SCR DC CIRCUIT BREAKER EXPERIMENTER. MODEL IBL-PE-22

A circuit breaker by the very name it suggests that, it is a mechanism, by which the power circuit must be disabled / disconnected if the output exceeds beyond a set current range. This facilitates the saving of men and material from any possible destruction. In this trainer, the circuit breaker is essentially monitors the load current. The sensing circuit determines the maximum load current CUTOFF point, beyond which the circuit should not function. In order to demonstrate this principle, an SCR based SSR is used in this trainer. This trainer comes with load current limiting circuit.

This trainer consists of DC power source at 12VDC @ 1A as supply to the load circuit. Suitable current limiting circuit measures the load current. An Ammeter measures the load current. It is possible to preset the load current in the range of 100mA to 800mA at load circuit side. An SCR based switch is used to cutoff the load supply to the loading circuit, when the load current exceeds beyond set current limits. An external loading rheostat NOT more than 1A is required to load the circuit.

Specifications:

  • Load current limiting : between 100mA to 800mA
  • Analog Current meter : 1A DC FSD monitors load current.
  • Current limit : By preset potentiometer.

Note: An external loading rheostat NOT more than 1A is required
