The **HPE-15-R** is a high-performance, high-voltage regulated DC-to-DC converter module, typically manufactured by companies like *Ultravolt* (Advanced Energy). It is designed for precision applications requiring a stable high-voltage output in a compact, PCB-mountable package. --- ### 1. Key Electronic Specifications Below are the primary electronic characteristics of the HPE-15-R module: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | +24 VDC (Typical range: 23V to 30V) | | **Output Voltage** | 0 to 15,000 VDC (15 kV) | | **Output Power** | 15 Watts (Maximum) | | **Polarity** | Reversible (Indicated by the "R" suffix) | | **Ripple/Noise** | < 0.01% peak-to-peak | | **Efficiency** | > 75% at full load | | **Temperature Coefficient** | 25 ppm/°C | --- ### 2. Core Internal Components The module consists of several critical electronic stages to achieve stable high-voltage conversion: * **PWM Controller:** Regulates the switching frequency to maintain output stability despite input fluctuations. * **Power Oscillator:** Converts the low-voltage DC input into a high-frequency AC signal. * **Step-up Transformer:** A specialized high-turns-ratio transformer with high insulation integrity to boost the voltage. * **Voltage Multiplier (Cockcroft-Walton Cascade):** A network of high-voltage capacitors and diodes that rectifies and multiplies the AC from the transformer into the final 15kV DC output. * **Feedback Network:** A high-precision resistive divider that sends a scaled-down voltage signal back to the control circuit for closed-loop regulation. --- ### 3. Control and Monitoring Interface The "R" series typically features an analog interface for integration into larger systems: 1. **Remote Programming:** Allows the user to set the output voltage (0-15kV) using a 0 to +5V or 0 to +10V control signal. 2. **Voltage Monitor:** Provides a low-voltage analog output (usually 0-5V) that represents the actual high-voltage output for telemetry. 3. **Current Monitor:** Provides a signal proportional to the output current. 4. **Enable/Disable Pin:** A digital logic pin to turn the high-voltage output on or off safely. --- ### 4. Safety and Protection Features * **Arc Protection:** Internal circuitry prevents damage from high-voltage arcing. * **Short Circuit Protection:** Limits current to prevent component failure if the load is shorted. * **Thermal Management:** The unit is typically encapsulated in a thermally conductive epoxy to dissipate heat and provide electrical insulation. ---
