Description
Overview
The 3.5” TFT full-colour screen displays measured values and enables control and optimisation of the power electronic devices, systems and industrial installations. The meter provides measurement of 54 parameters and harmonics up to 63rd. A RS485 port or Ethernet interface provides transmission of all parameters to a master system. Three relay outputs signal the overflow of the chosen value and the programmable analogue output maps the assigned parameter. The temperature inputs can be used to control the temperature of the transformers windings, motors etc.
Features

No problem, our qualified engineers are here ready to answer your call, fax or email. If you like to browse the information first, we have all product information on-line plus useful calculation & product selection tools to help you select the right product. And all accessible 24/7 without the need for passwords or any form filling.
If the item is not in stock then we will normally guarantee the goods delivered within 7 days if required. This may depend on the quantity and size (if thyristors) but for quantities of 20 or less, then this should never be a problem.
We’ve made this as easy and accessible as we can. As the Internet is open 24/7 we have loaded as much relevant product data onto our web site and in a clear concise manner, so you don’t waste unnecessary time. Data includes quick-look guides for wiring / dimensions / start-up, product features & comparisons, selection tools, product data sheets, full installation & operating manuals plus press releases & application notes.
We know from experience that next year the order of 2 may be 500. Our relationship with our clients, big or small, is never taken lightly. See our Company Mission Statement, it’s who we are.
We understand that speed is important in business and as long as you accept that the accuracy of the quote is proportional to the amount of data given, we’ll provide a quote any which way you like (typically over the tel, via fax or email, or in person).
We do not differentiate a telephone enquiry to an email enquiry. The same level of importance is applied to both. You will always receive an email to confirm receipt and a guaranteed personal reply within 20 minutes (within normal working hours).
We offer delivery based on the urgency and size/weight of the goods that match your expectations. From just £6.50 for next day courier, we can offer before 9am, before 12, anytime next day plus two day courier services within the UK.
We only charge the true carriage cost plus any additional package material to get it safely to you. We do not believe its right to charge you any additional admin or labour packing costs, anymore than if we charged you for answering the telephone. And it’s always our responsibility until you sign & receive the goods.
If it’s legal then we can accept it. We operate favourable credit accounts, payment by credit card via the web site or over the phone, cheque or cash payments, in Sterling or Euros.
