PD20G series electric motor intelligent protector
1、 OverviewPD20GThe series motor intelligent monitoring and protection device is an intelligent instrument that improves the safety and automation management level of motor operation. Its core is developed from high-performance integrated circuits. This instrument has complete protection functions, intuitive parameters, sensitive and reliable response, and can communicate with the upper computer to form a high-tech product that integrates remote monitoring. Widely used in industries such as petroleum, chemical, coal, metallurgy, power, steel, cement, mining, light industry, textile, etc., it is an ideal device for low-voltage motor protection and remote monitoring. 2、 Feature 1: Adopting microcomputer technology and high-performance low-power circuits, with high-speed operation and stable performance. 2. Modular structure of the whole machine, card type current sensor, small size, easy installation. It can also be installed separately (distance ≤ 5 meters). 3. Using digital processing technology, it has high measurement accuracy, good linearity, fast fault diagnosis speed, and * * reliability. 4. Set parameters, measurements, and fault codes, displayed on the LED for clear and intuitive display. 5. Equipped with RS485 communication interface, it can communicate with computers to form a remote monitoring integrated motor protection network, facilitating centralized control and management. 6. One machine is versatile and can replace ammeters, thermal relays, time relays, working power voltmeters, etc. 3. Scope of application and usage conditions 1. 380VAC, 660VAC three-phase asynchronous motors, feeder circuit protection. 2. Protector power supply voltage; 220VAC ± 15%, 380VAC ± 15%, 50HZ ± 2%. 3.
