Traco Power THN 30-2423WI

Summary of Traco Power THN 30-2423WI Product

The Traco Power THN 30-2423WI is a high-performance isolated DC/DC converter module, engineered to deliver robust and reliable ±15V outputs with up to 1A per channel from a wide input voltage range of 9V to 36V. Designed as part of the renowned THN 30WI series, this converter provides a compact solution with a remarkable power density of 30W, making it an ideal choice for space-constrained designs in industrial, communications, and instrumentation sectors. Open-frame in a shielded metal case, the device guarantees galvanic isolation rated to 1.6kV, supporting demanding ITE (Information Technology Equipment)/commercial environments.

Main Attributes and Performance Details of Traco Power THN 30-2423WI

The THN 30-2423WI distinguishes itself with a suite of technical features aimed at maximizing efficiency, safety, and design flexibility. Its ultra-wide 4:1 input range allows for reliable operation in fluctuating supply scenarios, while a best-in-class conversion efficiency of up to 91% ensures minimal losses and cooler operation. Integrated protections—over-temperature, over-voltage, short-circuit, and under-voltage lockout—safeguard both the converter and connected loads. The remote On/Off control and output voltage adjustability offer greater system integration freedom, particularly valuable in battery-powered or energy-sensitive systems. Regulation is precise, with output voltage set accuracy held within ±1%, exhibiting strong line and load regulation for mission-critical performance.

Electrical Input and Output Parameters for Traco Power THN 30-2423WI

From a power supply design perspective, the THN 30-2423WI’s input and output parameters provide predictable system behavior and simplified design-in. With a nominal input voltage range from 9V to 36V and minimal no-load input current (10mA typ. at 24V in), efficiency remains high even during system standby. Surge tolerance and input protection accommodate brief over-voltage events, while the internal Pi-type filter ensures compliance with EMC requirements.

On the output side, the converter supports dual outputs: +15V and -15V at up to 1A each, with ripple and noise rated at 60mVp-p typically (using recommended external capacitors for optimal filtering). Output voltage can be fine-tuned via external trimming (±10%), and robust overload/short-circuit protection maintains the reliability of downstream circuits. The device supports dynamic response requirements with a fast transient response (250μs typ. for a 25% load step), suitable for sensitive analog and mixed-signal loads.

Heat Dissipation and Environmental Standards of Traco Power THN 30-2423WI

Designed with reliability in mind, the THN 30-2423WI supports operating temperatures from -40°C up to +80°C (derated), and up to +85°C when used with an optional heat sink. The thermal impedance from case to ambient is 15K/W typ., improving to 13.8K/W with heat sinking. Protection against overheating is implemented, with automatic shutoff and recovery to ensure safe long-term operation. Environmental compliance covers full RoHS (ROHS3) and REACH standards, with non-conductive, flame-retardant potting (FR4, UL94 V-0), making the module suitable for modern, eco-conscious designs. The converter is further qualified per MIL-STD-810 for vibration and thermal shock, extending application possibilities into rugged industrial domains.

Structural Design and Installation Alternatives of Traco Power THN 30-2423WI

The form factor of the THN 30-2423WI is highly optimized: a mere 1.00" x 1.00" x 0.39" (25.4mm x 25.4mm x 9.9mm), weighing just 16.5g. This enables designers to deploy high-density power conversion in tight PCB layouts. The device utilizes a standard 6-DIP through-hole footprint for secure PCB mounting and ease of automated wave soldering. Its robust, shielded metal housing and isolated baseplate mitigate EMI concerns, supporting both conducted and radiated emissions compliance with EN 55032 (Class A/B with external filtering). The pinout is thoughtfully arranged for single or dual output applications, with clear provisions for remote control and output voltage trimming.

Use Cases for Traco Power THN 30-2423WI

The versatility of the THN 30-2423WI lends itself to a range of demanding applications. Mobile equipment requiring high reliability and extended battery life benefit from the unit’s low standby input current and remote control features. Instrumentation circuits needing tightly regulated bipolar supplies find the dual ±15V outputs ideal for signal conditioning and analog front ends. Distributed power architectures in communication and industrial settings take advantage of the unit’s high efficiency and isolation ratings, supporting modular and scalable power solutions. The module’s compact footprint allows engineers to maximize valuable PCB real estate, particularly in densely populated or miniaturized systems.
