Is this latching? If not, what is the current draw when active?

You're right to be confused, R. S.See my question about what that schematic is supposed to be for.Read the comments to the answers to find the scoop on this solenoid.

Do yourself a favor and buy the Intellitec Battery Disconnect Relay or Parallax disconnect.

It draws no power engaged or disengaged. Small amount of power used to engage or disengage.

Mine works great and always has. The fact that a display cycles probably means that you have it hooked up wrong. In normal operation, one bar stays lit or flashes when low. Remember that the positive and negative have to ALWAYS be hooked up to your battery pos. and neg. I've got a switch on mine to turn off the display but it's not really needed. One user says "The C is for your switch to turn on the indicator, with my application, I ran a wire and connected it directly with the positive terminal for the indicator, beings I want to be able to kill power to the entire indicator when not in use. Prolly wasn't needed but that was my choice and it works great. The R is unused and I think I read that it's not commonly used." On mine, I think that means that when I installed it I hooked pos to battery pos and neg to battery neg. Then I hooked a wire from C to my switch and back from the positive pole on my switch to neg on the indicator. If you don't put in a switch, then I believe C just gets hooked straight to positive so that the unit will display.

mine latches and stays put just fine, there must be an issue with that one.

It latches just fine. The problem I had was that it would never unlatch even after hours of trying and talking with the company trying to resolve the issue.

Andy - I connected my contactor to a Variac and measured the coil current. I measured the following: Pull-in current 145mA to 155mA. Sustaining current 60mA. Drop out current about 30 mA. The solenoid buzzed really badly if the available current was LESS than 145 mA at pull-in, which leads me to believe that your problem is the output driver on the motion sensor can't provide enough current to pull the contactor in. You can measure the sensor output current to the contactor coil by CAREFULLY connecting a multimeter, set to the 10 amps AC scale, in series with your coil drive circuit, and monitor the amount of current it's putting out while the contactor buzzes. Be careful, 120 volts. If your driver can't provide the current to drive the contactor, one way around this would be to use a second, smaller relay to pull in the bigger contactor. Typical "ice-cube" 120v coil relays just require ~ 10-20 mA to pull in. Then this small relay's contacts could activate the coil of the larger contactor. If your motion sensor is providing the proper current then the problem may be related to noise, but I'd check your driver circuit's current capability first. Greg Walz greenlite350@aol.com

Yes and yes. Don't maintain power for long periods. Burned one out when switch got stuck in the on position. Also retraction is not very strong. Any pressure on the latch will prevent retraction.

I have the same issue with one of my switches, it is ON all the time, have seen similar comments, it appears to be a common failure with these units. With that said I view it as an inconvenience not a safety issue. The output is only 12V and as long as each individual output is protected (as described) then each one should trip if it gets shorted or overloaded. However to be safe I would unplug the whole unit anytime you mess with the output wiring.

I'm pretty sure it's "hot", the trigger just causes the wire to feed. I don't see why that would be a big deal. Turn the thing off when not in immediate use. Probably some regulatory goon, industry or union person looking for an "issue" to limit competition.

Hmm ... not sure what you mean by "clamping time," but if the question refers to time between detection of power surge/undervoltage and active suppression/correction, I would have to assume it's nanoseconds. The incoming current has to travel through the device before it passes out the other end, and it isn't doing that before the incoming current is "conditioned" ...

The contactors close when the signal pins are brought high, when released (grounded) the contactor will open. So, they do not remain latched.

Measured Draw at 13.2volts is 2.4 Amps, just purchased the product in December and connected to a Voltage/ Amp draw meter and there is no initial "strong" draw, just constant draw at 2.4 amps, this unit is running off a battery storage unit, charge by solar panels, for my fish pond in my Aquaponics System

This is common to some laptops... I have had duplicate computers and one works great the other does not even when the batteries are switched. I have just gotten into the habit of putting a piece of black tape (duct type) on the latches and a very thin strip on the underside of the battery along the entire length of the battery. Now I can be a lot rougher with my laptops around with no concern over losing the battery. The latch tape is enough but I a particularly rough with my net-book. The HP by the way does not have a latch problem and I still tape it.

The package lists 15mA but measured only 11mA of parasitic draw. The draw is because of the led, and is pretty good, but I added a switch to turn it off. My camper has about 100mA parasitic draw which is high when compared to a typical car of maybe 30mA.

As with most voltage converters, it only activates with a draw on it. As for me, mine is fused and switch controlled, just in case.

No problems with ours, have been using it for a couple of months now. Latch is tricky, and easily broken.

If the side clamps are not securely down it will not operate. This is a safety feature and it is very sensitive. Try adjusting the catch basket and the top making sure everything fits well then retry. It can be sensitive. To check you can try pressing in the side clamps while the on switch is on. If it activates then it is exactly what I am talkin about.

Not much at all. Mine starts on the second pull 95% of the time. I've never had a problem with mine.
