Case Details


Main Technical Parameters [For reference only]

 

Equipment completeness

 

 

(3) Strong Excitation Power-Off Magnetic Retention Operation Mode: At the moment of lifting, the output voltage is DC 290V; after the material is lifted, during the transportation process, the output voltage drops to DC 200V while maintaining magnetic retention even in the event of a power failure.

1. There are three operation modes.

(1) Controller or instrument panel operation mode

(2) Digital remote control operation mode

(3) Fully remote-controlled operation mode for both digital and analog signals

 

3. Non-contact control: This approach employs a three-phase active, controllable inverter circuit with full-control rectification for forward excitation control and a two-phase fully controlled rectifier circuit for demagnetization control, thereby abandoning the traditional method of using DC contactors to control magnetization and demagnetization. As a result, the system operates without electric sparks, noise, or mechanical vibrations, significantly extending its service life. During demagnetization, the residual energy stored in the electromagnet is first fed back into the power grid, eliminating the need for high-power resistive snubber circuits typically used to maintain current flow. This not only reduces energy consumption but also achieves energy-saving goals.

4. Utilizing the latest microcontrollers for digital, contactless control, the device features key-based operation for function and parameter settings. Fault alarms and interface parameters are displayed on an LCD screen, and set parameters are automatically saved. The phase shifting, pulse width regulation, and modulation of the pulses have all been digitized. During operation, the trigger section requires no adjustments whatsoever. This device boasts high reliability, strong anti-interference capability, fast response speed, and ease of use. The equipment is equipped with functions such as automatic phase detection, phase-loss protection, soft start upon power-on, circuit-breaker protection, overcurrent protection, overvoltage protection, operational status indication, excitation fault detection, and charging fault detection.

5. Integrated modular design and production, utilizing programmable controller technology, and featuring exclusively advanced international or domestic brands. Internal components are designed in a modular fashion with a rational layout, minimizing external wiring and ensuring convenient connection and disconnection. All components can be replaced from the front of the board, making maintenance and troubleshooting extremely convenient for users. The equipment boasts high operational reliability and safety, with a low failure rate.
