Aim-TTi CPX400DP Power Supply Twin 420W PowerFlex

Aim-TTi CPX400DP Power Supply Twin 420W PowerFlex


The Aim-TTi Twin CPX400DP is a different type of laboratory powersupply designed to meet the need for flexibility in the choice of voltage andcurrent. A conventional PSU has a fixed current limit giving a power capabilitythat reduces directly with the output voltage. The Aim-TTi Twin CPX400DPdesign enables higher currents to be generated at lower voltages within anoverall power limit envelope.
Each output can provide considerably highercurrent than a conventional PSU of the same maximum voltage and power (see powercurve). Example voltage and current combinations include 60V/7A, 42V/10A,28V/15A, and 20V/20A.

The PowerFlex regulation system used on the Aim-TTi Twin CPX400DPcombines a high frequency pre regulator with a linear post regulator to giveboth low noise and good transient response. Each output can operate in constantvoltage or constant current mode with automatic crossover and modeindication.

Separate voltage and current meters on each output give a resolution of 10mVand 10mA. The fixed resolution avoids the misinterpretation of readings that canoccur with auto ranging 3 or 3½ digit meters where the decimal point positionmoves as the reading changes. Coarse and fine voltage controls are provided. Thecurrent control is logarithmic enabling low current levels to be set accurately.A View Settings button enables limit settings to be checked and adjusted at anytime.

Each output incorporates remote sense terminals that can be enabled ordisabled at the flick of a switch. Remote sensing is essential for maintainingprecise regulation at the load and true metering of the loadvoltage.

Payments


We accept payment via PayPal or any credit/debit card (processed via Paypal).

All our listings include VAT at the current rate.

We dispatch orders Monday to Friday. Orders received on Weekends/Bank Holidays are dispatched next working day.

We aim to dispatch all orders requiring courier delivery on the same day as long as payment is received & the order is confirmed by 15:00.

We aim to dispatch all other orders that have been paid & confirmed before 16:00 on the same day.

Orders received after these times will be dispatched on the next working day.

Requests for courier delivery to UK addresses that involve a sea crossing are subject to a further charge, which we will contact you about if you place an order.

Any order placed using an unconfirmed PayPal delivery address may be subject to checking delays or cancellation.

For overseas orders of more than 1 item we can normally achieve a price of £1.00 per extra item in addition to the initial postage charge for the first item but this does depend on the weights of products ordered. If you make your purchase & then request a revised invoice we can adjust postage. If you are not happy with the charge the sale can be cancelled.

For full details please check our Terms and Conditions.

We pride ourselves on making sure each and every customer is satisfied before, during and after a sale is completed. If you have any questions about any of our items for sale or any order you have placed please send us an eBay message.

We have a dedicated team who monitor & respond to eBay messages 7 days a week.

Due to the large number of feedback we receive each day, we rely on eBay's automated system for leaving feedback on receipt of feedback left.

If you are considering leaving negative feedback or low detailed seller ratings please contact us before doing so to allow us to rectify your concerns & reason for leaving such feedback.

Unless stated all items are supplied with a 12 month return to base warranty.

If you change your mind about your purchase you may request a return for refund within 7 working days from receipt of your order.

If you receive an item that is incorrect or faulty on first use we will cover the cost of returning the product to us for replacement or refund.

If a product develops a fault in the warranty period please contact us for diagnostic help and returns if required.

All returns must be authorised before being sent back so that the return is received at the correct address and can be dealt with by our returns department in the the most efficient manner.

Please contact us by eBay messages to receive authorisation for all returns. During that process you will be issued with an RMA number.

Please ensure any item returned is sufficiently packaged as items damaged in transit not reported before return will invalidate your warranty.
