Max how did you find the Ls150 worked is it a very positive throw i am used to throwing points using a CDU but i think im correct in saying with an Ls150 you cant do that? I have one here i have never used so i am thinking of using it but was unsure how well they throw points peco solenoid type ones Brian |

Brian, the LS 150 can be used to throw any kind of turnout motor, as you probably know. I've re-read your question, but I'm still not sure what you are asking. The LS 150 can deliver enough power to drive the Tortoise motors and can be set (once you decipher the manual), to deliver a pulse of any length. I have set mine to 2 seconds, which is plenty for a Tortoise. The way I have mounted the Tortoise with the double pivot gives a terrific amount of back pressure, so it isn't necessary to have the motors stalled to keep the blades in place. (Important for RR&Co). The things I like about the Tortoise motors are that they operate on low current and that they don't slam the mechanism of the turnouts. As I understand it, the current from the LS 150, while being AC, is a bit under spec. for solenoid motors and should be used to drive a CDU, via a relay. Does any of that help?  ____________________ Max Port Elderley |

Yes Max the last bit you say for solenoid a Cdu is needed that i use at present but my CDU does All 42 points With the Ls 150 i assume any Cdu would have to go after the Ls150 otherwise it may blow it up im not sure about that. If its after either 6 seperate CDU`s or some sort of relay arrangement would be required i would have thought. I think what i am saying is does the electronics on the ls 150 gets its power from the standard dcc track feed if so thats fine and does the power that sent through the six contacts come from elswhere and does not affect the electronics as it passes through only in that case a CDu could be before the LS150 does that make sense?

I think you will find it worth reading. |

You can power the LS 150 from the track bus Brian, but I made a separate power supply from a Toroidal transformer and ran the 16VAC straight into the LS 150.

Sorry to make a correction here but the LS150 must be powered from a separate AC power supply. The only connection to the DCC bus should be J&K terminals to receive the DCC signal when point/s are operated. Lenz advise max 16v ac which causes the LS150 to struggle to fire Peco solenoid type point motors. All my LS150's are powered with 18-20 volt AC 5amp. Yes 18-20v, which I have been doing for over 7 yrs with no problems what so ever. Have not blown one up yet. All my points are Peco with surface mounted Peco point motors. Some even have the cheap SPDT Peco switch attached which operate 99%.of the time. Nothing is ever 100%. I have a number of cross overs(two points op in tandem) that operate with no problems. I do not have any CDU's. Don't be frightened to up the power supply voltage to LS150's. As I said, after 7 +yrs the 12 LS150s on my layout have never failed.

It's the LB 101's and the LR 101s I have hooked up to the track bus. As I said, I built a separate power supply for my LS 150. I don't have any solenoid motors, so I don't really know about them. ____________________ Max Port Elderley |
