The Charge and Refresh lights do not come on. Since the orientation of primary and secondary windings and the battery (e.g. accumulator) is always the same this pulse also has the same polarity every time. Note that as drawn, you need 4 wires between switch/dimmer locations. 4-way switches are basically interchange devices — the connections are either an X as shown or straight across. The output voltage of this circuit is alternating (+/-) square wave.

Long term reliability is unknown for these non-supported applications. Only one of these should be installed in a 3-way circuit. With no load and the new windings, the output reaches about 5 V in a fraction of a second. The dimmers can be any normal knob or slide type with an off position. Lead acid batteries should stay lukewarm to the touch; nickel-based batteries will get warm towards the end of charge but must cool down on “ready.” Li-ion should not rise more than 10ºC (18ºF) above ambient when reaching full charge.

Electronic Air Cleaner HV Generator At least I assume this cute little circuit board is for an electronic air cleaner or something similar (dust precipitator, positive/negative ion generator, etc.)! I received the unit (no markings) by mistake in the mail. Back to Sam’s Schematic Collection Table of Contents. — end V1.101a —. The square nylon bobbin has a diameter of 5/16″. There is no visible spacer between the cores but I did not disassemble to confirm. Check battery temperature when using a low-cost charger.
