This tester can be used to test light emitting diodes for all kinds of function, brightness, colour and polarity. The LEDs can optionally be tested with the following currents: 1 mA, 2.5 mA, 5 mA, 10 mA, 20 mA and 50 mA. The test contact can accommodate...
Switches off automatically when turning on a machine, light, etc. another load. You can 1-phase or 3-phase (phase) machines can be monitored (a phase scanned). The output side can 1-phase devices (e.g., vacuum cleaner) is automatically switched on (or...
Switches on other devices with the built-in relay contact after pushing the button and automatically switches them off again after a set time. The time can be stopped any point by pressing the second button. Two push buttons are required for use.
Timer with adjustable times between 1 second and 2047 seconds or 1 minute and 2047 minutes. After pressing the button, the timer switches on and off again after the set time. A second button can be used to stop the time sequence at any time. External...
Flasher for bulbs, with adjustable flash sequence. Ideal for advertisements, model lighthouses, party lighting and such.
This electronic dimmer switch switches on the lamps or other consumers automatically by means of an in-built relay when twilight falls and switches them again off upon daybreak. The module can also work in reverse i.e. on upon daybreak e.g. for advertising...
This LED with soldered constant current electronics may be connected at any voltage between 4–30 V/DC. The LED shines with almost constant brightness and has a consumption of ca.15 mA. An additional protective resistor is not required. The supplied...
When the fully insulated sensor plate gets wet (e.g. raindrops), a relay switches on. Unlike rain detectors with a metal sensor, this sensor works capacitive. In other words, it switches even when touched with distiled water (in completely clean rain)....
Kemo's M152 module combines a liquid sensing plate and 12V normally open contact relay to produce a switching operation based on an input of rainfall or snowfall. The relay is activated when rain is detected on the sensor plate and de-activated when water...
When the 2 sensor connections come into contact with water, a relay is switched on. Thus sirens or pumps, etc. can be switched. Feature: The water sensors are charged with an extremely low voltage in order to prevent the otherwise usual oxidisation through...
The Kemo M167N water level meter indicates on a10-level LED display, the water level in any water tank where it is not immediately possible to see the water level. This could be a garden water butt or a water tank on a caravan or boat. The module has...
Adjustable electronic temperature switch. The sensor (dia. 5mm) included can be connected to the control electronics using a cable of up to 1m in length.
Power controller for regulating DC loads such as from DC motors, light bulbs, heaters, LEDs with series resistors etc. The electric motors run well even with slow speed by means of used PWM pulse width controller.
This watering regulator measures the floor moisture and switches-on during drying e.g. a magnet ventile for water supply. The switching wave is set without stages. The measuring button of watering regulator is grounded deep in earth, where the measurement...
Power controller for regulating DC loads (DC motors, light bulbs, heaters, LEDS with series resistors etc.) by means of the used PWM (Pulse Width) control electric motors run well even at low speeds. Switching frequency: approx. 400 Hz (for engines, a...
