WHAT ARE THEY?  They are line filters

WHAT'S THEIR USE? They are used to filter overvoltage transients on the main power line (400V, 500V or 690V. We're now working on a model with line voltage 1000V. This new product will be only mechanically similar, but quite different inside.

WHERE ARE THEY USED? They are mainly used aboard of high power converter cubicals. This is why a IP20 protection is enough, since the cubical structure will provide the needed extra protection against humidity, dust, moisture, etc.

WHOM CAN YOU SELL THEM TO? System integrators are your most likely targets. They are Companies that are designing power converters, usually outsourcing all they need (namely: the input transformer, the power converter, the cubical frame, fans, buss bars etc.). Most of the times they realize the line filter by themselves, assemblying the rectifying bridge, the power resistors, the caps, etc. The advantage of our solution is that it's a complete and proven circuit, that comes assembled in a user friendly IP20 enclosure

HOW MUCH PROVEN IS THIS CIRCUIT? Well, this circuit came after four years of extensive analysis of similar circuits used by the major converter manufacturers (ABB Drives, ASI Robicon, GE Drives, Toshiba El., Mitsubishi El., Siemens, just to mention some). We carried out this exercize with a Customer of ours, who's also acting as our beta site for new products in the fields of power assemblies for DC motor drives and electroplating

WHAT'S NEEDED TO DESIGN CORRECTLY THE RIGHT LINE FILTER? The driving design parameter is the maximum power of the input transformer. Just ask this value to your Customer, and we'll make the design for you, suggesting the right filter for their needs

WHAT ABOUT UL MARKING? All the plastic materials used for the North America markets are UL filed: wires, boxes, block terminal, etc.

DOES IT NEED A SPECIAL COOLING? Nope: natural convection is all you need. Just make sure to allow a sufficient air flow. The power dissipation occurs mostly just in case of line transient over-voltages (even if the filter has been designed for continuous operation, these occurrences are not so frequent in your Country. Canada is known to suffer worse line working conditions. Therefore you should enjoy a more interested audience over there, I guess.
