Transient Voltage Surge Suppression

PowerSure

DMK Series

Surge Suppression for AC Applications

The PowerSure

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 PowerSure

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

■ 3 year warranty

Emerson Network Power designs superior

Transient Voltage Surge Suppression (TVSS)

devices for a variety of field applications.

The PowerSure

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.
