AVR regulation<\/h3>\n\n

AVR – Automatic Voltage Regulator.<\/strong> \nAutomatic regulation with a tolerance of +- 2%.\u00a0<\/span> \n \n\u00a0 \n \nIf it is an appliance that you know is sensitive to voltage fluctuations (e.g. sensitive medical devices, tools with electronic control of the input voltage), you must choose the type of output voltage regulation of the generator very carefully here. You will use a generator with an AVR. It is an electronic regulation of the output voltage, which ensures that the fluctuation of the output voltage will be within a tolerance of \u00b1 2% in the entire range (at constant load) up to the nominal power of the generator. (AVR is not necessary for PEGAS, PERUN or ALFIN welders with PFC – power factor correction, which are not susceptible to voltage fluctuations, but it is necessary to count on a power reserve of a power generator of at least 30%).<\/span><\/p>\n\n

CCL compound regulation<\/h3>\n\n

Compound CCL regulation<\/strong> If you need to “spin” an asynchronous motor on a circular saw, a paving cutter, or a compressor, i.e., a device with a difficult start-up, you definitely choose a power generator with a compound transformer. These motors do indeed have a “HARD START”, but the compound transformer ensures that the central unit is able to supply a large starting current, even at the expense of the voltage drop. A lower voltage will not harm the asynchronous motor in any way. Calculate that for your “one kilowatt” motor you need 2 – 4 times its rated power in the short term. Inverter welding machines PEGAS, PERUN or ALFIN with PFC – power factor correction – can be operated without problems on power plants with compound transformers.<\/span><\/p>\n\n

Capacitive CCL regulation<\/h3>\n\n

Capacitive CCL regulation.<\/strong> The last series of appliances are manual tools with commutator motors, for which the output voltage with capacitive regulation is sufficient. The power consumption of the appliance can be up to the maximum rated power of the power generator.<\/p>\n\n

AVR+CCL regulation combined<\/h3>\n\n

It is a combination of both controls, which uses the most advantageous properties of the two previous ones. When the engine is started, it behaves like a standard CCL, i.e. it does not limit the engine start-up, and output voltage fluctuations are solved as an AVR regulation, so it is within a tolerance of \u00b1 2% in the entire range (at constant load) up to the nominal power of the power generator.<\/p>\n\n

iGX engine designation<\/h3>\n\n

Designation of Honda engines that are equipped with an electronic speed controller. The latter can more accurately maintain a constant engine speed even with changing load. Another advantage is the automatic choke function, even when starting without a starter battery<\/p>\n\n

EFI (Electronic Fuel Injection)<\/h3>\n\n

Features using electronic fuel injection. The engine is controlled using an ECU control board and several sensors that evaluate the optimal amount of fuel depending on the load. EFI will increase fuel efficiency, reduce exhaust emissions and provide easier maintenance. All the good manufacturers already use it in their better and more powerful engines. The power generator maintains power and output parameters better.<\/p>\n\n
