OVERVOLTAGES – MF/AF HARMONICS

MULTI-STAGE SURGE PROTECTIVE DEVICES AND MEDIUM AND HIGH FREQUENCY HARMONICS

UNIFIED PROTECTIVE DEVICES – SPU

Unified Protective Devices- SPU, are made up of multiple and redundant surge protective devices coordinated to each other and conceived under the criteria of maximum discharge capacity and medium residual voltage.
Its design allows the implementation of accessory modules, as well as to be adapted to the needs of each installation and giving preference to safety and its proper functioning.

SPU devices have been conceived to ensure installations are protected against overvoltages, either atmospheric or industrial origin, MF/AF harmonics and peaks associated to microinterruptions. Optionally, the electrical installation will be protected against surges, power interruptions and phase asymetry effects by adding a PTR4 set. This set is time and voltage programmable.

The main features of SPU protective devices are:

High discharge capacity in 8/20 and 10/350μs waveforms.

Residual values close to nominal voltage of the installation to be protected.

Frequency filtering.

 Between 3 or 4 different  protective sets effective and coordinated by themselves are available.

 Phase-earth, phase-neutral and neutral-earth overvoltages erasing.

 Typical response time, 0.025μs.

Micro-interruptions erase in low power installations.

Repairable.

PROTECTIVE DEVICES WITH VOLTAGE STABILIZATION – SPE

Unified Protective Devices with voltage Etabilization- SPE, consist on several protective sets coordinated with each other to avoid voltage electrical disturbances. Its design allow its adaptation to the needs of each installation giving preference to safety and proper operation.

These protective devices ensure the proper functioning of installations against permanent overvoltages, undervoltages, transient overvoltages (8/20us), MF / AF harmonics and peaks associated to micro-interruptions.
It is highly recommended to install SPE devices in installations with undervoltage problems and poor power supply, as well as in installations where it is essenteial to enesure the perfect operation of critical loads and/or sensitive electrical and electronic devices.

The main features of SPE protective devices are:

Electrical protection against atmospheric discharges.

Electrical protection against industrial overvoltages.

Protection against permanent overvoltages.

MF/AF harmonics filtering.

 Protecction against overvoltages and undervoltages.

Output voltage stabilization ± 2% (Vin ± 25%).

Independent regulation by phase (± 1% ~ ± 5% ajustable)

With and without galvanic isolation transformer.

Power rates up to 3.000 KVAs.

PROTECTIVE DEVICES WITH VOLTAGE STABILIZATION – SDK

SDK protective devices have been designed to protect High Voltage installations when they can not be protected in Low Voltage due to acces impossibilities and lack of space.

SDK series devices have been conceived under criteria of maximum discharge capacity and minimum residual voltage.

Due to residual voltage of the devices of SDK series which is adjusted to the maximum voltage of the installation to be protected, its high discharge capacity as well as differential protection- protection between active conductors, in case of lightning strikes, voltage peaks associated to micro-interruptions, start and stop proccess of engines or any type of transient overvoltage, our protective devices avoid frank and latent breakdowns in all electrical and electronic devices.

The main features of SDK protective devices are:

Great discharge capacity in 8/20 and 10/350μs waveforms.

Residual values close to the voltage of the installation to protect.

Common and differential mode overvoltages are eliminated.

Response time 0,025 μs.

Repairable.

Remote signiling in case of failure.

Devices of SDK series are adjustable to any kind of installation.
