Power monitoring relay
- This is a relay that monitors the phase sequence, overvoltage, undervoltage, and phase loss (below 60% of the rated operating voltage) of a three-phase power supply. - The monitoring voltage range is adjustable. - It monitors the three-phase voltage within the range. - It is possible to select either on-delay or off-delay (0.1-10 seconds).
Maximum DC 1500V / AC 1100V, supports system leakage capacitance up to 3000μF! Insulation monitoring for ungrounded circuits.
The ABB insulation monitoring relay for non-earthed circuits (CM-IWx series) monitors insulation degradation and immediately issues a warning when it falls below a set minimum threshold. This enhances system reliability and reduces downtime. It supports up to DC 1500V and AC 1100V. Additionally, its unique measurement technology takes into account system leakage capacitance of up to 3000μF. By using ABB's insulation monitoring relay, insulation monitoring becomes safer and maintenance smarter. 【Features】 ■ Prevents fires by detecting aging degradation of insulation resistance ■ Easy adjustment of set values using the rotary switch located on the front of the device ■ Device status is displayed with easy-to-read and understand LEDs ■ Variants approved for railways and ships are available *For more details, please refer to the PDF materials or feel free to contact us.
Carlo Gavazzi Monitoring Relay: Reliable Monitoring Solutions | Japan's Only Distributor: Yashima Industry
Carlo Gavazzi offers automation monitoring relays based on an easy-to-use DPD concept. This allows users to set up the units directly, accommodating a variety of needs. It can monitor various electrical parameters such as voltage, current, frequency, power factor, and phase sequence. There are three installation options available, supporting a wide range of installation environments including industrial control panels, plug-in sockets, and low-profile DIN rails. It supports diverse applications such as three-phase power, current, voltage, and temperature monitoring. In particular, the three-phase power relay can monitor phase abnormalities and voltage anomalies with a single device. Current monitoring is compatible with both AC and DC, and can handle high currents with external current transformers. Voltage monitoring supports single-phase/three-phase and AC/DC, making it suitable for battery monitoring as well. Temperature monitoring is compatible with NTC/PT100 sensors and can be utilized in industrial and building automation fields. It also features power and power factor monitoring capabilities, allowing for the detection of load fluctuations and power factor anomalies. Frequency monitoring enables high-precision measurements of three-phase systems thanks to the DPD concept. The latest DTA71/72 temperature relays are compatible with a variety of sensors and are suitable for a wide range of applications.
