LOW FREQUENCY GENERATOR
Generator LFG-50 is used as a signal source in a cable tracing and fault location set for the following applications:
LFG-50 stands out from other portable low frequency generators with its unusually high output power (up to 50 VA). High power output significantly extends the useful signal range and ensures accurate location even under such adverse factors as large burial depth of an object, wet soil, external inductance, etc.
The generator features four sets of frequencies each containing three different frequencies. Frequencies may be customized on request. The wide frequency selection allows for almost any low frequency signal receiver to be used in conjunction with the generator.
The output impedance of the generator is automatically matched to the load, which ensures maximum signal power in a wide resistance range (0.5 ... 1000 Ω). This function makes LFG-50 suitable for use in adverse location conditions as well as enables effective tracing of very long cables.
The generator can output complex signals formed by adding a number of different frequencies together.
Signals formed with adding two-frequencies allow a compatible signal receiver to determining a burial depth of an object during tracing.
Three-frequency signals allow to fine tune the receiver right during the tracing process.
Signals generation in pulse mode simplifies location at high levels of background noise.
Pulse mode can also significantly extend the operating time of the generator when powered from a built-in battery.
The generator is equipped with a monochrome OLED display which provide clear readings even in bright sunlight.
The display conveniently and clearly indicates the operating mode, output power, current and voltage levels, built-in battery charge and other operating parameters.
Along with a direct connection, it is possible to connect the generator to an object using inductive coupling (by means of a signal clamp or a built-in transmission antenna). Inductive coupling is used when either there is no access to the conductive parts of the object or it is energized.
Portable generator LFG-50 weighs only 8 kg and is enclosed in a compact and shock-resistant case protecting it against mechanical damage, dust and moisture. The generator is equipped with a built-in rechargeable frost-resistant lithium-iron-phosphate (LiFePO4) battery and an integrated control panel LED illumination. The ability to power the generator from the battery, mains or an external 12-volt DC source makes LFG-50 well suited for field operation.
