Surge protection for DC power supply

As new players in the strong OBO team against surge voltages, the V20 and V50 DC arresters guarantee reliable surge protection for DC power supplies. Their high-performance varistor technology guarantees a follow current interrupt rating of 25 kA. The arresters are ideally suited for use in the field of 5G expansion.

They have a very low-voltage protection level and can be used up to lightning protection Class III. The arresters have a remote signalling contact and, with a width of just 1 part unit (18 mm), are real space-savers.

The variants at a glance:

• Type 2 arrester for 48 V DC (60 V DC max. continuous operating voltage)
• Type 1+2 arrester for 48 V DC (60 V DC max. continuous operating voltage)
• Type 2 arrester with 20 kA I_n
• Type 1+2 arrester with 12.5 kA I_imp
