a. If high output power is used continuously or with a high cycle, the equipment generates excess heat. The output power is
automatically decreased when necessary to prevent overheating. Typical operating times are shown in the chart with different output
powers and duty cycles @ 22°C and 35 °C (see chapter 3.2).
b. Limited output power is available as on order option.
