EDS1 Series DC Isolator

Product Application
EDS1 series isolation switch is suitable for a power system with rated voltage up to
DC1200V and rated current up to 32A . The product can be used for infrequent
switching-on and switching-off and can disconnect 1 ~ 4 MPPT lines at the same time.
It is especially suitable for isolating lines in HVDC transmission and distribution systems,
such as cutting off the high voltage direct current between solar panels and inverters.

Product Benefits
Installed at any angle can achieve IP66 waterproof level
UV resistance and V0 flame retardant material
Contact Silver Plating, silver layer thickness to the industry’s highest standards
Arcing Time in 1ms
Vent valve at the bottom of the external box
No Polarity
Lockable at OFF position
AS 60947.3 and IEC 60947.1standard
Provide 5-year warranty product guarantee.

Aluminum box
Metal material, with anti-corrosion, anti-explosion resistance against IK10,
can adapt to harsh environments
