ABB Power Supply PVZ 21 H&B Contronic

Basic information

The ABB Power Supply PVZ 21 H&B Contronic is a power supply module from ABB designed to provide stable power support for the H&B Contronic range of automation equipment and control systems.

Functional features

Stable power output: The ability to provide a stable DC output voltage, for example, an output voltage of 24V DC, and a high stability of the output voltage, whose fluctuation range is usually controlled within ±1% - ±5%, is crucial for industrial automation equipment requiring a high-precision power supply. This is critical for industrial automation equipment that requires high precision power supplies, because a stable voltage ensures that the electronic components of the equipment work properly and avoids equipment failure or performance degradation caused by voltage fluctuations.

Multiple protection functions:

Over-current protection: Built-in over-current protection mechanism, when the output current exceeds the rated current (e.g. the rated current is 5A, and the protection is triggered when the output current reaches about 6A), the power supply will automatically cut off the output to prevent the equipment from being damaged due to excessive current.

Over-voltage protection: If there is an over-voltage condition at the output, such as a voltage increase due to an external circuit failure, the power module will stop working immediately to protect the connected equipment from being damaged by the high voltage.

Short-circuit protection: In case of accidental short-circuit at the output, the power supply can respond quickly to limit the short-circuit current, avoiding safety accidents such as fire caused by short-circuit, and at the same time protects its own internal circuits from damage.

High reliability: Adopting high-quality electronic components and advanced circuit design, it has high reliability and durability. It has a long MTBF (Mean Time Between Failure), for example, more than 100,000 hours, which enables it to operate stably for a long period of time in harsh industrial environments, and reduces the downtime and maintenance costs of the equipment.

Technical Parameters

Input Voltage Range: It can usually adapt to a wide range of input voltage, such as 100 - 240V AC (alternating current), 50/60Hz, which makes it possible to work normally under the power standards of different countries and regions, and to adapt to a certain degree of fluctuations in the grid voltage.

Output power: the output power depends on the specific model, for example, it can reach about 120W, which can meet the demand of powering multiple devices at the same time, and the specific output power determines how many loads it can provide enough power for the devices.

Efficiency: The conversion efficiency of the power supply is high, generally between 70% - 90%, higher efficiency means that in the process of converting the input AC power to DC power, less energy is lost, which not only reduces energy consumption, but also reduces the heat generated by energy loss, improves the stability and service life of the power supply.

Application areas

Industrial automation control system: In the automation control system of chemical industry, iron and steel, machinery manufacturing and other industrial fields, it provides stable power supply for PLC (Programmable Logic Controller), sensors, actuators and other equipments. For example, in the automated production line, power supply is provided to the inverter that controls the motor speed, the sensor that detects the product position and other equipment to ensure the normal operation of the production line.

Intelligent Building System: Provide power support for electrical equipment in intelligent buildings such as elevator control systems, lighting control systems, security monitoring systems, etc. Taking lighting control system as an example, it provides stable power supply for intelligent dimmers, human body sensors and other devices to realize intelligent control of building lighting.

Transportation industry: It plays a role in equipment control and monitoring systems in rail transportation, port automation and other fields. For example, in the control system of subway vehicles, it provides power supply for on-board signaling equipment, door control equipment, etc., to ensure the safe operation of the train and passengers' riding experience.
