Struggling with relay scheme performance testing?

The WDS-2 Dual Circuit Breaker Simulator is here to help! Here’s how to use it effectively:

1️⃣ Power On: Connect the device to a 220V or 110V power supply. The simulator starts in a tripped state with phase indicators lit.

2️⃣ Action Phase Selection: Simulate three-phase, single-phase, or any combination of phases using the phase selection switch.

3️⃣ Coil Resistance Adjustment: Choose from 100Ω, 200Ω, or 400Ω resistance settings to match real-world breaker conditions.

4️⃣ Timing Settings:

• Closing Time: Adjust from 20ms to 180ms in 20ms steps.
• Tripping Time: Set between 30ms to 90ms in 10ms increments for precise control.

5️⃣ Manual Operation: Use the manual tripping and closing buttons to simulate signals and test responsiveness.

6️⃣ Auxiliary DC Output: Utilize the 110V/220V DC output with a 200W capacity to power other devices during testing.

The WDS-2 is the ultimate tool for simulating three-phase and single-phase circuit breakers, ensuring your relay schemes perform flawlessly.
