Enhance your electrical system's reliability with the CARLO GAVAZZI Industrial Load Guard Relays, designed for monitoring 3-phase loads and motor performance. These relays are ideal for applications requiring precise cos φ monitoring, overload, and underload detection, ensuring optimal operation and protection of your electrical equipment.
Product Features
Type: Monitoring relays with 3-phase load guard functionality
Voltage Range: 240VAC (Power Supply: 208-240 VAC)
Current Measurement: 5A standard, compatible with MI current transformers
Output: 8 A SPDT relay, Normally Energized
Housing Options: 22.5 mm Euronorm DIN-rail mounting (DWA01) or 36 mm plug-in module (PWA01)
Adjustable Power ON delay: 1, 2, or 6 seconds
Knob adjustable level on an absolute scale from 0.1 to 0.99 for cos φ monitoring
LED Indicators: Power supply status and output ON
Mounting: DIN-rail or plug-in module in accordance with DIN/EN 50 022
Monitoring Capabilities: Measures voltage, current, and power factor (cos ϕ) for balanced systems
Application: Suitable for asynchronous motor load monitoring, overload, and underload detection
The DWA01 and PWA01 relays are designed for monitoring the actual load of asynchronous motors by measuring the 3-phase supply voltage and the current of phase L1. They monitor the cosine of the phase angle (cos ϕ), which varies with motor load, allowing indirect detection of overload or underload conditions.
Overload monitoring: The relay operates and the yellow LED indicates status when cos ϕ drops below the set limit. It releases when the limit is exceeded.
Underload monitoring: The relay operates and the yellow LED indicates status when cos ϕ exceeds the set limit. It releases when the load drops below the set threshold.
The relays feature an inhibit delay at power-on to prevent false alarms during motor startup, ensuring reliable operation.

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.
