Time delay undervoltage module
The Time Delay Undervoltage module (see
Figure 71
)
takes an AC input voltage, rectifies it via a diode bridge
to provide a DC output.The function of this remotely
mounted device is to pass through its available voltage to
the circuit breaker mounted Undervoltage Release (UVR)
accessory. Also, on the loss of voltage or during a low
voltage condition, it will assert the energy of a storage
capacitor to provide a temporary voltage for the duration
of up to two seconds. The Time Delay settings are user
selected via a jumper that bridges selected pins together.
When the line voltage is available to the module, the
green, Power On, LED is illuminated. The module is setup
for DIN Rail mounting.
