24VDC Industrial DC Power Supply Standard

Feature & Principle

24VDC power is generally converted from AC through switching power supply. It provides safe low-voltage power for field instruments and control components. It can be divided into positive and negative poles, supports two-wire and three-wire sensor wiring. It has good anti-interference performance, and many devices support wide-range input with reverse connection protection. It is the standard power supply of global automation control system.
