Heavy Duty (HD) actuator: this is a standard stock actuator kit (60+ lb lift) when you need to open a heavy skylight. It is an unobtrusive 12 volt electric window opener for skylights, controlled by our RF remote control (5 ch), with a rain sensor (includes power supply also).
Please note: this is a this is a standard stock actuator from our manufacturing facility. It includes remote control + rain sensor. We have tested it to 60+ lbs.
The WTK-12v-RR-HD is the part number for the KIT (with 5 ch remote control and power supply), and the WT12v-RR-HD is the single unit that you can add to the kit if you have multiple skylights that you want to add to the remote control.
You've seen how handy our window blind and shade systems are, now you can use the same safe, low voltage technology to open and close your skylights. The flex link direct push stroke is 12" (300mm), but it can also be stopped at any point if you want your skylight only slightly opened.
The opening/closing force before obstruction is sensed is approximately 60+ lbs (27+ kg), current consumption is ~2 Amp, protection class is IP32. These units have been stress tested to over 3,000 openings.
If you are planning to use this for a skylight opener, note that you can check the force required to open the skylight by standing on a bathroom scale and pushing up on the skylight with a long broom handle or other suitable pole. If your skylight is heavier than the actuator capacity, you can offset the extra weight with gas shocks, torsion springs or external counterweights.
PLEASE NOTE: Window and skylight openers can be dangerous to children, adults and pets as they normally have a considerable amount of force that is used to draw the window closed and provide security. There is more than enough force to crush fingers of small children and/or cause injury to adults, pets, or other animals.
The linear chain actuator pushes straight out from the fixed housing which lines up unobtrusively with your skylight frame, fastened in place with mounting screws. Attach the end of the chain actuator to the window with two screws and you're done!
Use it to control the motion of anything you want, including skylights, windows, greenhouse vents, etc. The stroke is fixed at 12" (300mm), but it can be stopped at any point of travel.
If used with our digital radio control system, it can also be used with our Broadlink hub (see https://NodeSwitch.com for more info about the Broadlink hub).
Care should be exercised when these units are installed where adults or children could get fingers caught in a closing window - serious injury could result. Use of insect screens can help eliminate this possibility.
PLEASE NOTE: Whether it is blind motors or window/skylight openers, you do not need to be concerned with high voltage shocks because these units are operated on a low voltage of 12v DC (no shock hazard), using an AC/DC power supply (or 12v DC battery). It is good practice to connect your AC line as close to the 12v DC motor as possible, and to keep the DC line as short as possible, using at least lamp cord (16 gauge) wire for the 12v DC line. You can also use your car battery to test them.
