Inquiry (采购产品): Quote Request I need a device that monitors 3-phase, 400 Hz, 120 Volt power system. It must sense improper voltages especially if neutral goes high. It should also have circuit breakers and GFCI. Do you have an off the shelf item? Can you design and build one? It must be military quality. I will need 700 units. Please e-mail me for more info.
