STAMFORD SX421 VOLTAGE REGULATOR FOR STAMFORD GENERATORS STAMFORD E000-24210, 594-080 General Description / Specifications SX421 is a three phase sensed Automatic Voltage Regulator and forms part of the excitation system for a brush-less generator. In addition to regulating the generator voltage, the AVR circuitry includes a quantity of other useful features. Excitation power is derived straightforwardly from the generator terminals. Positive voltage build-up from residual levels is ensured by the use of proficient semiconductors in the power circuitry of the AVR. The AVR senses the voltage in the main generator winding and controls the power fed to the exciter stator and hence the main rotor to sustain the generator output voltage Within the particular limits, compensating for load, speed, temperature and power factor of the generator. SENSING INPUT > 190-264V ac max, 2 or 3 phase > 50-60 Hz nominal POWER INPUT > 190-264 Vac max, 3 phase only > 50-60 Hz nominal OUTPUT > Voltage max 90V dc at 207V ac input > Current continuous 4 A > Intermittent 6A for 10 secs. > Resistance 15 ohms minimum * other type will be available on special request This NEW product, , NO SECOND...! ! ! .............
