The **KTG-11-R** is a specific model of a **Gas Ignition Transformer** (Electronic Ignitor), commonly used in industrial burners, gas furnaces, and high-efficiency heating systems. It is designed to convert low-voltage input into a high-voltage spark to ignite gas-air mixtures. --- ### 1. Key Technical Specifications The electrical characteristics of the KTG-11-R define its performance and compatibility. | Parameter | Typical Value | | :--- | :--- | | **Input Voltage** | 220V - 240V AC | | **Frequency** | 50 / 60 Hz | | **Output Voltage** | 11 kV (11,000 Volts) | | **Duty Cycle** | Intermittent (e.g., 33% at 3 mins) | | **Operating Current** | ~0.1A to 0.3A | | **Secondary Current** | ~20mA - 30mA | --- ### 2. Core Electronic Components The device functions as a solid-state electronic power supply. Unlike old-fashioned heavy copper-core transformers, the "KTG" series utilizes modern electronic switching. #### A. Input Filtering (EMI Filter) * Contains capacitors and inductors to prevent electromagnetic interference (EMI) from leaking back into the power grid. * Protects the internal circuit from voltage spikes. #### B. Rectifier and Oscillator * **Bridge Rectifier:** Converts the AC input into DC. * **High-Frequency Oscillator:** An electronic circuit (often using transistors or MOSFETs) that converts DC into a high-frequency AC pulse. This allows for a much smaller transformer core compared to standard 50Hz models. #### C. Step-Up Transformer (Ferrite Core) * The high-frequency pulse is fed into a specialized ferrite-core transformer. * The high turn ratio increases the voltage from ~300V (internal) to the required **11,000V** at the output terminal. #### D. Potting Compound (Insulation) * The internal electronics are encased in an **epoxy resin** or "potting" material. * **Purpose:** Provides high dielectric strength to prevent internal arcing and protects components from moisture, vibration, and dust. --- ### 3. Connection and Safety The KTG-11-R typically features three primary connection points: 1. **L / N (Line/Neutral):** The power input terminals (usually 220V). 2. **Earth / Ground:** Vital for the return path of the high-voltage spark. 3. **High Voltage Out:** The single-pole terminal where the ignition cable is attached. --- ### 4. Installation Checklist ```markdown 1. Ensure the power is OFF before handling the HV cable. 2. Maintain a spark gap distance of 3mm to 5mm between the electrode and the burner head. 3. Check the grounding wire; a poor ground will lead to weak sparks or device failure. 4. Avoid continuous operation (ensure the control box cuts power once flame is detected). ```
