Wide product lineup for
various DC controls

The trend toward higher capacities and voltages in battery-based devices, like storage batteries and energy systems, aims to extend operating time and reduce charging time. Suitable relays for each application are in demand.
OMRON offers a diverse lineup of DC switching relays for inrush current protection and power switching applications in inverter circuits.

“Higher capacities and higher voltages” trend to increase in
battery-based power supply systems.

Advantage of higher capacities

Increased equipment capabilities and longer operating times,
but longer charging times

Operating time 1 hour => Operating time 10 hour

Advantage of higher voltages

Reduced charging time because a lot of power can be sent for charging even with higher capacities

Charging time 5 hour => Charging time 1 hour

As “higher capacities and higher voltages” increase heat generation, it is also necessary to have current-carrying and current-breaking capabilities to further ensure safety.

OMRON meets various needs with its technology to suppress heat generation and optimal current-carrying and current-breaking capability design.

OMRON offers a wide range of DC switching relays compatible with various devices, meeting the demand for higher capacities and voltages while maintaining similar performance in voltage, current, size, and mounting method.

Please consult your OMRON dealer when ordering DC switching relays.

Note: The values shown indicate the maximum voltage and current values.
