Every developer looks forward to the moment when he knows that his prototype is finally working, all key functions have been realized and the software is fully implemented except for the diagnostic functions. At the next meeting, he proudly announces that all that is needed at this stage is the EMC approval and a suitable power supply. 

However, given the limited resources, designing a power supply in-house is not an option, as crucial deadlines would be missed. The team thus agrees to go for a third-party product, and the developer starts looking for a power supply. Although there is no shortage of such products in the market, identifying the right components proves often more tricky than first thought.

RACM1200-V from RECOM

RACM1200-V was designed with this adage in mind and comes with all the necessary approval certificates

In the example, the product must conform to standard X, protection class Y, and even 2MOPP, as it has been decided that the power supply is also to be used in a recently launched ventilator. On top of all, the developer also needs to consider the MTBF rate. Just imagine a patient connected to a ventilator – and the power supply suddenly fails. This must of course be prevented at all cost! So, the developer needs to know how long a power supply works safely without maintenance. This article about the RACM1200-V from RECOM answers some of these questions.

RECOM believes that the safest option is the only option, and the RACM1200-V has been designed with this adage in mind and comes with all the necessary approval certificates.

New standards for RACM1200-V

The RACM1200-V is setting new standards for compactness and covers a wide power range for reliable fan-less operation. A special base plate ensures effective heat dissipation for up to 1000 W continuous output power. The RACM1200-V comes with two additional outputs so that there is no need for additional power supplies as would otherwise be the case for certain applications. It features an adjustable 12 V system fan output and a 5 V/1A standby output.

RECOM thus offers designers of such units a power supply that meets their specifications

Thanks to the high insulation strength of 4 kVAC between the mains voltage and the output voltages, the RACM1200-V can be used in virtually all areas where a power supply is required, such as chargers, LED lighting systems, laser equipment, analytical instruments, high-frequency devices, robots, medical beds, and chairs as well as medical-technical devices with direct patient contact. RECOM thus offers designers of such units a power supply that meets their specifications.

Patient safety standards

While the RACM1200-V is certified according to IEC 60601-1, it does of course not guarantee that the device into which it is to be integrated also meets this standard. However, using a certified power supply is one of the preconditions for compliance, and certainly speeds up the certification process for the end product, let alone reduce development costs.

The signal outputs and the 5 V output come with 1.5 kVAC insulation to the mains voltage

The RACM1200-V provides certified 2MOPP (MOPP = Means of Patient Protection) insulation and minimum leakage current, which means that it conforms to the patient safety standards that apply to medical technical equipment. The signal outputs and the 5 V output come with 1.5 kVAC insulation to the mains voltage.

Features of RACM1200-V series 

The RACM1200-V series features an integrated EMC filter that easily meets the requirements of EN 55032:2015 Class B for radiated and line-bound interference. The new RECOM power supply conforms to all relevant international safety standards for industrial applications, IT products, and medical technical equipment.

The input voltage range is 85 VAC to 264 VAC. The RACM1200-V allows for up to 1000 W continuous output. It features a 40mm high metal housing with contact cooling and a footprint of only 102 mm x 229 mm. For up to 10 seconds, the output power might even be 1200 W. For 1200W continuous output, the power supply must however be equipped with a fan that ensures and air flow of 2.5 m/s through the unit. That is why the RACM1200-V is fitted with a controllable auxiliary output for temperature management.
