Control ac to slb-ext to turn on and off?

Is it ok to just power on and off slb-ext on my altmill from the ac side instead of using the switch on the slb-ext itself. can i just leave the slb-ext switch on and then just control the slb ac power from a switched outlet?

I sure hope so as this is how I’ve been doing it for over a year… I didn’t realize the SLB-EXT had a power switch.

@kdsvs1999 My SLB, not the EXT model is plugged into a power bar, and I kill that with a large paddle switch. Like @whitewolf, I can’t remember ever using the small, hard to get to, switch on the SLB.

Hey Kevin,

The reason why the power switch is on the dc side is partly to disconnect the slb from the secundairy side of the inductor. A inductor or coil, is a clean short when you measure it with an ohms meter. This makes sence because all a inductor is, is an x-lenght of conductor wound into a coil. To a dc current, it is nothing more than that conductor once the initial magnetic field lines have been established. And herein lies the crux. An inductor is working against change due to these magnetic fields.

I like to analogue it with petting a cat. If you firmly stroke a cat on one side, it will lean into the stroking as firmly as you are stroking. When you, for lollsz, suddenly retract your hand, the kitty will fall flat on the side you were so firmly stroking a second before. To prevent falling it will instinctively use it’s claws leaving you with a few pricks or complete red stripes running down your legs.

A coild will do exactly the same. Since the secundairy side is the side with the lower voltage, the reaction of the secundairy coil will be to prick your legs. When you cut the primary coil though, you are retracting a stroking hand that was petting with a tenfold as powerful stroke resulting in scratching claws spiking into a still turned on slb. Will it kill a SLB? Not if it’s a new one, no. But please note that 90% of electronics that break, worked the day before. Electronics mostly break due to this spike induced by turning off a device. The remaining 10% is spilled coffee.

I am ofcourse pulling whitewolfs legg here a wee. There are capicitors in place to eliminate these spikes.

Yeah, you can turn of the ac side, untill these capacitors give out.
