Just add a suitable transformer to power your project - 1.2V to 30V adjustable output. • output current: 1A max. • max. dissipation: 15W (cooled) • max. input voltage: 40VDC

Can drive up to four 1W power LEDs or two 3W power LEDs. Highly efficient switching circuit. • 350mA or 700mA constant current source • input voltage: 6..12VAC/9-18VDC • power consumption: 650mA max.

>> K8042 HHH SYMMETRIC 1A POWER SUPPLY • positive and negative output adjustable between 1.2 and 24VDC • output current: up to 2 x 1A continuous (with suitable heatsink) • max. input voltage: 2 x 24VAC • very good line and load regulation • low ripple • short circuit protection • thermal protection • optional heatsink: HS4003 (for maximum 20W dissipation)

>> K7302 H LOW COST UNIVERSAL BATTERY CHARGER • charging current: 50mA, 100mA, 200mA, 300mA, 400mA (selectable) • supply voltage: from 6.5V to 21V (depending on used battery) • supply current: same as charging current • power supply polarity protected • LED function indication

 >> K2543 HH ELECTRONIC TRANSISTOR IGNITION FOR CARS Gives your car a better starting and smoother running, particularly at very high and very low RPM. Even the most sceptical one has to admit that the electronic ignition system has a great advantage over the conventional ignition system. Car constructors now mount such a new system on their most expensive models. Only for petrol/gasoline engines and for cars with negative ground. • for use with 6V and 12V systems • max. current: 4A • typical firing period: 2.000 µ second • connection speed: up to 500kHz

 >> K7102 HHH METAL DETECTOR To come up against an electric cable while drilling a hole in a wall can have catastrophic consequences. Likewise, drilling into gas, water pipes or central heating pipes can be extremely hazardous. With a handy metal detector it can now be determined beforehand whether there are metal objects to be found in a wall, ceiling or floor. An LED indicates if a metal object is in the vicinity. • metal detecting distance adjustable: up to 8cm (3.15") • power supply: 9V battery (not incl.) • LED indication • 12VDC-buzzer connection (buzzer not included) • dimensions: 56 x 64mm (2.2" x 2.5")




Add another screen to your computer that shows the information you want! Even if your main screen is off. • LED - Backlight (white) • LCD resolution: 128 x 64 pixels • USB powered • Max. power consumption: 35 mA

>> K8096 HHHHH 1 channel >> K8097 HHHHH 4 channels USB STEPPER MOTOR CARD

While the motor turns you can simultaneously check the status of the dry-inputs (ex. emergency stop signal, limit detection...). Use the switch inputs to test the motor. Can be used in every application where positioning is needed (for example, plotter, printer, valves, automations …). • power output: 750 mA continuous, (1 A peak) • wide range AC - power input: 5 ... 30 V • 5 dry-contact inputs for K8096 and 6 dry-contact inputs for K8097 • 1 logic open collector output • power supply: 10 ... 30 VAC
