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.

In industrial control cabinets where reliable low-voltage DC is critical, the MEAN WELL NSD10-12S5 steps in as a compact DIN rail power supply. It converts a 12V DC input (9–18V range) to a regulated 5V DC output at up to 2A, delivering 10W for sensors, controllers, and small automation devices.

Key specifications

  • Input voltage: 12V DC nominal (9–18V DC range)
  • Output voltage: 5V DC
  • Output current: 2A
  • Output power: 10W
  • Efficiency: 85%
  • Isolation voltage: 1500V DC
  • Mounting: DIN rail
  • Operating temperature: -20°C to +70°C
  • Protections: short circuit, overload, over voltage
  • Ripple & noise: 50mVp-p
  • Line regulation: ±0.5%
  • Load regulation: ±1.0%
  • Cooling: free air convection
  • MTBF: >1,000,000 hours
  • Compliance: UL60950-1, TUV EN60950-1, CE
  • Connectors: screw terminals (input and output)

Why choose it

The NSD10-12S5 offers robust isolation and full protection features in a space-saving DIN rail housing. Its wide input range handles fluctuating DC sources, while the regulated 5V output ensures stable power for sensitive electronics. With high efficiency and convection cooling, it runs quietly without fans, reducing maintenance and downtime.

Ideal use cases

  • Industrial automation and control systems
  • Powering sensors, relays, and small PLCs
  • DC-DC conversion in vehicles or battery-powered equipment
  • Building automation and HVAC controllers

Good to know

The NSD10-12S5 is a DC-DC converter, not an AC-DC power supply. It requires a 12V DC source (e.g., battery or another power supply). Screw terminals simplify wiring in field installations. Its MTBF of over 1 million hours reflects long-term reliability under normal operating conditions.
