TMR-9WI Series

Product catalog summary

Overview: The TMR 9WI Series is a family of 9W isolated DC/DC converter modules designed for high power density applications. These converters feature a wide 4:1 input voltage range and are available in a compact SIP-8 metal package, with an optional plastic casing.

Key Features:

Ultra-wide input voltage range (4:1)
High efficiency up to 89%
Operating temperature range from -40°C to +85°C
Indefinite short-circuit protection
I/O isolation of 1600 VDC
Remote On/Off control
RoHS compliant with a 3-year warranty

Specifications:

Input: Current at no load is 9 mA for 24V models and 3 mA for 48V models. Surge voltage is 50V max for 24V models and 100V max for 48V models.
Output: Voltage set accuracy is ±1% max. Ripple and noise are 50 mVpk-pk for 3.3, 5, and 9 VDC models, and 75 mVpk-pk for 12, 15, and 24 VDC models.
General: Operating temperature range is -40°C to +85°C, with a case temperature max of +105°C. The converters have a reliability MTBF of over 2.9 million hours.

Models and Efficiency: The series includes various models with different output voltages and efficiencies ranging from 82% to 89%. For example, the TMR 9-2410WI model provides 3.3 VDC output with 82% efficiency, while the TMR 9-2415WI offers 24 VDC output with 89% efficiency.

Compliance and Safety: The converters comply with safety standards IEC/EN 60950-1 and UL 60950-1, and are designed for operation at altitudes up to 5000 meters. They are also environmentally compliant with RoHS and REACH directives.

Physical Specifications: The converters are housed in a copper casing (plastic for option -P) with a weight of 5.9 g for the metal package and 4.8 g for the plastic option. Dimensions and pin configurations are provided for both single and dual output models.
