Performance characteristics

Output characteristics

Stable output voltage and current: capable of providing stable DC output voltage and current with high output voltage accuracy and low ripple factor. For example, under rated load, the output voltage fluctuation range can be controlled within a very small interval, ensuring reliable and stable power supply for the connected equipment, which is crucial for electronic equipment requiring high power quality, such as precision industrial control equipment and instrumentation.

Multiple output specifications available: A variety of output voltage and current combinations can be provided according to different equipment requirements. This makes it possible to adapt to a variety of devices with different voltage and current requirements, with strong versatility, for example, it can simultaneously power two devices that require 24V, 1A and 12V, 2A.

Reliability and Stability

High-quality circuit design: It adopts advanced circuit design concepts and high-quality electronic components for high reliability. Its internal protection circuit can effectively prevent abnormal conditions such as over-current, over-voltage, and short-circuit from damaging the power supply itself and the connected equipment, and it can also work stably in complex industrial environments.

Redundancy design (if any): redundancy design may be adopted in some cases. When one power module fails, another module can automatically take over the work to ensure the continuity of power supply, which greatly reduces the risk of equipment downtime due to power failure and improves the availability of the whole system.

Efficiency and Energy Saving

High conversion efficiency: In the process of power conversion, it has a high conversion efficiency, which can effectively reduce the loss of power in the conversion process. This not only saves energy and reduces operating costs, but also reduces the heat generated by low conversion efficiency, which is conducive to prolonging the service life of the power supply itself and improving the stability of the system.

Protection Function

Perfect protection mechanism: It is equipped with various protection functions, such as over-current protection, over-voltage protection, short-circuit protection and overheating protection. When there is abnormal current, voltage increase, output short circuit or internal temperature is too high, the power supply can automatically take protective measures, such as cutting off the output or adjusting the output state, to avoid damage to the equipment, and after the fault is removed, it can automatically return to normal operation.

Electromagnetic compatibility (EMC)

Good electromagnetic compatibility: electromagnetic compatibility is fully taken into account in the design, which can effectively inhibit the generation of electromagnetic interference, and at the same time, it can also resist the influence of external electromagnetic interference on itself. This makes it can work normally in industrial places with complex electromagnetic environment, and will not cause interference to other electronic equipment around, ensuring the stability and reliability of the whole electrical system.

Application Areas

Industrial automation control systems

Power supply for controllers and I/O devices: In various types of industrial automation production lines, such as automotive manufacturing, machining, food and beverage production, etc., stable power supply is provided for programmable logic controllers (PLC), remote I/O modules, sensors, actuators and other devices. The normal operation of these devices requires a high degree of power stability, and the PVZ 21 ensures that they work stably, thus guaranteeing the automated operation and precise control of the production line.

Power supply for industrial robots: Providing power support for industrial robots, industrial robots need stable power supply to ensure their high-precision movements and complex tasks, and the stable output of PVZ 21 can meet this demand.

Process control industry

Power supply for chemical and petroleum industry equipment: In the chemical and petroleum process control industry, power supply is provided for the temperature control system, pressure control system, flow control system and other equipment of the reactor. These devices play a key role in the chemical reaction and petroleum refining process, and a stable power supply helps to ensure that the production process is carried out safely and stably.

Power supply for pharmaceutical and biotechnology equipment: In the pharmaceutical production process, power supply is provided for drug synthesis equipment, fermentation equipment, filtration equipment, etc. to ensure the stability of these equipments in the production process, which is of great significance for the stability and consistency of the quality of drugs.

Intelligent Building System

Power supply for HVAC system: In the heating, ventilation and air conditioning (HVAC) system of the building, it provides power supply for the controller of the air conditioning unit, temperature sensors, humidity sensors, fan motors and other equipments to ensure the normal operation of the HVAC system and realise the intelligent regulation of the environment in the building.

Power supply for lighting and water supply and drainage systems: Provide power for the lighting systems (including intelligent lamps and lighting controllers) and water supply and drainage systems (such as water pumps, liquid level sensors, solenoid valves, etc.) in intelligent buildings, so as to realise the intelligent control and management of the lighting and water supply and drainage systems in the buildings.
