M-23A, M-23B, M-3 and Low-Profile M-3 Electric
... The M-23A uses a different hand-throw pinion than the M23B, which affects hand-throw locking. Power operation is the same with both machines. In the M-23A, the hand throw lever gives the same mechanism stroke and full lock rod protection as the power operated mode. In the M-23B, however, the lever d ...

Solenoid Coils for Switching and Proportional Valves
... Generally speaking, TVS diodes fail closed, shorting the coil and rendering it useless. Excessive surges, spikes, and over voltage will cause the TVS diode to fail. Great care has been taken to size the TVS diode to prevent nuisance failures. Sun 760 coils come standard with a Metal Oxide Varistor ( ...

Newly Developed Iron Powder for Highly Efficient Dust Cores
... A dust core with an iron loss of 28.6W/kg was produced. This core is comparable with ones made of laminated steel sheets. Introduction To decrease the environmental burden and to save energy, there are growing needs for electromagnetic components with reduced loss. Components such as photovoltaic po ...

Control Systems for Marley cooling tower fan motors
... Good practice dictates using dual-element fuses rather than one-time fuses. Dual-element fuses interrupt higher fault currents, generate less heat in the control box, and permit use of smaller fuses for better protection. In addition, if a fuse clip is loose on a one-time fuse, the case can carboniz ...
