ULVAC CRYOGENICS INCORPORATED 1
1. Features and Types
1.1. Features
Super Trap Temperature Controller STC-1C series can display the temperature of 80K
panel by means of connecting K thermocouple mounted on our CRYO-T Super Trap
series, and can adjust the temperature of 80K panel within the range of setting
temperature by means of turning the trap refrigerator power ON and OFF. The
appearance of STC-1C series is shown on Figure 1-1 below.
This series has two types: STC-1C and STC-1C (INV). The main difference between
them is how to control refrigerator power. STC-1C is a relay control method: it is
connected between the compressor unit and the refrigerator, and turn refrigerator
power line ON and OFF by relay. On the other hand, STC-1C (INV) is an inverter
control method: it controls On command of refrigerator with the inverter mounted on
the compressor as an optional. Figure 1-2 below shows types of STC-1C series.
