Frequently Asked Questions
What is the required voltage range for operation?
The voltage range is 10-45V DC.
How does fan cooling determine compressor stability?
Static cooling and oil cooling are typically sufficient, but a fan speed of 3.0 m/s is necessary depending on application designs.
What is the maximum allowable ambient temperature in the machine compartment?
The maximum permissible operating temperature for the machine compartment is 55°C.
How can I determine the correct motor fuse rating for a given voltage?
For 24V applications, the listed main switch current consumption must be divided by two to find the required fuse value.
