Electronic Fusing System WAVEGUARD
|Weidmuller's WAVEGUARD Electronic Fusing System
dramatically enhances the reliability of an automation control panel.
|WAVEGUARD Electronic Fuses are used by connecting
them in series between a switch mode DC power supply and each of the loads in a
control panel. These electronic fuses constantly monitor the current delivered
to their assigned load and measure the delivery time, and when an overload or
short circuit current is detected, they open the load's circuit within
microseconds. The electronic fuse will isolate the failing circuit before the
DC power supply initiates a self-shutdown routine (most DC power supplies take
milliseconds to initiate the self-shutdown routine.) This ensures continued
delivery of power to the rest of the circuits in the automation control
|When either an overload or a short circuit
occurs, the WAVEGUARD Electronic Fuse will not only prevent the entire process
or machines dependent on the control panel from shutting down, but it will also
facilitate quick problem resolution by isolating the specific failure and
indicating which circuit has failed via fault contact and LED indication.
|WAVEGUARD Electronic Fuses offer a number of
advantages over melting fuses and conventional electromechanical circuit
|WAVEGUARD Electronic Fuses:
- Are transistor-based switching solutions that are
not affected by temperature changes. Operation points of melting fuses and
electromechanic circuit breakers are dependent on ambient temperature
- Provide remote monitoring and reset inputs to
reduce maintenance costs.
- Have local monitoring and electrical resetting
inputs so you can quickly troupleshoot to get the system up and running within
- Ride through peak in-rush current at system start
up to prevent nuisance tripping.
- Are DIN-rail mountable, and is available with an
adjustable rating of 0.5 to 5.0 Amps.
- Prevents a failure on a single load from shutting
down an entire panel or system.
- WAVEGUARD electronic fuses are connected in series
between the power supply and each of the loads.
- WAVEGUARD fuses can be remotely monitored and reset
for control panel troubleshooting.
