New energy vehicles, hydraulic systems for electric vehicles FL-2 manganin shunt special wholesale DC shunt ammeter shunt supporting non-standard build shunts Overview: Splitter is used to measure DC current, across the resistor when the DC current through the resistor Principle generated voltage is made. At present, many electric vehicle industry are using 300: 75MV DC shunt Case: Ali shop today Customer Inquiry 30A 300MV shunt. At first I thought the client sent the wrong size, so again with the client to determine the 300: 75MV or 30 than 75MV? Customers are sure that is 30A 300MV. For special specifications, is to begin to build sample some trouble. The customer is not happy at first, but then I explained that probably will be able to take up to three business days to issue a sample. And said that if the sample OK, bulk orders, when the ex-factory price real to him. First of all thank you very much understand the customers and friends and promised me to do online trading orders. I believe that a lot of my friends do with industrial opportunities for non-standard specifications. From the manufacturer's point of view we are very pleased to provide customers with non-standard product customization needs! One is to meet customer demand, on the other hand also to cultivate long-term stable cooperative relations. Here we do for DC shunt detailed product description: Application Methods shunt 501W / BP chokes (1) by the ammeter (or current-voltage dual-meter) mV number marked on the dial to select the shunt The rated voltage drop specifications (commonly used is 75mV or 45mV). If no such value is used ammeter, use the following formula to calculate the amount of voltage limit table, then select shunts rated voltage drop specifications. Table limit the amount of voltage (mV) = current ammeter full scale of (A) × ammeter resistance (Ω) / 1000 (2) according to expand their current range selection shunt current rating. (3) selected two current shunts ends are connected to the power supply and the load, potential termination meter, ammeter should pay attention to the polarity of the terminals of the terminal DJ623-8 to pick right, the ammeter range is extended to the splitter the calibration of the current value.
