I am writing to ask if I should post details of my power monitoring system. It watches voltage and current sinewaves of household power and samples them into memory simutaneously and then performs KVA/KW, PF and other calculations which are transmitted via rf to a handheld receiver. It...

This is my latest project I just completed. It is a multi-channel lead acid battery charger. It can be used for VRLA, gell cell and wet cell types. It is designed to charge battery jars with a nominal voltage between 4 and 12 volts. It will also work well with any battery type requiring a...
