RELIABILITY
NO MOVING PARTS = MTBF 10x
BETTER THAN CONTACTORS
AND 2x MORE THAN SOLID
STATE RELAYS. THIS MEANS
LOWER MAINTENANCE COSTS,
INCREASED PROCESS TIME AND
EXTENDED SWITCH LIFETIME.

SCRs CAN BE SWITCHED ON AND
OFF AT A CONFIGURABLE SINE
WAVE POINT TO OPTIMIZE POWER

SCRs CONTROL POWER BY ADJUSTING THE OUTPUT POWER REQUIRED BY THE PROCESS TO MATCH REAL-TIME
TEMPERATURE INPUT, ENABLING BETTER TEMPERATURE REGULATION, WHICH CAN EXTEND HEATER LIFE AND
IMPROVE PRODUCT YIELDS.
