GE | IS220PSFDH1A | Flame detector power module
The GE IS220PSFDH1A is a flame detector power supply module, which is an important component of the gas turbine control system. The following is an introduction to its product description, parameters, specifications, series, features, functions, uses, and application fields:
- Product Description6: The IS220PSFDH1A is a flame detector power supply manufactured by General Electric, belonging to the Mark VI series. It is used to supply power to the flame detector circuit on the primary gas turbine trip protection (TRPG) board, converting 28V DC to 335V DC.
- Product Parameters6
- Maximum Input Voltage: 29.4V DC.
- Under Voltage Lock – out Range: 22.1 – 26.4V DC.
- Inrush Current Limit: 550mA for 40μs, 300mA steady – state.
- Output Rated Value: 335V DC, 5mA.
- Output Over – voltage Protection: 385V MOV.
- Voltage Isolation, Output to Input: 1700V DC.
- Product Specifications2
- Cooling Method: Convection cooling, without cooling fans.
- Working Temperature Range: -30℃ to +65℃.
- Enclosure Type: Housed in a rectangular enclosure, with the component ID number, three diagnostic LEDs (one red and two green), and an unused IR port on the front faceplate.
- Mounting Method: Usually mounted above the TRPG board on a sheet metal surface using mounting studs, brackets, and a mounting plate.
- Series2: It belongs to the Mark VI series of General Electric, which is a functional upgrade of the Mark V series. The Mark VI series expands the application range to wind turbines and other alternative energy fields.
- Features6
- Convection Cooling Design: Without the need for cooling fans, it reduces the failure rate caused by fan failures and is suitable for harsh industrial environments.
- Input Filtering: Minimizes the sensitivity to input interference and limits emissions, ensuring stable operation of the power supply.
- Current Limiting Protection: Both the input and output have current – limiting functions. The output limiter limits the current to 7mA, and the inrush current for soft – start hot – swap input is capped at 550mA, which can protect the circuit and connected equipment.
- Output Over – voltage Protection: Equipped with a 385V MOV to provide transient protection for the output, preventing the output voltage from being too high and damaging the load.
- Function2: Its main function is to provide a stable 335V DC power supply for the flame detector circuit on the TRPG board, ensuring the normal operation of the flame detector, so as to detect the flame status in the gas turbine in time and provide key signal support for the safe and stable operation of the turbine.
- Use2: It is used in conjunction with the TRPG board. Through the J3 – J5 connectors of the TRPG board, it supplies power to the flame detector, and can monitor the output voltage through a differential pair of TP test points.
- Application Fields4: Mainly used in gas turbine control systems, which are widely used in the power generation industry, such as gas – fired power plants. It is an important part of the turbine control system, responsible for providing power support for the flame detection link to ensure the safe and efficient operation of the turbine.
