PS20 International HI-LO Control Unit 12v (951079)
Electrical control for pneumatic sirens.
The PS20 is an electrical system consisting of a control unit that controls two magnetic valves (normally closed).
Air horns can be connected to the valves. They are opened and closed according to the programming (depending on the country) of the control unit.
This system is extremely suitable for vehicles with air on board.
Because the air pressure comes from the on-board air system; a separate compressor is no longer necessary.
This improves the reliability of the sirens and the maximum 'on' position of the system compared to a separate compressor.
The PS20 system has been tested against electromagnetic interference and is manufactured and developed in accordance with: CEE2009/19 and ECE Reg. 10.
This control can be used in combination with several types of FIAMM air horn sets.
Please note: You will need an On-Board Air System for this product.
