1) There is a corresponding relationship between the working voltage and the flameproof category, see E.2.1 “Product Introduction” for details.
2) When AC power supply, the electromagnet is embedded with a rectifier circuit, and no external rectifier device is required.
3) The power supply is capable of providing instantaneous power of 18W.
