How Can Customers Get Suitable Voltage Stabilizers And Affordable Quotations?

Yesterday I received a call from a customer. As soon as the call was connected, he asked, "Are you a manufacturer of voltage stabilizers? How much do your voltage stabilizers cost?" How should I answer this? Asking the price in this way is like asking how much a smartphone costs? Smartphones are made in China and imported. There are domestic brands and knockoffs of domestic smartphones. There are American, Korean, and Japanese smartphones imported. There are Android, Apple, and Intel systems. This question is too general. The prices vary greatly and it is impossible to quote. Take Huawei, a first-line domestic brand, for example. Huawei phones have multiple series, and each series has multiple models. When you buy a mobile phone, you should at least know which brand, series, and model you want to buy. Otherwise, how can you ask the salesperson to quote you? The price of the same model of mobile phone also varies by more than 1,000 yuan. The price of 4G RAM + 64G memory is definitely different from that of 8G RAM + 256G memory. Our voltage stabilizers are the same as smartphones. Each series is divided into single-phase and three-phase. You can also choose different power sizes, whether there are protection functions such as overvoltage, undervoltage, phase loss, overload, short circuit, etc., whether to install lightning arresters, communication interfaces, filters, isolation transformers, etc., so the customer directly asked me how much the voltage stabilizer costs, and I really couldn't answer. Different voltage stabilizers, different phases, different powers, and different configurations have different prices. Later I learned that the customer wanted Dynamic Voltage Regulator (DVR). The voltage in the factory was always unstable, and the boss asked him to purchase a voltage stabilizer. But when I asked him if the voltage stabilizer was used for the entire factory, he said he didn't know. When I asked what the total power of the electrical equipment was, he said he had to check it out. In the end, I didn't quote because I didn't meet the conditions for the quotation. So how can a customer get a suitable voltage stabilizer and a practical quotation? 1. Know the number of phases and voltage of electricity (such as single-phase 220V and three-phase 380V) 2. Measure the frequency of voltage changes, the highest and lowest voltages in each time period, and whether the three-phase voltage is balanced 3. What equipment the voltage stabilizer needs to be used for, and how much power each device uses 4. Whether to add equipment later, and whether to reserve load power for the voltage stabilizer. With this information, I believe that every merchant will carefully configure the product for you, and the function and power size will not differ greatly, and then you can consider the price, compare prices and place an order.
