Littelfuse/SSAC switching relays & controls are simple controls performing a specific function such as changing lamp intensity; vary the speed of a motor; or manage temperature of a heater.
The Littelfuse SSAC PHS Series is an ideal method of changing lamp intensity, varying the speed of a fan/motor, or controlling the temperature of a heater. The effective output voltage is adjusted with an accessory external potentiometer suitable for line voltage applications.
Littelfuse SSAC SIR series is designed for industrial applications requiring rugged reliable operation. Provides an optically isolated, high capacity, solidstate output, with power switching capability up to 20A steady state, 200A inrush. Zero voltage switching SIR2 extends the life of an incandescent lamp up to 10 times. Random switching SIR1 is ideal for inductive loads. When fully insulated female terminals are used on the connection wires, the system meets the requirements for touch-proof connections.
The Littelfuse SSAC SLR Series has no isolation between the control switch input and the solid-state output. Select the SLR for applications where the control switch is the same voltage source as the load. Provides the noiseless, reliability and long life of a solidstate relay, without the cost of isolation circuitry. Zero voltage switching SLR2 can extend the life of an incandescent lamp up to 10 times its normal life. Random switching SLR1 is normally used for inductive loads. When fully insulated female terminals are used on the connection wires, the system meets the requirements for touch-proof connections.
The Littelfuse SSAC TCR9C of solid-state temperature control is a low cost modular approach to accurate control of temperature. The high power output is available in 6, 10 and 20 amperes and provides setpoint temperature control. The efficient mounting surface allows for utilization of equipment as the heat sink. Designed for use with resistive loads.
