Model 18D-H SCR power controls utilize phase-angle firing to provide infinitely variable control of single-phase voltages to variable resistance loads such as quartz/tungsten tubes without derating These units are solid state replacements for variable transformers, saturable core reactors, electromechanical contactors and mercury relays. Power semiconductors replace contacts and brushes to switch electric power without moving parts, and when operated within their stated ratings for current voltage, and temperature, have no known MIBF or life expectancy rating.
INNOVATIVE ADVANCED TECHNOLOGY: Three Pillars Of Protection
18D-H SCR controls incorporate exclusive design features to protect power semiconductor components against damage:
1> Unique "Vbo Clamping" provides unmatched protection for power semiconductors against transient voltage spikes common on industrial power mains.
2> '2 millisecond" fuses protect semiconductors against short-circuit faults. Payne Engineering SCR controls are the only power controls in the industry equipped with factory tested and approved fuses coordinated with power semiconductors.
3> Proprietary heatsinks are engineered in-house, coordinating finite-element analysis (FEA) with on-site lab tests. Payne Engineering SCR controls operate at 500C (1220F) ambient temperatures with no derating.
Standard configuration of all Series 18D-H SCR controls is manual control via a 2700 turn potentiometer (included). A 1/2 second soft-start feature minimizes the current inrush to variable-resistance loads when first energized. Standard options allow for automatic open- or closed-loop control in response to an analog control signal from a temperature controller, PLC I/O module, or other external source. Other options allow controls to be configured for the specific requirements of each application.
Control Circuit: all solid state circuitry supplies synchronized gate firing pulses to each thyristor via isolating pulse transformers. Mains Frequency: 50 60 Hz standard. Other frequencies available as special order (consult factory).
