Rack PDU Power Rating vs. Load Capacity
Load capacity is specified in VA where the amps are the rated current, i.e., the derated value. For example, for a single-phase rack PDU with a nominal voltage of 208V and maximum line current of 30A, the rated current
Power Tools: How Much Power Do They Need?
Power tools have big appetites. The moment you turn them on, they gobble up more than their fair share of electricity. As a result, you have probably tripped a few circuit breakers in your shop while feeding your power tools. To
Battery Run Time Calculator
To estimate how long your 12V, 24V, and 48V batteries will last, you need to know a few key details: The battery capacity (in Ah or mAh) and the power consumption of your device (in watts or amps). The battery runtime is
RC Car Batteries 101: A Guide to Type, Sizes, and
Many NiMh batteries have around six or seven cells and one cell usually spends about 1.2 volts. You will see these sold as "6-cell" or "7-cell" packs. LiPos work with the same principle, but one cell of LiPo spends about 3.7 volts and LiPo
