Details of SCR-3ATP125 Three phases 200-480VAC, current 125A, Multi-input, Phases angle

SCR-3ATP125 Three phases 200-480VAC, current 125A, Multi-input, Phases angle SCR (Silicon Controlled Rectifier) three-phase type is a voltage regulator device for three-phase electrical systems. It uses 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 power supply switch, controlled by the Gate signal to regulate circuit timing.
• Adjusting the phase angle is delaying the energy delivery time in each cycle of the sine wave, allowing control over the output voltage.
• Voltage can be continuously adjusted (0–100%) as required.
• Operates in a three-phase electrical system (3-Phase).
• Suitable for 3-phase systems of 200–480VAC, using six SCRs per circuit (two per phase).
• Designed to withstand heavy loads and industrial environments.

Features

• Continuous voltage control (0-100%)
• Multiform 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.
• Gentle motor startup control
• General industrial loads – Such as baking ovens, metal melting furnaces, factory heating systems.
• Illumination / Stage Lighting – Precise control of light levels.

Details

• Input voltage 200–480VAC (3-phase)
• Phase Angle / Zero-Cross control system
• Input types: 4-20mA, 0-10V, Potentiometer, Digital Signal
• Suitable for Resistive and Inductive loads
• Overvoltage, Overcurrent, Overheat protection
• Installation type: DIN rail or in control panels.
