Latest news: Our company produces analog circuit breakers and analog circuit breaker operation screens with touch screens, which can be remotely controlled through WiFi. If old users need to upgrade, please contact our after-sales service department or dealer for paid upgrade

PRS-101MThe intelligent analog circuit breaker is adopted by our company on the basis of the original analog circuit breakerARMA new type of product developed using a microcontroller as the control core. Due to the use of a new type of microcontroller and program control10The touch screen performs all parameter and switch operations, abandoning all mechanical buttons or knobs, thereby improving the accuracy and performance of the entire machine. This product has the characteristics of reliability, durability, easy wiring, small size, and light weight. It is equipment for testing relay protection devices. It can be used in conjunction with various microcomputer based relay protection testing devices to complete the experimental and testing work of complete sets of relay protection devices for various voltage levels in the power system relay protection department, ensuring the integrity and reliability of the complete set of relay protection devices and improving the calibration quality of the devices.

• Performance Characteristics

1. This machine comes with a high-precision programmable DC voltage regulator and constant current power supply for users to use when there is no DC power supply.

2. This analog circuit breaker input control terminal can input AC/DC current signals to trigger the action of the analog circuit breaker. Thus, the operating characteristics of AC/DC circuit breakers can be simulated. Greatly convenient for users.

3. This simulated circuit breaker adopts a low-energy design and is equipped with a large capacity lithium battery. It can be used continuously without AC power supply on site10More than hours, standby30More than an hour. When using internal power supply, the DC output power supply provided by this machine is not available. (This function is an optional feature, please specify it when ordering)

4. This device adopts a modular design, which can be infinitely expanded by adding tripping and closing modules and control units. Can be formed2Analog circuit breakers with more than one circuit can form multi circuit analog circuit breakers, which can simulate the actions of multiple three-phase circuit breakers. Multiple analog circuit breaker input and output circuits are isolated from each other, and when the tripping and closing coil currents are used in parallel through corresponding channels, the current can be doubled, thereby achieving more functions. It can also be used to form a simulated circuit breaker screen for teaching and experimental purposes.

5. This device can be operated and controlled through a tablet or mobile phone, and provides upper computer software.

In summary, this simulated circuit breaker can simulate the automatic reclosing test of AC/DC circuit breakers, automatic backup power input test, and three-phase different period tests.
