Why should I use an LED controller for DCC power?

• Even the the best decoders only provide +5, +10, and +22 (track rectified +) volt outputs. Any of these outputs will require you to add a dropping resistor to each LED to set the current or you might use the +5 volt output and dim the decoder output to 3/5*32 to get ~ about 3 V and this will remove the option of dimming the leds using the decoder output dimming function automatically or manually due the coarseness of the 1/32 steps of CV dimming control..
• Because the DCC track voltage varies the brightness of the LED brightness will vary.
• Some decoder dimming outputs fail to work and could deliver full track voltage or 5 volts and burn out the LEDs.
• The only safe and efficient way to power LEDs is to use an SL LED controller that provides:
  • A save and remote way to dim the LEDs on each decoder output without the need for resistors on each LED
  • A convent want to dim up or down automatically by using the ventilator output setting on ESU decoders so the Lights increase in brightness (dim up) when coming on and decrease brightness when turning off.
  • Archive Up to 97% efficiency
  • Safe operation of LEDs without dropping resistors on each LED

How do I use the DCC decoder with the SL 8453003?

• Wire all LEDs on the same decoder output in parallel.
• Remember to connect the decoder ground (GND) the the GND on the Shourt Line LED controller. The - LED output wire on the SL 8453003 is connected to the ground (GND) on the controller.
• The SL 8453003 + LED output wire always supplies the safe LED output voltage of your choice
• The SL 8453003 + LED output is connected to as many as 200 LEDs or 2 amps of current.
• The - side of each LED connects to an output on you decoder. When the decoder output is on the - side of each LED is returned to ground by the decoder and both the decoder GND and the SL LED controller GND are connected together to ensure a ground path of the - side of LEDs when the decoder output is ON.

Instructions and precautions:

• When powering LEDs always set your output voltage to the maximum LED forward voltage (3.1 volts for Shourt Line warm white LEDs) and the maximum LED current
• Wire LEDs in parallel without resistors.
• Always use a test LED with the SL LED controller BEFORE connecting to your lighting fixtures.
• Never connect input to more than one power source.
• Never connect a power source to the output of the LED controller.
• Clean the surface with an alcohol wipe prior to using the 3M adhesive pad included with many models of the Precision Throttle and LED controller.
• Provide adequate ventilation when powering over 2 amps or 10 watts of load
• When used with a decoder, always connect the negative GND output to decoder GND
• Not a toy; keep out of the reach of children, can cause choking due to the small size.

How does it work?

All Shourt Line Precision Throttles and LED controllers feature a DC to DC converter operating at high frequency to efficient convert input power to any desired voltage lower than the input voltage. It stays cool because of the micro size high frequency inductor and provides fully regulated output voltage regardless of variations in input voltage. a capacitor provides stable output voltage for minor input fluctuations. For anti-flicker protection due to dirty track or dirty track use an external capacitor connected to the bridge + and - (GND) leads. Anti-flicker protection can also be achieved by adding more power pickup points from the track. Contact us for details.

Power Over 200 LEDs with up to 97% efficiency for cool operation, with very low power loss.

Use 1 Shourt Line Precision Throttle & LED Controller to power any of SL LED drop ceiling lighting, tiffany or wall mounted scale lighting fixtures on Analog, battery, or DCC track power.

Overview: Because a white LED uses only about 3 volts but the track voltage can be as high as 22 volts, the difference between 3 and 22 volts or 19 volts is wasted as heat when resistors or LDO voltage regulators. This is booth inefficient, 19/22 or 86% of track power goes up in heat, and when track power is say lowed to 6 volts at slow train speeds with analog power the output of the light is reduced by (22-6)/22 or 73% while each dropping resistor still wastes power. This is why we or controllers use electronic high efficiency DC to DC converters that regulate output voltage at different input voltages or output currents (number of LEDs powered).

Prior to the induction of the Precision Throttle and LED controller we at the Shourt Line had to versions of each lighting product; one for DC (analog) uses and one for DCC users. This was necessary in order to efficiently at low track voltage and high track voltage respectively. We now have a version of lighting fixtures for use with the new Precision Throttle and LED controller that works efficiently with both low and high track voltage.

The micro size allows the Shourt Line Precision Throttle & LED Controller to fit between the drop ceiling and car roofs or can be mounted inside or under cars.

Simplify all your loco, car and layout lighting with the SL 8453003!

The SL 8453003 features a built in AC to DC rectifier for connecting to the track power using DC (analog), DCC or AC at 4.5 to 24 volts.

Note the blue tube on the input power cable that comes out below the LED output cable that has no marker tube. The EN control pad can be optionally connected to GND to disable the output.

When you received the SL 8453018 it will be soldered to 5V track pads as shown above. This gives the output a voltage of 3.05V and can be adjusted in the range of 0.9 to 4.2 volts. This is perfect for controlling White LEDs.

The SL 8452024 controller inside the case can also be set to a fixed voltage of 1.8, 2.5, 3.3, 5, 9, or 12 volts when a voltage is selected by soldering pads and IF the adjustment pot is disabled by cutting the trace shown in red above to the right side of the ADJ solder pads AND the ADJ solder pads are NOT soldered.

Note that IF the red trace shown above is cut and you want to re enable the adjustment pot you can solder the trace pads above the 'ADJ'. The 5V track pads shown above are an example of how to solder two pads. Soldering the ADJ pads will restore the controller for adjusting to white LEDs. In addition, if the pot is enabled and no voltage tabs are soldered, then the output voltage can be set from 0.9 volts to input voltage less ~2 volts. This setting can be used for LEDs but you will find it hard to get the desired brightness (output voltage) as the adjustment is very course due to the wide voltage range.

Note the LED cable has a copper wire for + side of LEDs and a silver ribbed output wire for the - side of LEDs that connect in parallel without dropping resistors. Note also the access hole in the top of the controller for accessing the volt adjustment pot. Always adjust the voltage with test LEDs before connecting to your lighting fixtures. Start at 3.05V output and slowly adjust down or upward for desired brightness using a test LED but do not exceed 3.1 volts or the manufacture's recomended maximum voltgage to avoid damaging the LED. Follow the instructions we provide for setting the desired brightness without exceeding the manufacture suggested maximum forward voltage (Vf) and current.

Mounting examples:

The SL 8453018 Micro Size LED controller is delivered with a 3M adhesive mounting pad and without the back cover cemented in place. We recommend either asking us to do this for you at the time of order or you can do it yourself by applying a 1/3 drop of E6000 clear cement with a tooth pick to the locations shown below and wait 24 hours before mounting the case. The E6000 should hold the lid to the case and the 3M adhesive mounting pad will allow the case to be un-mounted when needed without damaging the case, the mounting surface or the rear lid.

The back side of the lid has a 3M outdoor adhesive pad for mounting. After confirming the lid is firmly cemented in place, peel off the red tap protecting the 3M pad and press onto a mounting surface that has been cleansed with an alcohol wipe. The 3M pad can be removed if desired and the case can be mounted or cemented in place without the 3M pad. The advantage of using the 3M pad is that it will hold the case securely and can be later removed without any damage to the mounting surface.

The SL 8453018 Micro Size LED controller size fits where other devices do not. It can be mounted in side loco cabs, in locos, in track side buildilngs and under passenger cars and on car ceilings.

The size of the SL 8453018 Micro Size LED controller is 34mm L x 13mm W x 9.25mm H (1.34"L x 0.5"W x 0.37"H).

Examples of where to mount the SL 8453018 Micro Size LED controller in passenger cars:
