The TMR 9-4821 is an isolated DC/DC converter module from Traco Power's TMR 9 series. It provides dual regulated outputs: +5V at 800mA and -5V at 800mA, with a total output power of 8W. The converter operates over a wide input voltage range of 36-75V (48V nominal) and features a typical efficiency of 86%.
The module includes remote on/off control and indefinite short circuit protection. It offers 1600VDC input/output isolation, making it suitable for applications requiring galvanic isolation. Output voltage set accuracy is ±1%, with line regulation of 0.2% and load regulation of 1%.
Housed in an ultra-compact 8-SIP plastic package with 6 leads, the TMR 9-4821 measures 21.8mm x 9.6mm x 11.2mm. It is designed for through-hole mounting and operates over a temperature range of -40°C to +85°C (with derating). The converter is fully RoHS compliant and intended for ITE (commercial) applications such as communication equipment, instrumentation, and industrial electronics.
