DMK Series
Surge Suppression for AC Applications
The DMK Series of Transient Voltage Surge Suppressors (TVSS) provides fast, reliable protection
for AC circuits. A small footprint allows easy installation in almost any environment. Install at
your critical distribution panel to protect all down-line equipment.
The DMK Series features independent primary Silicon Avalanche Diode (SAD) and secondary
Metal Oxide Varistor (MOV) suppression technology to ensure continued protection. The latest
technological advancement of the DMK Series is the addition of V3 SHIELD™ Technology, which
provides the lowest-possible clamp voltage to peak pulse current handling far in excess of
traditional fused designs. Combined with a solid grounding system, the DMK Series is the
ultimate in protecting sensitive electronic equipment from damaging transient voltage surges.
Features
■
■
Nondegrading Bipolar SAD technology
provides reliable performance with the
lowest-possible clamping voltage and fastest
response time in comparison to other
TVSS technologies
V3 SHIELD™ Technology provides thermal
protection against prolonged over-voltage
conditions
■
V3 SHIELD™ Technology allows actual
peak pulse current to be handled by the
suppression module, well in excess to
traditional fused modules
■
Status indication on each module to show
normal compromised suppression status
■
Field replaceable modules for easy repair
and upgrade
■
Independent primary SAD suppression and
secondary MOV suppression technology ensures
continued protection
■
Remote failure indication for long
distance monitoring
■
Interior and exterior enclosures available
Emerson Network Power designs superior Transient Voltage Surge Suppression (TVSS) devices for
a variety of field applications. The DMK Series is available with various configurations and
energy-handling ratings to ensure the proper level of protection for your application. As part of the
total power protection solution, Emerson Network Power provides engineering assistance to
configure the appropriate equipment for your individual needs.
