  • The TPS002 can only support one KNA-VIS or KNA-IR controller and should not be used to power any additional units due to current limitations.
  • A KAP101 or KAP102 Adapter Plate is required to use a T-Cube with the KCH301 or KCH601.

We lost the Mini-DIN Connectors for TPS002, how can I get it in China? Thanks.

Hello, We bought the KPRM1E/M including the rotation stage and the motor driver. Now we cannot find the power supply and the USB cable of the KDC101 motor controller. I suppose we should buy a KPS101 as the power supply, but which one should I buy as the USB cable? Thank you. Yunwei

Response from Charles at Thorlabs: Hello and thank you for your query. Unfortunately the exact cables we send out (the locking USB 3.0 type) are not available on our site but we can provide a replacement. I will reach out to you about this. It may be helpful to know that it is actually possible to use these with any micro-USB 2.0 cable with no ill-effects.

P/S has no output (0V) after about 1 year in operation. Is it more likely to fail if it's plugged in all the time?

Response from Radu at Thorlabs: We are sorry to hear that your power supply had such a short lifetime. We aim to only sell high-quality power supplies with our devices, but failures can still occur. There are multiple mechanisms by which a supply can fail. Keeping them continuously plugged into the mains, even if the device is switched off or disconnected, can make some of these failure mechanisms more likely. This is due to an increased exposure to input voltage fluctuations and surge currents. Even with anti-surge protection circuitry in place, this still makes the internal ceramic capacitors more likely to crack and the semiconductor-based elements (diodes & switches) more likely to get damaged. With that being said, your supply is still under warranty. Therefore, I recommend that you contact your local technical support team and ask for a replacement.

Dear Sir or Madame, please specify the inner diameter of the connector (for TDC001) (inner: 1.3 or 1.45 mm; outer: 3.5mm). Thank you with best regards, Jörg Neuhaus

Response from Jeremy at Thorlabs: The barrel size is 1.3mm.

I did not see that the TPS002 power supply that we ordered is not compatible with our T-cubes for LEDD1 (actually this is not very logical because you sell TPS001 and TPS008 compatible, but not TPS002, this should be made clearer on your website because there is a denomination"T-cube" for all the T-cubes TDC001, TST001, LEDD1, TSC001 etc, although they are very different...)

  • Individual Power Supplies for One K-Cube or T-Cube
    • KPS201: For K-Cubes or T-Cubes with 3.5 mm Jacks
  • Power Supply for up to Two K-Cubes or T-Cubes
    • TPS002: For K-Cubes or T-Cubes with Mini-DIN Input

The KPS201 offers a simple power supply for select individual K-Cubes or T-Cubes, while the TPS002 supplies power for one or two select K-Cubes or T-Cubes. Please refer to the compatibility information in the list or table above. The TPS002 can only support one KNA-VIS or KNA-IR controller and should not be used to power any additional units due to potentially exceeding the current limit.

The cubes need to be hooked up individually to a computer via a USB cable to use them with the motion control software. One region-specific plug adapter, selectable at checkout, is included with each power supply. The adapter plugs for the KPS201 are shown to the right.

  • USB Controller Hubs for up to Three or Six K-Cubes or
  • Provide Power and Communication with a Single USB Cable and a Single Power Connection
  • Adapter Plate Connects T-Cube to Hub

These USB Controller Hubs have been designed specifically with multiple K-Cube and T-Cube operation in mind. The hub vastly reduces the number of USB and power cables required when operating multiple K-Cubes or T-Cubes. Furthermore, a USB output connector can be connected to the USB input on another unit, allowing multiple Controller Hubs to be connected together while still only using a single USB cable from the host control PC.

The hub draws a maximum current of 10 A; please verify that the cubes being used do not require a total current of more than 10 A.

The KCH301 and KCH601 Controller Hubs are compatible with all K-Cube and T-Cube modules. A KAP101 or KAP102 Adapter Plate (sold separately) is required for each T-Cube to operate on the controller hub. The KAP101 is designed to adapt 60 mm wide T-Cubes to the hubs, while the KAP102 is designed to adapt 120 mm wide T-Cubes to the hubs.

For more information on the USB Controller Hubs, see the full web presentation.
