SSR Solid State Relay Voltage Regulator 24-380V AC Output with Potentiometer

Specifications:

• Type: SSR Solid-State Relay Voltage Regulator with Potentiometer
• Output Voltage Range: 24V AC to 380V AC
• Input Voltage Range (Control Signal): 3V DC to 32V DC
• Output Type: AC (Alternating Current)
• Control Mode: Phase control or Zero-crossing trigger (depending on model)
• Application: Designed for AC voltage regulation and power control for resistive loads such as heaters, lamps, and small motors.

Electrical Specifications:

• Input Voltage: 3-32V DC (input signal to control the relay)
• Input Current: 5-20mA (depending on the applied control voltage)
• Output Voltage: 24-380V AC
• Rated Current: 10A, 25A, 40A, or 60A depending on the specific model
• Surge Current: Up to 10 times the rated current for short durations (for overload conditions)
• Output Voltage Drop: Less than 1.5V (typically 1V) when the relay is on
• Potentiometer: Manually adjustable, typically between 500Ω to 1kΩ, to regulate the output voltage.

Control and Regulation:

• Control Type: Phase angle regulation or continuous AC voltage adjustment using a potentiometer. The potentiometer allows smooth output voltage control from 0 to maximum within the specified range.
• Regulation Method: By adjusting the firing angle of the SSR, the output power is controlled, which adjusts the voltage output supplied to the load.
• Trigger Method: Zero-crossing (for resistive loads) or random phase control (for inductive loads) depending on the model.
• Response Time: Zero-crossing triggering ensures the load is switched on at the beginning of the AC cycle, reducing electrical noise and transients.
• LED Indicator: Displays the operating state of the SSR (on/off status).

Protection:

• Overcurrent Protection: Limited internal protection, typically requires external circuit breakers or fuses for safety.
• Overvoltage Protection: External devices are recommended for safeguarding against input voltage surges.
• Thermal Protection: SSRs dissipate heat during operation and may require an external heat sink or cooling fan to prevent overheating under high loads.

Mechanical Specifications:

• Mounting Type: Panel-mounted with screws or DIN rail options (depending on the model).
• Material: High-quality plastic and metal housing for durability and insulation.
• Potentiometer Control: Typically mounted on the front face of the relay, adjustable by the user to fine-tune the output voltage.
• Terminal Type: Screw terminals for secure connections of input/output wiring.

Environmental Specifications:

• Operating Temperature: -30°C to +80°C
• Storage Temperature: -40°C to +100°C
• Humidity: 10% to 90% (non-condensing)
• Cooling: Passive air cooling or heat sink is required for higher current models (20A and above).

Application Areas:

• Temperature control for ovens, heaters, and kilns
• Lighting dimming applications
• Motor speed control for small AC motors
• Power regulation in industrial equipment

Safety and Compliance:

• Certifications: CE, RoHS, UL (depending on model)
• Insulation Resistance: 1000 MΩ at 500V DC (minimum)
• Dielectric Strength: 2500V AC between input and output terminals
