TVM規(guī)格書(shū)詳情
Description
The TVM Series Provides protection for motors and other
sensitive loads. Continuously measures the voltage of each
of the three phases using a microcomputer circuit design
that senses under and overvoltage, voltage unbalance, phase
loss, and phase reversal. Protection is provided even when
regenerated voltages are present. Includes a trip delay to
prevent nuisance tripping and a restart delay to prevent short
cycling after a momentary power outage.
Operation
Upon application of line voltage, the restart delay begins.
The output relay is de-energized during restart delay. Under
normal conditions, the output energizes after restart delay.
Undervoltage, overvoltage, and voltage unbalance must be
sensed for continuous trip delay period before the output is
de-energized. The output will not de-energize if a fault is
corrected during the trip delay. The restart delay begins as
soon as the output relay de-energizes. If the restart delay is
completed when the fault is corrected, the output relay will
energize immediately.
The output relay will not energize if a fault or phase reversal is
sensed as 3-phase input voltage is applied.
Reset: Reset is automatic upon correction of a fault.
LED Operation
The LED flashes green during the restart delay, then glows
green when the output energizes. It flashes red during the trip
delay then glows red when the output de-energizes. It flashes
red/green if phase reversal is sensed.
