Overview and Features

2

The Senser Xtreme R.2 is the complement to our proven Senser V2. It is a very powerful boost

constant current source that sets new standards. The (input) current can be up to 8 amps, so you can

already operate with very low input voltage, a large number of LED's with high currents. To be as

flexible as possible in your applications, many different output currents are set by solderbridges but

other currents through add / change the measuring resistors possible. The possibilities are endless,

please refer to our connection examples.

The Senser Xtreme has an external input which allows dimming by pulse width modulation. Either

you use this input for our final dimmer modules or your own development.

PCB layout / installation

Layout:

Connecting:

In principle, the following procedure is recommended:

Connect the LEDs, multiple LED's are connected in series or parallel *.

Pay attention to the input side on sufficiently thick cable. The current can be up to 8A!

Maybe you need to cool the driver, attach him if necessarily with an electrically insulating

material such as Thermal pad on a metal surface / heat sink.

1) Close the desired solderbridge(s) to set the output current. (The set current is derived from

the sum of all enclosed solder bridges)

2) Connect the power supply.

It is important to ensure that the input voltage <= Total-Led voltage. (Boost-principle).

If not the LED(s) get to much voltage and can damage!

3) Turn on the power supply

* For parallel-connected LEDs the voltage spread corresponding to the number of strands.

You have for example the solderbridge to 700mA and two LEDs connected in parallel, although the

voltage distributed 50/50%, but by the fluctuations of a typical diode, the LED current is distributed

in such two parallel lines is not exactly 50/50%.

If in a parallel connection one strand lose, the current is distributed to the remaining (n) Led strands.

Note: The module can be very hot during operation, check the temperatures in

continuous use before you install it! Make sure in your application on any adjacent

batteries!

Dimming with PWM:

The Led Senser Xtreme has an external input on what you can dim with a pulse width modulation

signal.

To the PWM-pad, a PWM signal with a recommended frequency of about 200Hz-10000Hz can be

connected. The duty cycle of the signal determines the brightness.

Turning on-off with DC:

If there is no voltage (GND) on the PWM pad, the driver switches off.

Explanation of the table "Leds, voltages, currents"

Here are some results of tests with different currents, input voltages and series-connected LEDs.

Please note that these are approximate and may vary from Led to Led. An attempt was made in the

measurement to determine very precisely what the minimum required voltage whatever number of

LEDs. The table is based on high white LEDs in other colors, these values can vary considerably. It is

important to ensure that the input current is no more than 7 amps.

Each row of the table gives two values:

1. The minimum input voltage for a given number of LEDs

2. The maximum input voltage for a given number of LEDs. (Value in parentheses)

(Values between themselves must be tested or calculated)

Here's an example with 12 LEDs in series at 1000mA. The max. Input voltage is 30V, the minimum can

be as 6.5V. 6.5V with 12 Leds can thus be operated.

Integrated temperature sensor:

The integrated temperature sensor starts at around 75 degrees Celsius to decrease the output

current linearly. If the temperature decreases, the output current rises again.

Important NOTE:

If the driver is operated at voltages below 6.5V, make sure that the input current does not rise above

5A. If battery supply is used, it must switch off at the latest at 6V to avoid damage to the driver!

Increase output current to 3A:

This step is necessary only for version 1, version R.2 can be set to 3A of the solder bridge.

The output current can be increased to 3A without further notice. Use a 0.1 ohm / 1% / 0805 size

SMD resistor in parallel to the existing resistance which sits at the 200mA soldered bridge and solder

it on. Unsolder the coil, it is advantageous to work better.

The 200mA bridge acts as a 1.2A bridge now. To get 3 Ampere, all solderbridges are closed.

The needed resistors we can deliver.

We tested this setting with up to 8 pcs. Led at 3 Ampere.
