This unit boasts an efficient switch mode technology that offers up to 96% typical efficiency.

Features

The R2S-1209 features a wide range of input and output voltage options (11-78 VDC) to meet a variety of needs. It provides continuous output power up to 500 W and peak output power up to 700 W for up to 10 seconds. It also features an integrated EMI filter, low, constant component stress, and a power-factor-corrected input. Additionally, it is designed to survive extreme shock and vibration, making it ideal for harsh and demanding operating environments.

Applications

The R2S-1209 is suitable for a wide variey of applications, including:

• Electronic equipment in harsh environments, such as military, transportation, and industrial applications
• UPSs, power distribution systems, mobile power systems, and building systems
• Generators, UPSs and, UPS systems, distributed supply systems, and EMI/RF systems

Working Principle

The unit works by taking the input AC voltage from a power source and converting it into a DC voltage. The output voltage is a sine wave with the frequency of the wave determined by the frequency of the input voltage. Both the amplitude and frequency can be adjusted to meet the application requirements. The unit then converts the DC voltage into a sine wave with an output frequency and amplitude that can be regulated and controlled. This process allows for efficient power delivery, effective EMI/RFI filtering, and robust built-in protection from input surges and output short circuits.

Protection and Monitoring

The unit provides both over-current protection and monitoring of the output voltage for a wide variety of applications, including process measurements, mobile systems, automotive systems, and distributed supply systems. It also features a smart input for short-circuit protection and over-voltage protection. Other features include temperature monitoring, fault alarms, and remote on/off control.

Conclusion

The R2S-1209 is a reliable, low-profile, fan-cooled, commercial off-the-shelf sine-wave DC-DC converter. It boasts a wide range of input and output voltage options to meet a variety of needs, and features an integrated EMI filter, low, constant component stress, and a power-factor-corrected input. Additionally, it provides over-current protection, monitoring, and temperature monitoring, as well as fault alarms and remote on/off control. With its efficient switch mode technology, it is an excellent choice for a variety of demanding applications.
