The **AM2D-4805SH30-RZ** is a high-performance DC-DC converter manufactured by **Aimtec**. It is designed to provide isolation and voltage regulation in industrial and telecommunication environments. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Input Voltage Range** | 36V to 72V DC (48V Nominal) | | **Output Voltage** | 5V DC | | **Output Current** | 400 mA (Max) | | **Power Rating** | 2 Watts | | **Isolation Voltage** | 3000 VDC | | **Package Type** | DIP14 (Dual In-line Package) | | **Efficiency** | ~75% to 80% | --- ### 2. Functional Characteristics * **Isolation (3000 VDC):** The "H30" in the part number signifies high isolation (3kV). This protects sensitive logic-level components from high-voltage surges on the input side. * **Regulated Output:** Unlike simple unregulated converters, this "S" (Single) series maintains a stable 5V output even if the input voltage fluctuates within the 36-72V range. * **Protection Features:** * Continuous Short Circuit Protection. * Operating temperature range typically spans from **-40°C to +85°C**. * **Compact Footprint:** The DIP14 form factor allows it to be integrated into space-constrained PCB designs. --- ### 3. Pinout Configuration (Standard DIP14) While you should always consult the specific datasheet for the latest revision, the standard internal configuration for this series is as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | -Vin | Negative Input Voltage | | 7 | NC | No Connection | | 8 | NC | No Connection | | 9 | +Vout | Positive Output Voltage | | 11 | -Vout | Negative Output Voltage | | 14 | +Vin | Positive Input Voltage | --- ### 4. Common Applications 1. **Industrial Controls:** Powering 5V microcontrollers and sensors from a 48V industrial bus. 2. **Telecommunications:** Converting standard 48V telecom rack power to logic-level voltages. 3. **Data Acquisition:** Providing isolated power to analog-to-digital converters to eliminate ground loops and noise.
