Thyristortreiber -st

Aplication :
group control of anti-parallel coupled thyristors in three-phase circuits, such as :
• resistance furnaces
• airconditioners with electrical heating
• paint driers

Features:
• high user qualities
• over-voltage proof
• mounting comfort

Operational advantages:
• input control signals: 0-10V, 4-20mA
• manual control with potentiometer
• interlock input (BL-GND clamps)
• correct phase order indication
• built-in short-circuit protection
• convenient on-rail mounting (35mm)
• easy cable connection
