Application

Low-frequency generator LFG-50, when operated in conjunction with a receiver, can be used for locating as well as tracing underground metal communications, such as any cables with metal cores as well as metal pipes. In addition, it provides operator with a quick detection of short circuits on cables as well as with an identification of a cable in a bunch.

Description

LFG-50 is a 50 W low-frequency generator with ability to inject a signal of three frequencies via direct connection to an object or via internal transmission loop antenna, which is built-in a cover lid. Basic frequencies are 491, 982 and 8440 Hz. There are options of using a singlefrequency
or multi-frequency signals at the output. The power of LFG-50 output signal can be adjusted up to 50 W with 2.5 W steps. This signal can be transmitted constantly or broken into separate blocks of 50 % duty cycle with 1 s repetition rate. A load matching is made automatically. Main parameters, such as output power, load impedance, selected frequency are shown on OLED display. If a load is higher than 1000 Ω LFG-50 automatically switches into output voltage setting mode. The output overload protection will trip, when operating on short-circuit loops (lower than 0.5 Ω).
