10 Dimensions:51.0x10.5x40.6mm (2.0x1.6x0.42in)

11 Additional Functions:Shutdown input for remote control, flex power (flexible load distribution), magnetic feedback for stable regulation, no output voltage overshoot when using inhibit function (option i)

使用场景 APPLICATIONS

1 Transport & Railway: Suitable for railway signaling systems, vehicle-mounted electronics (trains, buses) that need stable power conversion under variable input or high transient voltages

2 Industrial Automation: Applied in industrial control systems, PLCs, industrial sensors, automation devices to convert unstable DC inputs to consistent 3.3V output

3 Telecom & Communication: Used in telecom base stations, communication racks, data transmission devices requiring high isolation and reliable power conversion

4 Stationary Power Systems: Ideal for stationary industrial power supplies, backup power units, distributed systems operating in harsh environments (-40°C to85°C)

5 Specialized Scenarios: Devices needing compliance with EN50155 (railway) and EN50121-3-2 (railway EMC) standards, or protection against input transients/overloads

注意事项 PRECAUTIONS

1 Installation: Must connect to a secondary circuit; follow national safety regulations for enclosure, mounting, creepage, clearance

2 Physical Handling: Do not open the converter; avoid cleaning fluid penetration (not hermetically sealed); open-frame models (option Z) only clean with room-temperature isopropyl alcohol

3 Thermal Management: Ensure case temperature (TC) does not exceed specified limits; TA max is indicative—installer must verify TC compliance

4 Protection: Use external fuse F1.0A (for110IMY15 models) in non-earthed input line; overtemp protection uses hiccup mode (auto-restart after cooling)

5 Input/Output: If inhibit function (option i) is unused, connect to Vi-; follow correct wiring for R/Trim inputs to adjust output voltage

6 Connection: Parallel/series output connection needs proper precautions; double-output models track each other, so overvoltage protection is on one output

7 Guarantee: RoHS lead-free-solder products (temp index-8) have5-year warranty; non-RoHS models have different terms
