Medical Power Supply Challenges Solved and Time to Market Accelerated

Medical Power Supply Challenges Solved and Time to Market Accelerated

Product 

Normatec Pulse 2.0 & Normatec Pulse Pro 2.0 
Professional Grade Athlete Recovery System 

What We Did 

Armed with a power supply, components and filters our Engineering Manager drove from our facility in Hudson Massachusetts (USA) to meet Normatec at the EMC lab. First, we tried our standard power supply however this failed EMC. Upon a deep review of the frequencies in question, we realized that the noise was indeed not coming from the power supply but coming from the Normatec unit. Additional filtering was going to be needed, but there was no room in the Normatec equipment for any further filtering. 

Based on the frequencies and the attenuation needed, we changed the ferrite EMC filter on the power supply output cable, so that it would have the attenuation needed at those frequencies. We hand-built a unit while at the EMC lab in our commitment to get the job done. The test was repeated and received a solid pass with more than 6db of margin. We then re-tooled the ferrite EMC filter on the output cable which now had multiple turns on it, and we were able to solve the system level EMC issue.

Breas Medical Grade Power Adapter Solution

Breas Medical Grade Power Adapter Solution

The Challenge 

Provide a low cost, consumer-priced, AC/DC Medical Adapter for portable CPAP machine. 

How We Delivered 

The original power supply used by Breas was not ours. At the time we were contacted, it had about a 10% failure rate in the field. Not acceptable. We received the Z1 CPAP machine and immediately analyzed it in our lab. We found that when the person using the machine coughed into the mask, the CPAP device sent a voltage pulse back into the output of the power supply, thereby shutting it down. We implemented several modifications to our power supply which fixed the problem entirely, allowing Breas to ship problem-free product from then on, until today...and beyond.

Customised Power Supplies for CO2 Monitors

Customised Power Supplies for CO2 Monitors

Flamefast contacted TT Electronics with a high volume, time critical project to install their carbon dioxide monitors in schools, offices, and other populated indoor spaces to help reduce the spread of Covid-19. Initially over 50,000 power supplies were needed within 12-16 weeks to be installed in schools, in time for the start of the upcoming term. TT Electronics were selected as a partner for this project as we had previously supplied Flamefast with a reliable yet cost efficient power supply unit.

The Solution
We designed a solution without effecting existing safety approvals of the power supply which saved considerable engineering time and cost, enabling accelerated speed to market and confidence in the solution. TT Electronics supply a “modified standard” 5VDC Plugtop Adapter with bespoke output cables. Backed by our engineering & design support, we are able to offer a highly reliable power supply solution for a competitive price.
“We had previously taken other power supplies from TT Electronics, so made contact as we were struggling to find something on the open market to suit our requirements, and they could not have been more accommodating. As the monitors needed to be ‘easy to deploy’, we required a 2m cable whereas most of the available product are 1m or less. Not only were TT Electronics able to supply this, they were also able to provide this as a custom packaged solutions, as well as putting forward various sized mains adapters to allow the packaging for the Vision CO2 Monitors to be as compact as possible, in turn reducing assembly time and transport costs.”

MuReva Phototherapy System

MuReva Phototherapy System

Application

Photobiomodulation (PBM) offers a safe and effective treatment for Oral Mucositis with over 20 years of supporting clinical research. Unfortunately, limitations of current light-delivery technology had prevented its adoption sooner. MuReva’s new technology overcomes the current barriers and creates the first commercially viable, patient-friendly solution: the MuReva Phototherapy System.

The Challenge

  • Modified standard power supply that meets a challenging medical application
  • Specific requirements that could not be met by standard power supply
  • Specific EMC issues

The Solution

TT identified and offered a 24V, 65W medical-grade open frame power supply, providing Mureva with an OTS elegant solution that met or exceeded all system performance requirements, packaged within the solution’s architecture (open frame power supply), and complied with required safety standards. TT, and our local channel partner, provided ongoing technical support while managing very dynamic supply chain disruptions to mitigate schedule risk.
