REPRESENTATION VOLTAGE REGULATOR TYPE S130 Nominal 100÷490 V tension 50/60 Hz Excitation { Ie = 10 A Ve = 100 V TECHNICAL DESCRIPTION After over twenty years’ experience in the alternators field, BELTRAME c.s.e. has produced a new kind of AVR called S130, which ensures the highest degree of performance for brush-less and old fashion generators, suitable for any use condition. The S130 AVR is the result of the most sophisticated technology offered by electronics. It makes possible the feeding of stator exciting units for 10 A, at values of nominal voltage up to 100 Volts, and it can therefore be used on most machines available on the market. It guarantees the optimum performance of alternators, be they charged, uncharged or in transition phase, in particular during the breakaway of asynchronous motors. It ensures safe protection against persistent over voltage and over load perturbation. All the components are resin-finished in order to warrant long lasting reliability in any environment and avoid damage caused by vibrations. The S 130 is cased in a strong plastic box. It is furthermore supplied with insulated electric clamps connection and internal fuse block, complete with an high-speed fuse as protection against short circuits. Characteristics: - Nominal input voltage 100÷490 V - 50/60 Hz. - Precision : in steady condition ± 1%. - Nominal continuous current 10 A. - Nominal output voltage 100 Vdc. - Operative temperature range –20 ÷ +65 C°. Complete with: - Voltage adjustment trimmer. - Stability control trimmer. - Under frequency protection trimmer. - Protection against maximum excitation in under frequency condition ( between 40÷50 or 50÷60 HZ ), when diesel or hydroelectric plants are set to self heating from the start. - Over voltage protection ( internally calibrated at ± 25). - Self-excitation at minimum 3,5 Volts. - Jumper 1 for 1000 - 1 ( ±10% ) Watt remote control potentiometer. - 50/60 Hz jumper. - Red jumper 2 for 115 V work. - Jumper 3 for 50/60 Hz work. - Dimensions: 137 mm W, 108 mm H, 48 mm D; weight g 820. - The 10 A version also has an electro-magnetic compatibility filter (according to EMI norm). PERFORMANCE The new S130 AVR is suitable for every type of alternator, and it ensures a high current 10 A in a very low dimension. It is complete with over-voltage protection (displayed by a yellow led), and under frequency protection (displayed by a red led). During the first step the voltage increases proportionally with the frequency, to get the under frequency set normal ( the starting point of the low-turns protection trimmer is 20% less of frequency normal value, and this function can be jumped between 50/60 Hz); and from this point on, also the voltage goes immediately to the nominal value. If different voltage or frequency is needed , BELTRAME c.s.e can supply the regulator according to the feeding value desired by the customer.

approaches the nominal value only when the frequency equals the trimmer set value (Hz), and then remains steady onto the nominal value. In this way, regulation is available as a compound with all advantages and precision of electronic regulators. This system moreover allows to charge heavy loads on the main without hampering diesel engine efficiency, both on turbo compressed or old fashion, and hydroelectric stations. INSTALLATION The regulator must be installed inside the machine or inside the control panel in order to be protected against accidental contacts. It is recommendable to install...
