2.2 Rated duty cycle
■
YD-500GP5
●
The rated duty cycle is 60 %. This means that the machine can cut for a total of 6 minutes out of any 10 minutes at the
rated current, and then, during the remaining 4 minutes, the machine must be cooled down to prevent overheating.
●
Exceeding allowable duty cycle can cause the temperature rise higher than the maximum allowable temperature,
resulting in the performance degradation or damage.
●
The figure above shows the ideal value of cutting current and duty cycle. Please use the machine within the
corresponding duty cycle of cutting current.
2.3 Thermal protection
●
Cutting power source is equipped with a thermal switch at the radiator fin of IGBT to monitor the temperature.
●
When the abnormal temperature happens, the thermal switch takes action and cut off the output.
●
Please be sure not to use under the conditions listed here:
●
Over the rated output voltage.
●
The air inlet or outlet is blocked.
●
The ambient temperature is higher than 40°C.
●
The cooling fan stops.
