Line Power Supply - Danfoss FC 103 Instruction Manual

Specifications
1)
For type of fuse, see chapter 8.8 Fuses and Circuit Breakers.
2)
American Wire Gauge.
3)
Measured using 16 ft [5 m] shielded motor cables at rated load and rated frequency.
4)
The typical power loss is at normal load conditions and expected to be within
conditions).
Values are based on a typical motor efficiency. Lower efficiency motors will also add to the power loss in the adjustable frequency drive and vice
versa.
If the switching frequency is raised from nominal, the power losses may rise significantly.
LCP and typical control card power consumption values are included. Further options and customer load may add up to 30 W to the losses.
(Though typically only 4 W extra for a fully loaded control card or options for slot A or slot B, each).
Although measurements are made with state-of-the-art equipment, some measurement inaccuracy must be allowed for (
5)
The three values for the max. cable cross-section are for single core, flexible wire and flexible wire with sleeve, respectively. Motor and line cable:
300 MCM/150 mm
6)
A2+A3 may be converted to IP21 using a conversion kit. See also Mechanical mounting and IP21/Type 1 Enclosure kit in the Design Guide.
7) B3+4 and C3+4 may be converted to IP21 using a conversion kit. See also Mechanical mounting and IP21/Type 1 Enclosure kit in the Design
Guide.

Supply voltage
AC line voltage low/line drop-out:
During low AC line voltage or a line drop-out, the adjustable frequency drive continues until the intermediate circuit voltage
drops below the minimum stop level, which corresponds typically to 15% below the adjustable frequency drive's lowest rated
supply voltage. Power-up and full torque cannot be expected at AC line voltage lower than 10% below the adjustable frequency
drive's lowest rated supply voltage.
