Main supply requirements
The SP-700 hydraulic unit has a single phase motor with a power of 1.8 kW. Due to the applications of this machine, usually in the field, with no connection to the main supply, it generally requires the use of autonomous generators.
Because of the peak in power consumption that occurs when starting up of the motor, a minimum power of 16 kVA is required. 20-30 kVA generators, that provide a more stable service, are recommended for these applications.
Bear in mind that the length of cable used to connect the unit is a critical factor in applications of the wind power sector, as it normally exceeds 80 meters from the power supply to the Unit. The voltage drop must be reduced as much as possible, as it can cause malfunction of the hydraulic unit. Check the following table for advice on the section of power cable recommended for keeping the potential drop below 5%.
Cable length (m) | Normalized section (mm) 230 V / 115 V |
|---|---|
15 | 1,5 / 4 |
25 | 1,5 / 6 |
50 | 2,5 / 10 |
75 | 4 / 16 |
100 | 6 / 25 |
125 | 6 / 25 |
