The core business of Kwant Controls is the design and manufacturing of various types of control units for the electrical remote control of practically all kinds of propulsion and steering devices, such as: traditional main engine/clutch/CPP-FPP shaft lines, tunnel thrusters, azimuthal thrusters, rudders and water jets.

Electronic dimmers
The Kwant Controls electronic dimmers of the ED-series yield an output voltage almost independent from the load current. This is a great advantage compared to the traditional solution using a power potentiometer.
They have two galvanically isolated circuits that are suitable for systems supplied by 24VDC and are each protected by an internal fuse.
Specs
The dimmer circuit is wired in series with the lamps and acts as a controllable power resistor. Each dimmer circuit has a pre-set potentiometer for adjusting the minimum brightness level of the lamps. If the dimmer circuit is placed in the positive supply lead of the lamps, it will source the lamp current. This is referred to as a P-type circuit. If the dimmer circuit is placed in the negative (minus) supply lead of the lamps, it will sink the lamp current. This is referred to as an M-type circuit.
Options
The electronic dimmer is available in three different executions:
- Execution 1: ED-MM = both circuits are of the M-type;
- Execution 2: ED-PP = both circuits are of the P-type;
- Execution 3: ED-MP = first circuit is of the M-type, second circuit is of the P-type;
- Execution 4: QED-MMMM = all four circuits are of the M-type;
- Execution 5: QED-PPPP = all four circuits are of the P-type;
If more than two groups of lamps have to be dimmed, a central multi-section potentiometer is used, available in 4, 6 or 10 gangs, each gang serving 1 dimmer circuit. Each dimmer power module is now supplied with a pluggable terminal block instead of the dual section potentiometer. The suffix ‘S’ (for Separate) is added to the type ID of the dimmer module (for example: ED-MM becomes ED-MMS).

Portable Wireless Control – Spectrum 3
The wireless portable remote control system is a smart and convenient alternative for fixed additional control stands, thus replacing e.g. bridge wing or fly bridge consoles. Saving considerably on building costs & mounting space. It comes with a back-up cable of 20m length that can be simply plugged in on transmitter- and receiver sides, as alternative forthe wireless transmission .
The system is suitable for:

- Propulsion control: Engine RPM, Propeller pitch.
- Steering control: Rudders, Azimuthal thrusters.
- Thruster control: Tunnel thruster RPM, retractable.
- Joystick operation.
CAN RC transmitter module
The CAN RC Transmitter Module reads CAN lever information (e.g. speed or azimuth) on the CANbus and converts this information to current level settings of the 2 DAC outputs.
The device offers flexibility of application with 4 predefined modes of operation for speed and 1 mode of operation for azimuth. All modes have configurable parameters that define the transfer functions for speed and azimuth. The device also allows for configuration via the CANbus in order to get more complex configuration of up to 12 points.

R/I converters
These DIN rail mounted electronic modules have been designed to convert the position of a remote control (RC) potentiometer into industry standard 4-20mA current signals. The RC potentiometers are an integrated part of all Kwant Controls control units.
