TRN 1-4823SM

Product Overview

The TRN 1-4823SM from Traco Power is an isolated module DC-DC converter for board-mount power conversion. It accepts a 36 V to 75 V input and provides two outputs, +15 V and -15 V, each rated at 35 mA, for a total output power of 1.1 W. The surface-mount 7-SMD module measures 11.9 mm x 11.3 mm x 8.0 mm and has 1.6 kV voltage isolation. It operates from -40°C to 90°C, achieves 79% efficiency, and includes an SCP feature.

Key Features

• Isolated module with 1.6 kV voltage isolation
• Dual outputs: +15 V at 35 mA and -15 V at 35 mA
• Wide input range: 36 V to 75 V
• 1.1 W total output power and 79% efficiency
• Surface-mount 7-SMD module, 11.9 mm x 11.3 mm x 8.0 mm, operating from -40°C to 90°C
• Includes SCP feature

Applications

• Commercial instrumentation and test equipment needing isolated dual-rail power for low-current circuits
• Board-level designs requiring 1.6 kV voltage isolation in compact surface-mount layouts
• Devices needing separated +15 V and -15 V supplies for low-power functions

Design & Procurement Notes

When selecting this converter, verify that the input source remains within 36 V to 75 V and that each output current demand does not exceed 35 mA. The 1.1 W total rating and 79% efficiency affect thermal budget, especially near the 90°C upper operating temperature. The 1.6 kV voltage isolation and surface-mount 7-SMD package influence layout, spacing, and assembly considerations. The SCP feature should be considered against system fault requirements.
