ABB NSPS01 Power Supply

Basic Information

Input Characteristics

Input Voltage Range: It is usually able to adapt to a wide input voltage range, which makes it work stably in different grid environments. For example, its input voltage range may be 100 - 240V AC (alternating current), 50/60Hz. This wide range of input voltage adaptability allows it to work properly in most of the global grid environments and reduces the risk of equipment malfunctions due to fluctuations in grid voltage.

Input Current: Under the rated input voltage, the amount of input current is related to the power of the power supply. Generally speaking, it will be reasonably designed according to the output power requirement to ensure that it will not cause excessive burden on the power grid during normal operation.

Output Characteristics

Output Voltage: Provide stable direct current (DC) output voltage, the common output voltage has 24V DC. this voltage is the common working voltage for many devices in industrial automation system (such as PLC, I/O modules, sensors, etc.), and it can provide reliable power supply support for these devices.

Output Current and Power: The amount of output current determines how many devices or how powerful it can power. For example, it may have a large output current capacity, such as 5A or 10A and other different specifications, and the corresponding output power can be calculated according to the formula P = UI (P is power, U is voltage, and I is current), which makes it possible to provide sufficient power for multiple load devices at the same time.

Functional features

High stability

Adopting advanced voltage stabilisation technology, it can keep the output voltage stable in the case of input voltage fluctuation and load change. For example, when the number of connected devices suddenly increases or decreases (i.e. load changes), it can automatically adjust the output to ensure that the output voltage is always stable near the set value, with an error range usually between ±1% - ±5%, which is very important for industrial equipment with high requirements for voltage stability.

Perfect protection function

Overcurrent protection: When the output current exceeds the rated current, the power supply will automatically activate the overcurrent protection mechanism to limit the output current or cut off the output, in order to prevent the power supply and the connected equipment from being damaged by excessive current. For example, if a short-circuit fault occurs in a device, resulting in an instantaneous increase in current, the power supply will quickly detect it and take protective measures.

Over-voltage protection: Similarly, in the event of an abnormally high output voltage, the over-voltage protection function is triggered to protect the connected devices from damage caused by excessive voltage. This protection mechanism is usually realised by internal voltage monitoring and control circuits.

Short-circuit protection: If a short-circuit situation occurs at the output, the power supply will not be damaged as a result, but will automatically cut off the output current. After the short-circuit situation is lifted, some power supplies can also automatically resume normal operation, which greatly improves the reliability of the power supply in complex industrial environments.

High reliability

Adopting high-quality electronic components and reliable circuit design, it can operate stably for a long time in harsh industrial environments. For example, it can work normally in the temperature range of - 20 ℃ - + 70 ℃, and in the case of high relative humidity (such as 5% - 95%) can still maintain stable performance, but also has a certain degree of anti-electromagnetic interference ability, can resist the electromagnetic interference generated by other equipment in the industrial field.

Application Scenarios

Industrial automation control system

In factory automation production lines, stable power supply is provided for PLCs (programmable logic controllers), I/O terminal units, sensors, actuators, and other equipment. For example, in an automotive production line, 24V DC power is supplied to equipment such as PLCs controlling robot movements, sensors detecting the position of parts, and actuators driving motors, ensuring efficient and stable operation of the production line.

Process Control System

In the process control system of chemical, petroleum, electric power and other industries, it is used as the power supply for various control equipment and instruments. For example, in the chemical production process, it provides power support for temperature controllers, pressure transmitters, flow regulating valves and other equipment to ensure the accuracy and reliability of process control.

Intelligent Building Automation System

Play a role in the HVAC (heating, ventilation and air conditioning) system, lighting system, lift system, etc. of intelligent buildings. For example, they provide power for temperature sensors, air conditioning unit controllers in the HVAC system, intelligent lamp controllers in the lighting system, and control panels in the lift control system, enabling automated control of equipment and energy management in the building.
