The DATEL ICP232.2-5V 029.361114 is a high-isolation DC-DC converter module engineered for critical power supply applications in industrial control, medical equipment, and test instrumentation. Designed to deliver 2.2W of regulated 5V DC output from a 24V DC input, this compact converter provides reinforced isolation (1500 VDC) between input and output circuits, effectively breaking ground loops and suppressing noise in sensitive measurement systems. Its patented switching topology achieves 82% efficiency with low ripple (<50 mVpp), ensuring stable power for analog/digital circuits in electrically noisy environments. Encased in a potted metal shield, the ICP232.2-5V withstands shock/vibration (10g/5g RMS) and operates across -40°C to +85°C without derating. The suffix 029.361114 denotes a specialized variant with extended validation for aerospace and defense applications, including burn-in screening and hermetic sealing for high-altitude operation.

Main Features and Advantages
Ultra-Noise Immunity: Triple-shielded transformer design achieves 100 dB common-mode rejection at 1 MHz – critical for protecting sensitive ADC/DAC circuits in data acquisition systems.
Extended Reliability: Industrial-grade potting compound protects against humidity (100% condensing) and chemical vapors. Gold-plated pins prevent fretting corrosion in high-vibration environments.
Wide Input Flexibility: Operates down to 18V during brownouts and withstands 100V transients (50 ms) per EN 61000-4-5. Reverse polarity protection (-40V for 1 min).
Space-Optimized Design: 1″ x 1″ footprint with through-hole mounting saves PCB space. Low profile (10.2 mm) fits behind instrument panels.

Installation and Maintenance
Pre-installation preparation: Verify input polarity before energizing. Include 100 μF electrolytic capacitor within 50 mm of input pins. Maintain 3 mm creepage distance between primary/secondary traces. Use thermal vias for heat dissipation at >70°C ambient.
Maintenance recommendations: Monitor output ripple annually via oscilloscope (>100 MHz BW). Replace if efficiency drops below 75% or isolation resistance measures <100 MΩ at 500 VDC. Avoid ultrasonic cleaning to prevent potting damage.
