Definitions:

Ambient conditions for power ratings: Temperature 25°C, altitude 1000 m above sea level, relative humidity 30%.

Standby power (LTP): Emergency power. Maximum available power for operation with variable loads, limited to 500 hours per year. Overload is not permitted.

Prime Power (PRP): Prime power with variable loads. Maximum available power for operation with variable loads for an unlimited number of hours per year. The average power during a 24-hour period must not exceed 70% of the stated value.

Continuous power (COP): Continuous power with constant load. Maximum available power for operation with constant load for an unlimited number of hours per year.

Note: The data is taken from the original technical datasheet. Displayed values are nominal values, may change without prior notice and may vary by up to ±5%.

Verified technical answer

GE 20 PSX at a glance

GE 20 PSX is a three-phase benzin portable generator with 20 kVA / 16 kW PRP and 22 kVA / 17.6 kW LTP. The values below are taken from the assigned, field-audited manufacturer datasheet.

PRP output20 kVA / 16 kW
LTP output22 kVA / 17.6 kW
Phase / voltage3-phase / 400/230 V
FuelBenzin
EnginePERKINS - 404A-22G1
Tank / runtime60 lt. / 21.5 h

How should the output be interpreted?

PRP and LTP describe different rated operating conditions. The connected loads, starting currents and operating duration still need to be checked.

What confirms these values?

The visible values and structured data use the same field-audited manufacturer datasheet.
