Straight-meter wall, Winbond meter (certified), wall Meter

Many Connection type meter, single-phase meter connection straight-meter wall, there are three-phase meter connection; there is a direct connection type, but also through the current and voltage transformers wiring. But in general, there are only two circuit: voltage loop and current loop. Meter wiring general principle is: the current series with the load coil, or secondary school wall meter, voltage coil parallel with the load connected to the secondary side voltage or transformer connected to the current transformer. Pure single-phase meter generally contains only a basic measuring unit in rural wall meter, an electronic counters and a light emitting diode and pulse output, etc., the whole power consumption is generally not more than 50mW wall-meter, low-cost series RC down circuit to meet the power needs of the entire meter; some metering IC requires only a single + 5V power supply, such as ADE7755, etc., shown in Figure 1. While others require metering IC Dual ± 2.5V or ± 5V power supply, straight-meter wall, Winbond meter (certified), wall meter by Winbond Power Technology Corporation. Winbond Power Technology Co., Ltd. (www.china-huabang.com) (www.hbdlyb.net) is Wenzhou, Zhejiang Province, electrical instrumentation leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Winbond meter leadership with the staff warmly welcome all inquiries negotiations to create a better future for Winbond instrument.
