Product Description
The design of HW-ADV is based on electromechanical voltage regulation that is controlled by digital technology:the embedded DSP (Digital Signal Processor) permanently compares the output measured voltage value with the reference one. Should the output voltage deviates outside tolerances. the control system immediately reacts and drives the servo motor to adjust the position of the brushes up to a point where the variable transformer will correct the voltage through a buck-boost transformer connected in series:
Ensure assets continuity, even operated with the worst electrical network conditions:
Wide choice of input voltage ranges
Symmetrical or asymmetrical voltage ranges
Accept 100% unbalance load and 100% unbalance input voltage
Maintain performances, whatever the downstream distribution conditions:
+/-0.5% output voltage accuracy over the full input voltage range, from 0% to full load, irrespective of the power factor
Independent regulation on 3-phase products that enables the unit to operate with 100% unbalanced distribution
Reduce maintenance costs, thus optimizing OPEX:
Frictionless voltage adaptation by patent split current design instead of traditional brushes
Same control board on each version of the HW-ADV series to reduce storage costs of spare parts
Patent software control makes the brush avoid over temperature
