pre-drilled holes for K8060

This kit was developed as pre-module for a number of audio applications where the input signal is too weak. Applications as a microphone pre-amplifier or for level correction.

This small power supply provides a regulated voltage, adjustable between 1.5 and 35 volts at 1 Amp. With the LM317 regulator remarkably better ripple and regulation characteristics are given than w...

Miniature timer for all applications requiring a delay of up to 60 minutes. The control range may be adjusted. Specifications - power supply: 12VDC / 55mA - relay: 3A / 220V switchable - time inter...

Enter the world of amazing electronic sounds and noises. Create or imitate sirens of all kinds by adjusting 3 trimmers. Powerful sound with a 2W amplifier on the PCB - modulation speed: 0.5 - 5s - ...

Designed to control AC motors with carbon brushes (drilling machine, vacuum cleaner, saw, …). High torque, even at low r.p.m. May also be used for low voltage loads (24V). Supply and load circuit e...

Drive more safely in freezing weather. This kit uses a flashing LED to indicate a road temperature close to freezing point ; below that point the LED is on continuously. A reliable temperature sens...

This small amplifier is constructed around the TDA2003 IC, capable of delivering 4Wrms at 4 ohms. The IC is fully protected against overheating and short circuits. A conventional direct current is ...

This small amplifier is constructed with the TDA2616 IC, with a maximum supply capability of 2 x 15Wrms (4ohm) of 2 x 10Wrms (8ohm). The IC is thermally and short-circuit protected. Additional rect...

This stereo speaker protection prevents switch-on clicks and DC components on the output of the amplifier connected. - switch-delay: ± 6 seconds - DC protection: +1V/-1V - max. input voltage: 200Vp...

This code lock may be used to switch an alarm (e.g. car alarm K3504) on and off, or to open a door lock. An LED on the operating panel indicates the position of the 'lock'. The code is easy to defi...

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...

The K8055N interface board has 5 digital input channels and 8 digital output channels. In addition, there are two analogue inputs and two analogue outputs with 8 bit resolution. The number of input...

This relay card can be used in several ways : stand alone card, addressed by switches or open collector outputs or remote controlled through RS232. Since the card can be addressed using RS232 comma...

excellent value for money - fully discrete design using Epitaxial Darlington transistors - DC supply circuit on board with LED indication - ideal for active speaker system or subwoofer, guitar amp,...
