ABB Electrical 1SVR430750R0400 Voltage Monitoring Relay

Basic Introduction

The ABB Electrical 1SVR430750R0400 Voltage Monitoring Relay is a voltage monitoring relay manufactured by ABB for monitoring single-phase AC or DC voltages to ensure that the voltage in an electrical system is within a set range, thus protecting electrical equipment from voltage anomalies.

Functional features

Wide voltage monitoring range: the measurement range of this relay is wide, covering 3-30V, 6-60V, 30-300V, 60-600V, etc. It can adapt to the electrical systems of different voltage levels, and can be widely used in voltage monitoring of various industrial and civil electrical equipment.

AC/DC universal: its rated control voltage supply is 24-240V AC/DC, which means that it can be used for AC voltage monitoring as well as DC voltage monitoring, greatly improving its versatility and scope of application and reducing the need for different types of relays.

Multiple output configurations: 2x1 C/O or 1x2 C/O contact outputs, and configurable, according to the specific control needs of the flexibility to choose the output mode, easy to connect and control with other electrical equipment, such as connecting to the alarm device, control switches and so on.

Time delay function: It has a time delay setting function with a time range from 0 to 0.1s-30s, which can be adjusted according to the actual application scenario and equipment requirements. This function can avoid false action caused by instant voltage fluctuation and improve the accuracy and reliability of monitoring.

Technical Parameters

Input parameters: rated voltage is 24-240V AC/DC, measuring range includes 3-30V, 6-60V, 30-300V, 60-600V, etc., which can be adapted to a variety of different voltage levels of the input signal.

Output Parameters: The output is 2x1 C/O or 1x2 C/O contact, and the contact capacity is AC12 230V 4A, DC12 24V 4A, AC15 230V 3A, DC13 24V 2A, which is able to satisfy the control demand within a certain power range.

Accuracy: Although the specific accuracy value is not explicitly given, as a professional voltage monitoring relay, its voltage measurement and monitoring accuracy can meet the requirements of industrial-grade applications, ensuring accurate detection of voltage abnormalities.

Response time: Related to the time delay setting, its response time to voltage abnormality is outside the configurable time delay range, which can quickly detect the voltage out of the set range and output the corresponding signal in time to protect the safety of the equipment.

Application Fields

Industrial automation: In the process of industrial production, it can be used to monitor the power supply voltage of all kinds of electrical equipment, such as motors, transformers, frequency converters, etc., to ensure that the equipment operates within the normal voltage range, to prevent damage to the equipment due to over-voltage or under-voltage, and to ensure the continuity and stability of production.

Power system: It can be applied in power facilities such as substations, distribution rooms, etc. to monitor the grid voltage in real time, and send out alarm signals or take corresponding control measures in time when the voltage is abnormal, so as to guarantee the safe and stable operation of the power system.

Renewable energy system: in solar power, wind power and other renewable energy systems, used to monitor the input and output voltages of inverters, energy storage equipment, etc., to ensure the normal operation of the system and the efficiency of energy conversion.

Commercial and Civil Buildings: In the electrical systems of commercial buildings and civil residences, it can monitor the voltage of lighting systems, air-conditioning systems, lifts and other equipment to ensure the normal operation of such equipment, improve the reliability and service life of power-using equipment, and at the same time help to save energy.
