SSAC KVM Series Data Sheet
KVM SeriesVoltage Monitors
TP = Undervoltage Setpoint
R = Reset Point
The KVM Series is a single-phase undervoltage
monitor designed to protect sensitive equipment
against brownout undervoltage conditions. The
compact design and encapsulated construction
make the KVM an excellent choice for OEM
equipment.
For more information see:
Appendix B, page 165, Figure 1 for dimensional drawing.
Appendix C, page 169, Figure 16 for connection diagram.
Operation
The output relay is energized and the LED glows
green when the input voltage is above the reset
voltage threshold. If the input voltage drops below the
undervoltage setpoint, the output relay and LED will
de-energize. The output relay will remain de-energized
as long as the input voltage is below the reset voltage.
Reset is automatic when the input voltage returns to a
normal range.
Features:
• Economical single-phase brownout/
undervoltage protection
• Isolated, 8A, SPDT output contacts
• Protects sensitive 110 to 120VAC or 220
to 240VAC loads
• Adjustable low voltage trip point
• LED Indicator
