Stanford Series Generator Accessories Automatic Voltage Regulator AVR

product presentation:

SX440 features: On the basis of SX460 to increase the parallel required DROOP adjustment and external TRIM adjustment (external power factor controller LSM206), is currently used the most practical parallel type AVRAVR is an automatic voltage regulator is an indispensable core part of modern generators. The main stator of the generator provides power to the exciter magnetic field through SX440, and the AVR is the control device that regulates the excitation current. The AVR feeds back the voltage signal of the stator winding, and adjusts the rectifier output power of the exciter by controlling the low power exciter magnetic field, so as to achieve the requirement of controlling the host magnetic field current. The SX440AVR ensures voltage adjustment by sensing a two-phase average voltage. In addition, it also monitors the engine speed. If it is lower than the pre-selected speed (Hz) setting, the output voltage will be reduced accordingly to prevent overexcited engine at low speed and reduce the impact during loading to reduce the burden on the engine. This is a half wave phase controlled voltage regulator for parallel units. The main features are as follows: Voltage adjustment rate is better than 1%, can be connected to the external potentiometer to fine tune the output voltage, low frequency protection (with the reduction of the frequency of excitation current also decreases) and LED indiCAT-parts-partsion frequency is too low state, simple external current transformer can automatically adjust the power factor, for different power levels of generators have different stable choice and 50/60HZ selection. Biggest feature: not only can the simple external current transformer power factor adjustment (in a small range), but also can connect the parallel unit special power factor controller LSM206, to achieve a large range of automatic adjustment, greatly improve the power loss, indirectly reduce fuel consumption.
