random generator
Founded in 1995, China Dongda Power Industry Co., Ltd. is one of the few random generator manufacturer and distributor in China that has patents on the generator, motor, power supply, engine, alternator, diesel and gearmotor design, supply and sale. Our custom random generators has obtained the certifications of ISO9001-2000, GS/TUV, CE, VL, EPA, QHS, SON, CAP and SRS and we have won EPA 2005 Motor Year Certification. Our 30 QC staff carefully performs inspections at every stage of production, from the time we receive raw materials to packaging. Noise, power, and stability are tested to ensure that our engines can endure 580 hours of constant use. We also can design and deliver OEM/ODM samples in one month.

random generator

Prh-ZG2 works as an independent unit for controlling personnel staff. There is already integrated a power supply for the connection to 230Vac, including a switch within the mains cable. Furthermore you can see on the picture above a high-quality silver coloured pushbutton to order the calculated random decision '"red'"or "green", which means "control" or "pass". The Housing can be mounted on a wall or table with only two screws. Dimensions: 13cm x 9cm, height: circa 5cm. 230Vac / 3 VA , mains cable / mains switch , internal fuse. High grade pushbutton with superior tactile feel to order the calculated random decision '"red'"or "green", which means "control" or "pass". The setting is done normally only one time with srewing two internal binary coded decimal switches. Following there are for example some rates which are correspond to the average number of controlled passes (red): 0 0 = 0,5% = average every twohundredths person is to be controlled (red). 0 1 = 1% average every hundredths person is to be controlled (red). 5 0 = 50% average every second person is to be controlled (red).

This circuit can be used as a guessing number game or the lower or higher winning number or other applications of your choice. An LED is connected to each output as shown with a current limiting resistor (1K) connected to ground. The Fast clock circuit is used connected in series with a simple push or toggle switch connected to pin 14 of the IC as shown . The oscillator frequency can be adjusted with RV1 . Another additional ON/OFF switch should be used for the power supply to pin 16 . When the power is turned on the oscillator is activated and when the push button is depressed the LEDs will start flashing in sequence at the rate set by the oscillating Fast Clock Trigger and as the button is released only one LED will remain lit at random. Each LED could be identified as a labeled number or letter hidden behind a small amber window panel .
