The HVEVSSR board is designed to resolve a number of problems bound to the reaction speed of electro-mechanical actuators powered at 24Vdc (solenoid valves, electric brakes, solenoids, etc.).
The HVEVSSR board is used to drastically reduce the reaction time (activation) of the actuators connected to it, thus increasing working speeds. The activation time is cut by instantly over-boosting the voltage, which magnetizes the actuator quicker than with a nominal voltage of 24Vdc. |
Unlike other systems, the HVEVSSR board offers many advantages:
It is easy to install on new and existent systems:
-
The HVEVSSR board is installed along the cables that connect the actuator to the control system (PLC, cam-controller etc.) without any precautions in particular.
-
All it needs to be able to work is a power supply voltage of 24Vdc, thanks to the built-in converter that generates the over-boost voltage.
-
It can be interfaced with control systems in PNP logic or in NPN logic.
It safeguards the actuators: the over-boost pulse has a duration of just a few milliseconds, consequently there is no overheating of the coils controlled, which could causes damages, typical in systems in which the actuators are powered at voltages higher than the nominal voltage.
