Tension Reducer (PRB) for 8-controls solenoid valves - 758 Series
PRB (Power Reduction Board) scheme, expressly developed for 758 Series, 8 control models, allows a significant reduction of the solenoid valve power consumption and optimises its use temperature even in particularly difficult use conditions, such as:
• use with non-stabilized tensions
• use in high temperature environments
• continuative use with 100% duty-cycle
PRB circuit is totally transparent to control driver of the valve and it intervenes in the case in which control times exceed 100 ms, by providing the coil with a resistance in series with consequent reduction of feeding tension. Considering the low value of the required tension to keep the valve open, the dissipation on the resistance results extremely reduced.
Marginal note:
PRB circuit limits solenoid valves maximum operative frequency to 20 Hz.
PRB circuit is not consistent with solenoid valves equipped with anti-disturbance diodes.
