CARLO GAVAZZI 480VAC 1-PH 3-PH POWER FACTOR RELAY (DWB01CM4810A)
Enhance your electrical system monitoring with the CARLO GAVAZZI DWB01CM4810A, a high-precision TRMS power factor relay designed for three-phase balanced applications. Manufactured in Italy, this relay is RoHS compliant and features a robust box package suitable for DIN-rail mounting or plug-in modules.
TRMS load guard relays for three-phase balanced systems
Monitors power factor (cos ϕ) within set limits
Measures its own power supply
Current measurement options: 5A, 10A, MI current transformers
Adjustable power ON delay: 1 to 30 seconds
Separately adjustable upper and lower power factor levels
Programmable latching or inhibit functions at set levels
Automatic and manual start/stop operation
Output: 8 A SPDT relay, N.O. or N.C. selectable
Mounting options: DIN-rail (DWB01) or plug-in module (PWB01)
Housing: 45 mm Euronorm (DWB01) or 36 mm plug-in (PWB01)
LED indicators for relay status, alarm, and power supply
Application & Operation
The DWB01 and PWB01 relays are ideal for monitoring the load of asynchronous motors and other symmetrical loads. They measure the power factor (cos ϕ), which is proportional to the load, enabling indirect detection of underload and overload conditions. The relays support various modes including latching, non-latching, start/stop, and inhibit functions, with configurable upper and lower setpoints for precise control.

The relay measures the cosine of the angle between motor current and voltage, providing an accurate assessment of load conditions. It supports manual start/stop and automatic operation modes, with configurable delay settings to prevent false alarms during motor startup. Suitable for monitoring systems requiring precise power factor control and load management.
For more detailed specifications and wiring diagrams, please refer to the datasheet.
Note: The datasheet was not processed; please search the internet for the part number for more details.
Unfortunately I havent tested the 5G, Only difficult part was connecting antennas. But everything is good, by default it runs on Qualcom's QMI mode, Had to switch to MBIM and it works good with Windows. Planning to run with OpenWRT soon.
