Velleman Kits & Projects

If, like most of us, you do not have infrared eyesight, then at times you have probably found yourself fumbling for the ignition switch or seat belt in the dark. For people like you we have developed this solution. With extra push button and battery protection.

The alarm detects sudden voltage drops of the battery when the interior, trunk, or hood lights are switched on. To ensure correct operation, a number of control indications have been included, such as : flashing LED to indicate that the alarm is in standby mode after a set time (after you have left the car). Pre-alarm (built-in buzzer) to indicate that the alarm is activated, so that you will not forget to switch it off. The alarm is easy to switch on and off, either automatically or by means of the ignition switch or a remote control unit, such as the K8059/K8057 or MK161/MK162

This head light indicator may be set for one or two functions. To indicate that the headlights (or the sidelights) should be switched off after switching off the ignition contact (battery protection). Or to indicate that the head lights should be on once ignition contact is switched on (obligatory in some countries).

Universal, robust and compact are the key words that describe this amplifier. A stereo or a mono amplifier, with three input sensitivity settings. Overload and short-circuit protection, protection against incorrect power supply polarity and thermal protection. Speaker transient suppression.

A dedicated power supply board, designed for use with K4004B 200w Mono/Stereo power amplifier. Fitted with two reservoir capacitors (10000µf 50V), protection fuses and LED indicators. It can be used for any split rail power supply application.

Heatsink and transformer are included, ideally suited for installation into active speaker systems.

For most of us a high power valve amplifier is unaffordable. This kit changes that, so that now everybody can enjoy that sublime "valve sound". The sound of valves cannot be surpassed, neither by transistors nor FETs. In the development process, special attention was given to the housing so that the expensive valves are displayed in a visually attractive manner. The most vulnerable point of a valve amplifier are the output transformers; that's why we use ultra-linear and overrated output transformers (toroidal) to guarantee a rich bass response. To extend the life of the precious valves, the amplifier has a switch-on delay so that the high voltage is switched on when the valves are warmed up.
