The industry desperately needs a compact, economical power solution. Common smart meter solutions integrate only flyback controllers and high-voltage FETs. This architecture is expensive and requires an external voltage regulator and other discrete components to meet application requirements, increasing Plan size and total cost. The power companies and energy companies urgently need a compact, low-cost alternative.
Unprecedented, Highly Integrated Design The MAX17497 is optimized for industry-leading smart meter applications and provides multiple outputs. The device meets all the power supply requirements of the communication and metering circuits in the smart meter.
The MAX17497 integrates the control circuitry required for a universal input (85V to 265V), non-isolated flyback power supply. The device also includes a secondary synchronous buck regulator with a built-in MOSFET. These integrated functions are designed to support the power supply design of power line communication (PLC) drivers or RF transceivers, PLC/RF modems (2.5V/3.3V), and breaker relays, while also meeting high-precision metering, system-on-chip (SoCs). ) Strict voltage regulation requirements.
Meet all the requirements of smart meter power supply for flexibility, accuracy and reliability The MAX17497 offers great design flexibility. Regardless of the communication mechanism used, designers can configure the device to meet the power requirements of the smart meter.
The flyback regulator is designed to work at 250kHz/500kHz, avoiding the smart meter communication frequency, thereby reducing frequency interference and ensuring reliable performance. The magnetic and filter components in the smart meter can be optimized for the operating frequency of the high-voltage flyback regulator and the secondary-side buck regulator.
The MAX17497 also improves overall system reliability through user-definable thresholds and protection features. Under-voltage lockout (UVLO) and overvoltage threshold inputs are programmable, and over-temperature, short-circuit protection, and power-good indications greatly increase system safety.
The MAX17497 is available in a small 3mm x 3mm TQFN package and operates over the -40°C to +125°C temperature range.
The tire protection chain, also known as the loader anti-skid chain, has a chain ring, connected between the main chain members, link on both sides of the chain ring side chain and link on both ends of the butt chain members, on both sides of the chain ring is equipped with two ends of the fastening rope with rope card, the main chain members for the open type. Tire PROTECTION CHAIN IS a kind OF TIRE protection equipment MADE OF advanced production technology at home and abroad, using high quality alloy steel materials, precision casting or forging, high strength automatic flash butt welding, reasonable braid structure and special welding technology
The maintenance chain has good wear resistance and strong fatigue resistance. The service life can reach 3000-8000 hours according to the service conditions. Tear open outfit is convenient, save time and effort, the products are complete in specifications, can match with imported loader, tyre protection chain, using high-tech wear-resisting material, the new structure is compact, stable performance, mainly is suitable for the mining operation of the loader, the tire wear fast, short service life, the tire is expensive, the cost is high, will this product tightly wrapped in loader tires, Can effectively protect the tire of the loader, not be punctured by sharp stones, prolong the service life of the tire, the use of a tire protection chain, can save more than ten tires, but also can improve the efficiency and safety of the loader is a necessary part of the mine operation.
