowbar circuit is usually placed across the power supply’s output terminals, to protect the load against any overvoltage. It does this by shorting the terminals (placing a crowbar across) which deactivates the protection device. It may blow up the fuse, trip the circuit breaker or shut ...
A crowbar circuit provides one of the simplest, cheap and effective over-voltage protection methods. This is usually connected between the regulated output and the protected circuit or load. The series regulating transistor controls the output current and voltage while the crowbar consists protects the...
the thyristor turns off the power supply output to the ground and activates circuit breakers or fuses upstream from the power supply. This is called acrowbar effect
acrowbar circuitry is exercised by short-circuiting the output and by down ranging the instrument excessively. 撬杠电路行使通过短路产品和通过下来过份排列仪器。[translate] ais it use the recycle mattress or coir cup? 它是否是用途回收床垫或粗硬纤维杯子?[translate] ...
2.2.6. CROWBAR AND DISCHARGE CIRCUIT The crowbar is a safety feature designed to protect the excitation system and field winding from external surges, generator pole displacement, etc.
