Details of SCR-3ATP045 Three phases 200-480VAC, Current 45A, Multi-input, Phase angle

SCR-3ATP045 Three phases 200-480VAC, Current 45A, Multi-input, Phase angle SCR (Silicon Controlled Rectifier) three-phase type is a voltage regulator device for three-phase electrical systems using SCR as the main component to control AC input voltage of 200–480VAC by adjusting the “phase angle” (Phase angle control).

Principle of Operation

• The Phase Angle Control SCR acts as a switch controlling power delivery, using Gate signal to control circuit timing.
• Adjusting phase angle is delaying the time of energy delivery in each cycle of sine wave, allowing control over output voltage.
• Voltage can be adjusted continuously (0–100%) as required.
• Operates in a three-phase electrical system (3-Phase).
• Suitable for 3-phase systems 200–480VAC using six SCRs per circuit (two per phase).
• Designed to withstand heavy loads and industrial environments.

Features

• Continuous voltage control (0-100%)
• Multifunction input control support (Multi-input such as 4-20mA, 0-10V, Potentiometer, Digital)
• Selectable control modes like Phase Angle, Zero-Cross (in some models)
• Various protection systems including Overload, Overheat, Short Circuit
• Suitable for continuous operation.
• Easy to install in control panels with monitoring functions.

Applications

• The SCR Three Phase is often used in applications requiring three-phase power or temperature control such as: Electric furnaces / Induction furnaces.
• Temperature control through voltage regulation.
• Heater Load – Used to control heaters in industrial systems, such as drying ovens and heating systems.
• Smooth motor startup control.
• General industrial loads – Such as baking ovens, metal melting furnaces, factory heating systems.
• Illumination / Stage Lighting – Precise light level control.

Details

• Voltage input 200–480VAC (3-phase)
