DescRiPtion
The 587B Series of 120 Volt AC Surge Suppressors is designed for use by the OEM, equipment installer and or mainte-
nance contractor. These modules employ a three stage technology proven to be the most cost effective and reliable
method in protecting sensitive electronic equipment from over voltage transients. This series is designed to protect AC
powered equipment from the 6,000 volt peak open circuit voltage and 3,000 Amp short circuit current as defined in
ANSI/IEEE C62.41, Category C1.
The 587B Series offers a high degree of protection against 120 VAC EMI line noise. It is ideal for protecting 400 Volt
components because the solid state TVS technology assures that the line-to-neutral voltage will not exceed 400
Volts. While the modules are designed for transient voltage protection, the advanced circuitry will also attenuate the
amplitude and slow the rate of rise of high frequency noise acting as an EMI filter. The 587B Series includes differen-
tial mode protection, which is effective in reducing interference from line to equipment and are effective in reducing
equipment generated noise to meet FCC, VDE and CSA interference requirements.

Figures 1 and 2 are photographs of digitized waveforms showing the typical clamping action of a 16A module. A 12 Ohm resistor is used to repre-
sent a 10A equipment load. The load is then subjected to the ANSI/IEEE C62.41 Catagory CI test conditions (6000V/3000A). These photographes
contrast the effect on equipment with and without the protector.
