The THC solid state timer from Airotronics operates in a delay on make mode, where applying input voltage initiates a time delay before energizing the load. It features a digital timing mechanism with a solid state output capable of handling a continuous load of 1 amp and a single-cycle surge of up to 10 amps. The timer supports a wide range of input voltages from 19 to 277 volts AC, with four overlapping voltage ranges available. The THC timer offers virtually unlimited timing ranges, with standard options from 0.1 seconds to 24 hours, and can be configured for either factory-fixed or variable timing adjustments. It is designed for easy installation, requiring only two connections for models with integral time adjustment. The unit is encapsulated for protection against harsh environments and includes O-ring sealed exposed controls. Additional specifications include a repeat accuracy of ±1%, a reset time of 100 milliseconds, and a dielectric strength of 1800V RMS. The timer is RoHS compliant and has been subjected to 100% operational testing prior to shipping.
THC timers are solid state output units with digital timing. The THC comes in a 2" square case. Ease of installation and hook-up is a primary design benefit. All models with integral time adjustment knob or factory-fixed time require only two connections. They may be wired in-line just like a single pole switch. Units with external time adjustment have two additional terminals for the resistor or potentiometer.
