Types of Bikes Once youâve determined where youâll be riding your bike, how often youâll ride, whether you have any health concerns, and how much money you have to spend, itâs time to choose the type of bicycle that best fits your needs.
LPS circuits are those circuits powered by the output of a Limited Power Source. LPS circuits are connected to the load side of a fuse, circuit breaker, PTC, or regulating network. The circuits on the supply side are not powered by LPS, and must be provided with a fire enclosure.
Velocity fuses work by sensing flow across a control orifice when the pressure differential exceeds a predetermined amount (usually 50 psid). A spring-biased poppet closes, shutting flow to the damaged hydraulic circuit. A velocity fuse requires a flow potential large enough to meet the differential pressure setting.
