Introduction to tho three types based on their coil control methods: single-coil control, dual-coil control, and energy-saving board control (i.e., PWM control board + single-coil control). This article compares the structure, working principle, and energy consumption characteristics of DC contactors with single-coil, dual-coil, and PWM control methods, and analyzes their advantages, disadvantages, and applicability.
