purpose

Continuously work S1 and continue working S3, and the ambient temperature of chicken feathers reaches+50 ℃.

The rated current in the table refers to the line terminal current during rated operation, but if the power supply is at a non rated value, it will inevitably cause a corresponding change in the rated current. Environmental temperature: -20 ℃~+50 ℃, hydraulic oil: DB-25 (SY1351-77) When it is below -20 ℃, YH-10 hydraulic oil can be used without a heater. When using DB-25 hydraulic equipment, a heater must be installed. The travel time is measured at an ambient temperature of 20 ℃.
