Testing system for  the degree of protection of automotive headlights/lamps  against water spray or splash during operation - IP protection class IP X3 and X4 according  IEC 60529.

The system consists of:

Water spraying nozzles  swinging frame with tilting mechanism (motor + speed reducer + rotation control circuit:  angular amplitude, angular velocity, direction change )

• Water supply system, flow / pressure adjustable;

• Turntable - sample holder;

• Data acquisition system for parameters setting and test perform control, headlight / auto lamps power supply to execute a programmed cycle, data acquisition during test and generation of  test reports.

• Tilting frame geometry:
  • Full semicircle (180^o) ;
  • Diameter: 1800 mm (other diameters available between 1000 and 2000 mm) ;
  • Number of nozzles: 51 (depending on diameter) ;
• Angular oscillation range:  ± 170^o around the vertical position for IP X4, ± 60 ° around the vertical position for IP X3, (other ranges are possible); able to execute asymmetrical vertical oscillations;
• Maximum torque: 500 Nm, 1: 100 gear;
• Manually adjustable tilt angular velocity (max. speed  ± 60 ° / sec.) ;
• Brakes / accelerating at the end of the oscillation range to mitigate mechanical stresses in the frame to change the direction of motion;
• Water supply control system using solenoid valve, flowmeter, manual flow control valve and mechanical filter impurities; flow rate adjust between 30-300 l / h;
• Electronic control unit working voltage: 24 V DC;
• Motor drive  unit:
  • 3 phase Frequency converter 3 x 230 Vac;
  • Variable output frequency 0-120 Hz;
  • Speed: 900 ÷ 1400 rpm (f = 50 Hz); 1800 ÷ 2800 rpm (f = 120 Hz) ;
  • Power Supply / consumption 3x380 VAC / 50 Hz / max. 0.4 kW.
• Possibility of manual control of spray unit in the event of Data Acquisition System  failure .

• 6-channel independent adjustable voltage in the range  0 ÷ 30 Vcc / 0 ÷ 10 A, overcurrent and short circuit protection for each output channel;
• Voltage, current and power measurement for each channel, tabular or graphical display of values and information storage to generate reports;
• Programmable on/off sequences on each channel  according to test specification; programmable test duration;
• Test performing interruption (and measured data saving up to that point) in case of Power Failure, automatic test  resuming  when the power reestablishes;
• Visual Programming (without writing code) of test parameters;
• Water pressure and temperature  measuring and storing during the test; test chamber temperature measuring and storing; all values included in the test report;
• Generation, saving and printing of test reports in .pdf format (virtual printer) to be then stored electronically;
• Calibration of voltage and current measurement channels available;
