Mains power protection

ESP DC Series

Combined Type 2 and 3 tested protector (to BS EN 61643) for use on DC systems

to protect connected electronic equipment from transient overvoltages on the

mains supply, e.g. control equipment. Available for 12, 24, 36 and 48 V DC systems.

For use at boundaries LPZ 1 through to LPZ 3 to protect sensitive

electronic equipment.

Installation

Install in parallel, within the power distribution board or

directly on the supply feeding the equipment. At distribution

boards, the protector can be installed either on the load side

of the incoming isolator, or on the closest outgoing way to the

incoming supply. Connect, with very short connecting leads,

to positive, negative and earth.

Accessories

Weatherproof enclosure:

WBX 3
