DRS (DC) Series
DIN Rail Protection
The Edco
™
DRS (DC) Series is a DIN rail mountable, single-pair surge suppression
module implementing three-stage hybrid technology. This module addresses
over-voltage transients with gas tubes and silicon avalanche components. In
addition, sneak currents are mitigated with resettable fuses (PTCs). The PTCs
increase resistance several orders of magnitude when over-currents exceed
safe levels. A normal state resumes when over-currents are removed. The ability
to self-restore in this manner significantly increases suppressor performance
and survivability.
The Edco
™
DRS (DC) Series mounts onto a standard 35 mm industrial DIN rail. There
are three “Field Side” and three “Electronics Side” screw terminals. One is reserved
for a shield. Three electrically tied ground terminals are provided for grounding the
Edco
™
DRS Series unit to Building-Approved Ground. Shield is isolated from ground.
For a 2-terminal version without a shield, order the Edco
™
DRS-XXX-2.

**Warning!! DRS-130RMS is for Discrete Signal
Use Only. Do not use DRS-130RMS on 120
VAC Power Lines. This unit is a non-hybrid,
MOV design, rated above 5 A operational
current and can withstand greater than eight
occurrences of a 10 kA 8 x 20 µs waveform, and
greater than 1000 occurrences of a 200 A 10 x
1000 µs waveform.
