Rated Duty Cycle; Hermal Protection - Panasonic YD-350GY4 Operating Instructions Manual

2.2 Rated duty cycle

■ YD-350GY4
● 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.
