overloads on 5 kVA Comet S11 or S31

For a major temporary overload (greater than 1.5In):

The load is transferred to AC input power via the "static bypass" 3 for 5 seconds. After that time, it is transferred back to the inverter.

If the overload persists, this sequence will be repeated 3 times in all before the inverter is shut down and the supply of power to the load interrupted.

For a minor overload:

Minor overloads can be supplied by the inverter for a duration defined in figure 21 for an ambient temperature of less than 30°C. Above this temperature, a derating coefficient k must be applied to the rated current and therefore to the overload curve in figure 21:

■from 30°C to 35°C: k = 0.9,

■from 35°C to 40°C: k = 0.85,

■above 40°C: k = 0.8.

Example: an overload current I can be supplied by the inverter for 1 minute under the following conditions:

■1.1 In < I < 1.3 In for an ambient temperature of 25°C,

■1.1 x 0.9In < I < 1.3 x 0.9In for an ambient temperature of 32°C,

■1.1 x 0.85In < I < 1.3 x 0.85In for an ambient temperature of 37°C,

■1.1 x 0.8In < I < 1.3 x 0.8In for an ambient temperature of 42°C.

When an overload occurs:

■the buzzer 17 sounds,

■the orange "fault" light 19 goes on,

■ the inverter 7 shuts down at the end of its corresponding overload time,

■the load is supplied by AC input power via the "static bypass" 3 ,

■the green "load protected" light 21 goes off,

■the red "load not protected" light 18 goes on.

The load is supplied via the "static bypass" 3 for 5 seconds, after which it is transferred back to the inverter. If the overload persists, the inverter shuts down and the supply of power to the load is interrupted.
