Main features and advantages

The 500ITM02 1MRB150021RO116 uses the third generation resonant conversion technology to significantly reduce electromagnetic interference (EMI<55dBμV) and ensure the stability of the power supply of sensitive equipment through dynamic load adjustment rate (±0.5%). Its intelligent parallel function supports the redundancy of up to 6 modules in parallel, seamlessly switching to the standby unit in case of a single failure, and the system availability reaches 99.999%. The front-end of the module is equipped with a detachable filter unit, which is compatible with the three-phase unbalanced power grid environment and can effectively suppress harmonic interference.
To adapt to the harsh environment, the module housing is made of high-strength aluminum alloy and anti-corrosion coating, and the key components inside have passed 2,000 hours of salt spray testing. The fan speed regulation strategy is based on the dual feedback of load and temperature, the noise is less than 45dB (A), and the standby power consumption is less than 1W in energy-saving mode. In addition, Emerson’s proprietary Predictive Health algorithm reduces the risk of unplanned outages by predictive maintenance that prompts key parameters such as capacitor aging and fan life.
