We want to increase power generation efficiency

Development / Design Environmental Response
“Miniaturization” and “low heat generation” hold the key to the spread of clean energy

In order to respond to the risk of climate change caused by global warming, there is a growing movement worldwide to accelerate the spread of clean energy.
For the spread of clean energy, it is necessary to improve power generation efficiency by increasing the capacity. However, this entails an increase in the amount of heat generated.
This results in larger equipment and higher costs due to the introduction of cooling mechanisms, hindering widespread use.
OMRON supports the spread of clean energy by providing products that enables “miniaturization” and “low heat generation” while responding to higher capacities.

DMS GREEN PROJECT

OMRON proposes power relays that contribute to “miniaturization” and “low heat generation” while responding to higher capacities.

01 Miniaturization realized by bidirectional power interruption

Storage battery

Realizes miniaturization by reducing the number of parts

Four conventional 400 VDC relays are used

600V charge, 600V discharge (Approx.75% reduction in mounting area)

G9KB
Supported by one 600 VDC relay (50A)

600V charge, 600V discharge

Bidirectional charging and discharging switching is possible.

G7L-X-SI [NEW]
Supported by one 600 VDC relay (30 A)

600Vcharge、600Vdischange

Bidirectional charging / discharging switching is possible. Breaking all lines is also possible with a single relay.
