The quality of survival, reputation and development, ZKJB-2000 intelligent switch monitoring and protection devices and cheap, product quality and safety of your relationship with me, ZKJB-2000 intelligent switch monitoring protection device safety first, quality first, buy ZKJB-2000 Intelligent switch monitoring protection device look Shandong Haobo, not expensive, only buy! 186 * 1368 * 7339 functions and features: (1), dual-CPU design, operation and protection of the display separate configuration management, product stability and speed of operation at the same time guaranteed; (Ⅰ type 16-bit high-speed high-speed single-chip microcontroller +8; Type Ⅱ 32-bit digital-specific processor DSP + 16-bit high speed microcontroller ARM) (2), the use of new high-speed precision A / D converter, the internal integration and synchronization of the sample and hold circuit, without adjustment of external components, good conversion speed stability and low power consumption. With high-precision measurement module, both to ensure the accuracy of measurements (measurement accuracy up to 0.5), but also to ensure the protection of real-time and accurate algorithm;? (3), large capacity RAM and non-volatile memory, used to store and protect the value and event fault data, non-volatile, and long-term recall failure information; (4), high-precision clock design, easy to implement system-wide clock synchronization; (5), can be digitized, online Tuning to protect the value and various operating parameters, setpoint maintain safe and convenient; (6), real-time display and a variety of operational status and data transfer, easy local and remote monitoring and control; both telemetry, remote control, remote, energy accumulation function; (7), the device comes with the operating circuit, without additional other devices can be kick-switch; (8), the product uses the whole Chinese LCD, convenient keyboard and remote control makes computer interaction, user-friendly and easy display understand. (9), the device used in all industrial chip, with perfect electrical isolation and electromagnetic shielding design, the strength of electrical separate arrangement, fully enclosed steel chassis, so hardware device has a higher anti-jamming capability and reliability; (10), highly integrated circuit board design, simple structure, reliable, the main circuit board using multilayer technology and surface mount component technology (SMT), low power consumption, high integration, improved device reliability. (11), three-stage protection can be set separately to speed off, overcurrent and overload protection, various protection current and time value can be set independently for easy system to protect the upper and lower tie, avoiding protection grade trip
