FAQ 

1.What are the overall length, width and depth dimensions of the VFD1850C43A-00 unit, as well as the net weight of the bare machine?

The

• Overall machine dimensions: (width 500 mm × height 1000 mm × depth 397 mm)
• Net weight of the bare machine: 134 kg

2.For VFD1850C43A-00, is there no need to reduce the load current when operating at an altitude of up to a certain height? And what is the attenuation ratio of the output current at altitudes exceeding this limit?

Supported. The

• Rated without reduction altitude limit: Within the 0 – 1000 meter range, it can operate at 100% rated current under full load.
• High altitude reduction ratio: After the altitude exceeds 1000 meters, for every 100 meters increase in altitude, the rated output current decreases by 1%.

3.Can the VFD1850C43A-00 cooling fan be disassembled and replaced independently? Does the driver have a function to warn of the fan’s operating duration?

The

• The cooling fan can be disassembled and replaced separately. After power is cut off, wait for the bus capacitor to fully discharge. Just remove the fixing screws of the fan cover to disassemble and install a single group of fans separately.
• It has a function to warn of the fan’s operating duration.

4.What are the fluctuation range of the three-phase input voltage and the compatible frequency range of the grid for VFD1850C43A-00?

The

• Three-phase input voltage fluctuation range: Rated 380~480VAC, allowable fluctuation range -15% to +10%
• Overall stable working voltage: 323～
• Compatible grid frequency range: 47Hz to 63Hz, compatible with standard 50Hz/60Hz industrial grid.
