ABB NPEP03 Power Entry Panel

ABB NPEP03 Power Entry Panel

Basic Functions

As a key power conversion and distribution device, it is responsible for converting the external input AC power into various DC voltages required inside the system, such as + 5V, +15V, -15V and + 24V, etc., to provide stable power support for various types of devices in the Network 90 system, such as controllers, I/O modules, communication modules, and so on.

Filtering and voltage stabilisation of the input power supply can be achieved to ensure that the output DC power supply has a low ripple factor and high stability to meet the needs of electronic equipment with high power quality requirements.

Performance Characteristics

Input characteristics: usually can adapt to a wide range of input voltage, such as the common 100V-240V AC input voltage range, can work stably in different power supply environment, and at the same time has a high input power factor, can effectively reduce the harmonic pollution of the power grid.

Output characteristics: high output voltage stability, low ripple coefficient, can provide pure and stable power supply for electronic equipment with high requirements on power quality. With over-current protection, over-voltage protection, short-circuit protection and other protection functions, when an abnormal situation occurs, it can quickly cut off the power supply or take other protective measures to prevent damage to the equipment and ensure the safe operation of the system.

Reliability: Adopting high-quality electronic components and advanced manufacturing process, it has high reliability and stability, and can operate stably for a long time in the harsh industrial environment, reducing the system downtime caused by power supply failure.

Physical Characteristics

Size: usually 30cm long, 26cm wide and 40cm high.

Weight: approximately 3.05kg.

Application Fields

Industrial automation control system: In the automated production lines of chemical, petroleum, electric power, metallurgy, pharmaceutical and other industries, it provides stable power supply and reliable network connection for Distributed Control System (DCS), Programmable Logic Controllers (PLC), industrial computers, sensors, actuators and other equipments, to ensure efficient operation and precise control of the production lines.

Intelligent building automation system: In the automation system of an intelligent building, it provides power supply and network support for the control equipment of HVAC system, lighting system, lift system, security system, etc. in the building equipment management system (BMS), so as to realise centralised monitoring and intelligent management of building equipment.

Precautions

Installation Requirements: It should be installed in a dry, well-ventilated environment without strong electromagnetic interference, and the installation location should be convenient for operation and maintenance, and at the same time, it should be ensured that it is firmly installed to avoid damage to the equipment or loose connection due to vibration or collision.

Wiring precautions: when wiring, should be strictly in accordance with the wiring diagram of the equipment to ensure that the connection is correct, and at the same time pay attention to the tightness of the wiring, to avoid poor contact or overheating due to loose wiring and other problems.

Regular maintenance: Regular inspection and maintenance is required, such as cleaning the surface of the equipment, checking the connection lines and interfaces, checking the operation of the cooling fan, etc., so as to find and deal with potential problems in time to ensure the long-term stable operation of the equipment.

Compatibility check: It is necessary to ensure compatibility with other ABB's Net 90 series devices and systems to ensure the normal operation of the whole system and the stability of communication.
