1. Output of the outside sealed transformer:AC12V(one transformer matched with one temp. controller)
2. Temperature sensor: NTC, Double sensors(for cold-room temp.&defrost control),2m(L)
3. Range of temperature displayed :-45~ 66 ℃ (-45 ~ 150 ℉) Accuracy ± 1 ℃ (± 2 ℉)
4.Range of set temperature: -45 ~ 45 ℃ (-45 ~ 120 ℉)
5.Compressor: N.O. 20A/250VAC (applicable to 1 HP Compressor,if more it needs to connect an AC contactor)
6.Defrost: N.O.10A/250VAC (applicable to 1KW load, if more it needs to connect an AC contactor)
7.Evap. Fan: N.O. 5A/250VAC
( The difference between SF-104 and SF-102:
SF-102 has the function of light and compressor, SF-104 has the function of compressor, fan and defrosting.)
