What is a DC power relay?

A DC power relay is a relay that uses a DC power supply to send a contact output. General relays use an AC power supply, but when using a DC power supply, a special design such as connecting a diode is required. Widely used in industrial fields dealing with high voltage and high current. DC power relays are essential equipment in many fields that use DC power. Demand is increasing in fields requiring high reliability.

Application of DC power relay

✅Automotive Applications
Used in EVs (electric vehicles) and hybrid cars to control high-current battery systems.
Applied in switching electrical components such as headlights, fan motors, and power seats.
✅ Industrial Machinery
Used in factory robots and automation systems for DC power switching.
Also utilized in solar panels and battery system power control.
✅ Telecommunication Equipment
Applied in UPS (Uninterruptible Power Supply) systems and base stations for power management.
Controls high-current power switching with low-voltage control signals.
✅ Railway & Transportation
Used in electric railway systems and signal control for DC power management.
Helps manage power in automatic ticket gates and station lighting systems.
