2. Model Selection Guide
The model naming format is: XRE - [Design No.] [Phase/Control Type] [Rated Voltage] [Rated Current] [Switching Mode]
- Rated Output Current: 10A / 25A / 40A / 60A / 80A / 100A / 120A
- Rated Output Voltage: 22/220V, 48/480V, 38/380V, 66/660V, 120/1200V
- Phase: 1 (Single-phase), 2 (Two-phase), 3 (Three-phase)
- Control Type: D (DC control AC), A (AC control AC), DD (DC control DC)
- Switching Mode: No code = Zero-crossing type;
P = Random type
- Zero-crossing type: Constant current control (3–32VDC, trigger current ≥5mA)
- Random type: Series resistance control (4–8VDC, trigger current ≥10mA)
3. Key Functional Features
- Wide input voltage range (3–32VDC) with low control current (≤15mA)
- No moving mechanical parts: Long service life and high reliability
- Fast switching speed: Zero-voltage turn-on and zero-current turn-off, reducing RF interference
- Built-in RC absorption circuit: Protects against inrush current at startup
- Optical isolation between input and output: 2500V insulation withstand voltage
- Compact, epoxy-potted design: Vibration-proof, moisture-proof, and corrosion-resistant
Notes
- Models ≥50A are enhanced solid-state relays and require proper heat sinking.
- Random-type solid-state relays require a ballast resistor; consult technical support for details.
- Recommended mounting torque: 0.58–0.98 N·m (M4 screws) and 0.98–1.37 N·m (M3 screws). Excessive torque may damage the relay.
- Ensure tight contact with the heat sink during installation and apply thermal grease for efficient heat dissipation.
