WAVEGUARD is designed for use with switch mode power supplies. The technical characteristics of switched-mode power supply units mean that they either cannot supply a dynamic output current or can only do so within defined limits. They cannot reliably trip conventional circuit breakers and melting fuse. The WAVEGUARD electronic fuse was specially developed for this application. The electronic fuse is of course also suitable for all direct current applications.

Various rated currents The operating current is precisely adjustable between 0.5 … 8 A in the manufacturing process with a combination of resistors. There are 4 current ratings available as standard: 1.6 A, 3.15 A, 6.3 A and 8 A. Intermediate values can be realised at any time on request. Switching off and resetting with a switch

Connection The WAVEGUARD electronic fuse is connected into the positive branch of the circuit to be protected, like a conventional melting fuse or automatic circuit breaker. For power supply to the integrated electronics, the 0V potential must also be connected to the fuse.

The sliding switch integrated into the front is provided for switching the fuse element on and off. In the tripped state, the fuse can be switched on again with this switch provided the fault has been eliminated. Simply move the switch to “OFF”, wait 10 seconds, and switch on again. Additional reset input

Selective dynamic and static protection of 24 V DC circuits The electronic fuse consists of two fuse elements connected in series: a conventional melting fuse and an electronic fuse. This is realised with a rapidly responding solid-state switch. The circuit detects the current flowing through the fuse – when the current reaches the set maximum permissible value, the solid-state switch switches off within microseconds. The current flow is interrupted. This static value for maximum current is 100% of the fuse rating, but the fuse also has a dynamic component. That means it permits a higher current – similar to the tolerance factor of a conventional fuse – but only for a short time. After the dynamic phase, the electronic fuse is ready to trip at 100% of the rated current again. The values are selected to ensure that the upstream melting fuse does not trip.

For the purpose of remote reset, a voltage pulse can be applied to the reset input; the load circuit is closed with the falling flank of the pulse. Cyclic auto-reset is not permitted, nor is this advisable for safety reasons. Warning LED and potential-free signal contact Any fault that occurs must be signalled. An integrated LED and signal contact (NCC) indicate the switched state of the fuse. This helps to speed up troubleshooting and reduces repair costs.
