Finest damper on ebay - check out these Belimo LMB motor features, including a 5 year factory warranty: *Uses Belimo’s commercial grade LMB24 90-second 3 wire motor on a commercial 1/2 inch drive shaft. *Not a stripped down OEM motor or a cheap look alike import - this is a genuine, full-featured LMB24 Belimo motor. *24volts AC or DC, internal brushless DC motor with microprocessor control - the most reliable motor we have ever sold in our over 35 years in business.*Motor internally senses amperage change at end of travel and kills power.*Easy motor travel adjustments allows precise bypass air, if desired. *Can be controlled directly by a thermostat - no relays needed as required with other 3 wire motors. *Uses only 2va intermittent power compared to the 9va continuous power used with residential spring return dampers. *Powerful commercial grade 45” lb 90 second silent gear drive motor handles 2” of static pressure (4 times greater than residential) - no spring flutter and never gets hot.*Hi torque allows installation right at air plenum, and will open and close reliably in full force air stream situations. *Clutch on motor allows damper to be fully opened or closed for installation and testing*Reversing switch on motor allows unparalleled flexibility. *Commercial 1/2 standard drive shaft means thousands of different motors can be retrofitted, in the future, to this damper. Specifications:*Standard Belimo LMB24 90 second motor uses 24VAC or DC. *Damper comes undersized 1/8” in both dimensions to slip inside duct. Use self adhesive weather-strip to close any gap. *90 second actuation time for this damper. Other motors/timing available at additional cost.*Frame is 2 and 1/8” wide, end plate is 5” wide. *Weight varies by size. Typical weight is 6 lbs for 16x16” size.*Industry leading 1 blade per inch design offers better air control and less noise compared to wider blades. *All aluminum and stainless steel construction for this damper.*Air control pressure rated 2” static pressure (4 times maximum residential static pressure of .5”).*May be set to any minimum/maximum air flow with motor limit screws.*May be used with optional SPDT center off switch to stop blade anywhere in arc of travel (see technical support information below).*Optional snap on end switches available to verify blade position. Additional Technical Support Information: Only 2 wires to your present damper? Replacing 2 wire dampers: Many users tire of replacing 2 wire spring motors as spring return motors have a higher failure rate for two reasons: (1) overheating since they pull power continuously when energized; and (2) additional stresses of the spring. The SD3085 does require 3 wires between the zone panel and thermostat. Check the cable running to your present damper, as many times 4 conductor cable is run, with only two wires used. Many zone panels are already set up for 3 wire dampers. Check your damper outputs to see if a “norm open” or “M4” terminal is present and unused - if so you are good to go! If your zone panel has just a 2 wire output, you can still use this damper by using a third connection from the zone panel thermostat “R”, which is the continuous hot side of the transformer. Controlling directly from a thermostat with no relay needed: You can have the advantages of 3 wire power with no relay when connecting directly to a thermostat. Here is how it works: Since the Belimo LMB motor is “smart”, with an on-board microprocessor, it has a couple of wiring tricks. In this case, 24vac power is wired full time to terminal 1 and 2 on the motor. Then, the jumped W and Y outputs from the thermostat are wired to terminal 3. Anytime the motor gets power from the thermostat on terminal 3, the dampers open and when the thermostat drops power to terminal 3, the damper closes - It's that simple. No relays, and 3 wires means no wasted heat or hot motors. You can also operate the damper from a simple single pole light switch, in this same manner. Stopping Damper anywhere in its range: The Belimo LMB motor features a gear train that will hold the damper blade in position, in the air stream, when power is removed from the motor. So, when used with a single pole, double throw, center off switch (SPDT center off), you can stop the damper anywhere in its arc of travel and it will hold its position. This is great for air balancing applications. Dampers are all we do! Check our ebay store damperdirect for more parts. We are a full line Belimo motor distributor.
