Shipping info

Reclaim your unused watts!
Did you know that typical 5V adapters draw 240% of the actual wattage they deliver, with 140% being wasted as heat? Moreover they take it from your precious 12V rail.

Beating even other switching-supply adapters, the NoDrain converter takes its power where there is plenty unused: the 12V negative rail! You can safely assume that the current taken on the 5V is always divided by two to know the current taken on the -12V rail.

The NoDrain adapter does its conversion with high efficiency.
With 1 amp available, you can distribute the 5V from the NoDrain to several busboards.
Thanks to ultra high-speed switching technique there is no noise to be heard.

Just plug a NoDrain in one of the connectors at the back of your rack and you’re done.

Features

  • Offers up to one amp of precise 5Volts
  • Takes its power from where you won’t use it: the negative rail
  • Gives you back the +12V power previously used to make 5V
  • High efficiency conversion: Every milliamp delivered on the 5V rail only draws around half as much milliamps on the -12V rail
  • Soft-start prevents current inrush at power-on
  • Tolerates wide voltage variations of the -12V source
  • Miniature module 20x28mm - 0.78x1.10"
  • Adjustable output voltage - delivered calibrated
  • Protected against:
    • Current overload
    • Input overvoltage
    • Overheating
    • Short-circuit
    • Reverse insertion

How much is my shipping?

Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK it's normally around £4 for order values under £150, and free above that. Shipping to mainland EU is typically between £7 and £20, depending on the shipping method and the size and weight of the order.

Do you ship to my country?

Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.

Shipping methods

We use a combination of Parcelforce, DPD, Royal Mail and UPS for the UK, and for international orders it's either Royal Mail, UPS, DHL or FedEx depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.

Dispatch times

For UK orders, we normally dispatch the same working day if we get the order before 15:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.

For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes FedEx or UPS may come a little earlier than scheduled which would also push an order into the next day.

Shipping times

Since April 2020 the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer.

There is absolutely nothing we can do about this unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.

Saturday shipping

If you're in the UK and you order before 15:30 on a Friday then we can send something for a Saturday delivery (NB: this applies to UK mainland addresses only). The success rate with DPD is about 95% so it's worth a punt most of the time. Please note that if you select Saturday shipping on an order placed earlier in the week, we'll wait until Friday to ship it.

Pre-orders

If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.

If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch if you have questions.
