Temperature Controllers www.tempco.com | (800) 323-6859 | email: [email protected] 13-84 SCR Power Controller “B” Series—Single Phase 60 through 1200 Amp The “B” Series SCR Power Controllers are a compact and economical power control solution for industrial applications that require high reliability and long life. The fast solid state switching provides superior per- formance over relays, contactors and other slower cycling controllers by reducing tem- perature variations associated with the longer on-off cycles of those devices. The result is a more precise control of the heating process and extended heater life. Command Signals: 4-20mA; 0-5 VDC; 0-10 VDC; potentiometer Control Mode: Distributive Zero Cross; Phase Angle Firing Load current: Zero Cross or Phase Angle Fire Output Amperage Ratings: 60, 90, 120, 180, 225, 350, 500, 650, 800, 1000, 1200 Line Voltage: 120, 240, 480, or 575 VAC; 10% to 20% 50/60 Hz Zero and Span: Factory pre-set. User adjustable over a range of 20% of span. Transient Voltage and dv/dt: 200 volts/microsecond minimum. Uses a dv/dt snubber and a metal oxide varistor (MOV). Control Range Zero Cross: 0 to 99.5% of line voltage Phase Angle Firing: 0 to 97% of line voltage Linearity Zero Cross: Linear with respect to the command signal Phase Angle Firing: RMS load voltage is linear within 2% of the command signal.
