Product Details
This industrial - grade 50W high - power step - down module is a top - notch choice. It accepts a voltage input from 9V to 18V and can deliver a maximum output of 5V at 10A. With a high isolation withstand voltage of 1500V DC or 800V AC, it significantly reduces radiation interference and ripple noise. It comes with short - circuit protection and input under - voltage protection, making it extremely reliable. This converter is widely applicable in various industries such as portable power supply systems on chassis, railway locomotives, new energy, communications, electric power, and industrial control, especially in occasions where input and output isolation is required. Here are the pin details: Pin 1 (FG) is the shell, Pin 2 (+Vin) is the input positive, Pin 3 (-Vin) is the input negative, Pin 4 (CNT) is the control foot, Pin 5 (TRIM) is for output regulation, Pin 6 (NC) is floating, Pin 7 (-Vo) is the output negative, and Pin 8 (+Vo) is the output positive. To control the module, set CNT floating or connect it to TTL high level (3.5 - 12Vdc) to turn it on, and connect it to GND or low level (0 - 1.5Vdc) to turn it off. Key features include up to 50W output power, high isolation, low interference and noise, an environmental - friendly RoHS - compliant design, and a wide working temperature range from - 40°C to + 85°C. The specifications are: Input Voltage 9 - 18V, Output Voltage 5V, Output Current 0 - 10A, Output Power 50W max, Conversion Efficiency 83%, Insulation Voltage 1500V (input - output, test time 1 minute, leakage current < 1mA), Input - Shell (FG) 1000V, Output - Shell (FG) 500V, Working Temperature - 40 to + 85°C, Storage Temperature - 55 to + 125°C, Storage Humidity 5 - 95%RH. The shipping list includes one Industrial Isolated DC - DC Buck Converter (9 - 18V to 5V 10A).
Using this industrial isolated DC - DC buck converter is quite straightforward. First, make sure to check the wiring before powering it on. Connect the input positive (+Vin) and negative (-Vin) pins to a power source with a voltage between 9V and 18V. Then connect the output positive (+Vo) and negative (-Vo) pins to your device that needs 5V power. You can control the module using the CNT pin. If you want the module to work, leave CNT floating or connect it to a TTL high - level voltage between 3.5V and 12Vdc. To turn it off, connect CNT to GND or a low - level voltage between 0V and 1.5Vdc. Here are some important things to keep in mind. The power module will get hot after being powered on for a while, so don't touch it with your hands or body to avoid burns. If you're testing the insulation withstand voltage between the input and output, short - circuit all the pins of the input and output terminals respectively before testing. When the product shell temperature goes beyond the specified value, you need to think about adding heat dissipation measures. For maintenance, there isn't much you need to do regularly. Just keep it in a dry environment with a humidity between 5% and 95%RH. And when you're not using it, store it at a temperature between - 55°C and + 125°C.
