Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

Shipping & Returns

The MEAN WELL SPAN02B-05 is a compact DC-DC converter designed for PCB mounting in a SIP through-hole package. It accepts an input voltage range of 18–36 VDC and provides a regulated single output of 5 VDC at up to 0.4 A (2 W total). The module is RoHS compliant and intended for use in small electronic devices and embedded systems where a stable 5 V supply is required from a higher DC bus.

Advantages

The SPAN02B-05 offers a small footprint and a through-hole SIP package suitable for reliable PCB connections. Its wide input range (18–36 V) allows compatibility with various DC supply sources. The fixed 5 V output at 0.4 A provides a simple solution for powering logic circuits, sensors, and control electronics without additional regulation. RoHS compliance ensures it meets common environmental and assembly standards.

Suitable for

  • Embedded systems and microcontroller boards requiring 5 V from a higher DC voltage
  • Industrial control modules with 18–36 V supply rails
  • Sensor interfaces and low-power peripherals
  • Prototyping and PCB-mounted power solutions

Key specifications

  • Manufacturer: MEAN WELL
  • Model (MPN): SPAN02B-05
  • Input voltage: 18–36 VDC
  • Output: 5 VDC, 0.4 A (2 W)
  • Package: SIP through-hole PCB mount
  • Compliance: RoHS
  • EAN: 4021087041102

How to use

Mount the SIP through-hole pins into the PCB and solder according to good soldering practice, observing polarity for input and output connections. Provide an input DC supply within the specified 18–36 V range. Connect the 5 V output to the target circuit, ensuring the load does not exceed 0.4 A. Allow for appropriate PCB copper area or heatsinking if operating near maximum load to maintain stable temperature and performance.

Recommendations

Use appropriate input filtering and a fuse on the input rail for protection. Verify input and output polarity before powering the board. For critical applications, test the converter under expected temperature and load conditions to confirm it meets system requirements.
