Voltage Monitor Relays

Plug-in

Voltage Monitor Relays monitor either AC single phase (50-60Hz) or DC voltages to protect equipment against voltage fault conditions. No separate supply (input) voltage is required on any Macromatic Voltage Monitor Relay. All versions are available in a compact plug-in case utilizing an 8 pin octal socket.

Macromatic offers Voltage Monitor Relays with two different functions:


Overvoltage/Undervoltage Relays - provide protection to equipment where either an over voltage or under voltage condition is potentially damaging. When used as an under voltage relay, they provide protection to equipment that is required to operate above a minimum voltage. When used as an over voltage relay, they protect equipment against excessive voltage conditions. Over/Under Voltage Relays are designed to operate when the operating voltage reaches a preset value and drop-out when the operating voltage drops to a level below the preset value.


Voltage Band Relays - provide protection to equipment that is required to operate within an upper & lower voltage limit. As long as the operating voltage remains within an OVER & UNDER voltage range, the internal relay stays energized. If the operating voltage falls outside this range, the relay will drop-out.
