AC voltage regulator module is a high-performance single-phase (220V) or two-phase (380V) SCR power regulator, engineered for seamless phase-shifted output control. It supports flexible input options, including DC 0-5V or 4-20mA control modes, making it ideal for a wide range of industrial electric needs. With load current ratings available in 25A, 40A, 75A, 90A, and 120A, this module delivers reliable, precise power regulation to optimize performance and efficiency in your critical processes.
Q1: What are the current limits for different loads when using SCR voltage regulator module?
Resistive loads must not exceed 60% of the rated current, inductive or capacitive loads must not exceed 40%, and motor loads must not exceed 20%. This limitation prevents module overload caused by different load characteristics, ensuring long-term stable operation.
Q2: How to perform overcurrent protection for SCR voltage regulator module?
Overcurrent and short-circuit are the main causes of permanent damage to thyristors, which can directly lead to module failure. Effective overcurrent protection can be achieved by installing fast-acting fuses or air switches to avoid damage to key components.
