CURRENT PROTECTION COMPONENT TEST
Current protection component includes Fuse, Circuit breakers and a new PTC Resettable fuse etc.., its function is when the
circuit current exceeds the design of the rated value, that is, if the load exceeds the design of the current capacity, the circuit
will be disconnected, in order to avoid overheating, even fire. Fuse is a one-time use of the protection components, Breaker
and PTC can be reused.
The current protection components of the protection current value and the protection reaction time has usually a product of
the relationship that is, the greater the current through the current protection component, the shorter the reaction time to
protect the circuit. This is similar to energy protection components.
Due to this feature, the AEL-5000 Series AC & DC electronic load, in particular for the verification of current protection
components, has developed a Fuse Test function to test and verify such protection element with an electronic load of rated
current and power. When Turbo mode is set to ON, the test current can be up to double the maximum current within 1 second of
test period. Take AEL-5004-350-37.5 as an example, the maximum test current can be doubled to 75A. That is, when the Turbo
mode of the AEL-5000 Series is ON, the test current value can reach to 2 units AEL-5000 Series ( normal mode ) within 1
