TRACOPOWER TDR 3WISM Dual Output Regulated Isolated DC/DC Converter 12V dc, 125 mA, 18V dc Input, 3 W Surface TDR 3-1222WISM

TRACOPOWER TDR 3-1222WISM is a precision engineered dual output DC/DC converter offering regulated isolated power conversion with a maximum output power of 3 watts. It features a wide 4:1 input voltage range from 4.5 V to 18 V dc, supporting diverse DC supply conditions. The converter is designed as a surface mount device with a compact footprint of 18.9 mm length and 8.7 mm depth, enabling easy PCB integration.

This module provides two isolated outputs, including a positive 12 V dc at 125 mA and a corresponding negative 12 V dc output, ideal for powering analog and digital circuitry requiring dual polarities. Electrical isolation of 1500 V dc is maintained to protect system components and reduce noise interference in sensitive electronics.

Key features include continuous short circuit protection, low output ripple and noise, and a high efficiency of approximately 82%, helping to reduce thermal dissipation and improve system reliability. The converter supports a wide operating temperature range from -40 °C to +85 °C, making it suitable for demanding industrial and communication equipment environments.

The device is qualified for lead-free soldering processes as per IPC J-STD-020 and complies with RoHS environmental standards. Remote On/Off control adds system flexibility for dynamic power management.

Typical applications include industrial electronics, instrumentation, and communication devices requiring isolated and regulated dual supply voltages in compact, surface mount format.
