ABB 3HNA010325-001 is a thyristor DC speed control intermediate pressure plate card component produced by ABB.
Electrical Parameters
Electrical Parameters
-
- Input Voltage: It may be suitable for common industrial DC voltages, such as 220V, 380V, etc., to meet different power supply requirements.
- Output Current: According to its role in the DC speed control system, it may have a certain current output capacity, such as ranging from several amperes to dozens of amperes, to drive the thyristor.
- Frequency Range: The signal frequency range it can handle may be relatively wide to adapt to signal processing under different speed regulation requirements, for example, ranging from dozens of hertz to several hundred hertz.
-
Interface Parameters
- Input Interface: There may be various types. For example, the analog input interface is used to receive analog control signals from the controller, which may be standard signals of 0 – 10V or 4 – 20mA; the digital input interface is used to receive digital control commands or status signals.
- Output Interface: It is mainly used to connect to the thyristor. It may be a pulse output interface with high driving capability, which can output pulse signals with a certain amplitude and width to trigger the conduction of the thyristor.

Protection Parameters
- Overcurrent Protection: It has an overcurrent protection function. When the output current exceeds the set value, it automatically cuts off the output or takes current limiting measures to protect the card component and other devices from damage caused by overcurrent. The possible overcurrent protection value is about 1.5 – 2 times the rated current.
- Overvoltage Protection: It can withstand a certain overvoltage situation. When the input voltage or output voltage exceeds the specified value, it takes protective actions to prevent the card component from being damaged due to overvoltage. The overvoltage protection value may be 1.2 – 1.5 times the rated voltage.
- Overheating Protection: A temperature sensor is installed. When the internal temperature of the card component is too high, the overheating protection mechanism is activated, such as stopping working or reducing the load, to avoid performance degradation or component damage caused by overheating. Usually, the overheating protection temperature is around 80 – 100°C.
