Climate control accessories Control/regulation Enclosure internal thermostat Especially suitable for controlling fan-and-filter units, heaters and heat exchangers, this thermostat can also be used as a signal generator for monitoring the enclosure internal temperature. Technical specifications: − Bi-metal controller as a temperature-sensitive element with thermal feedback. − Contact population: Single-pole change-over contact as a quick-break contact. − Permissible contact load: Cat. 5 – 3 (heating) AC 10 (4)1) A, DC = max. 30 W Cat. 5 – 4 (cooling) AC 5 (4)1) A, DC = max. 30 W 1) = inductive load at cos ϕ = 0.6 − Setting range: +5°C to +60°C Rated operating voltage Model No. SK 230/115/60/48/24 V (AC) 3110.000 60/48/24 V (DC) − Weight: approx. 105 g − Dimensions: 71 x 71 x 33.5 mm − Switching difference: approx. 1 K ± 0.8 K. − Flexible mounting on a vertical or horizontal 35 mm support rail to EN 50 022, and snap fastening in the TS/SE enclosure section or on the mounting plate using the supplied adaptor. Accessories: Mounting plate TS with integral top-hat rail, see page 658. Hygrostat The hygrostat switches on the heater and/or fan when a preset relative humidity in the enclosure is exceeded. In this way, the relative humidity is raised above the dew point, and condensation on assemblies or electronic components is avoided. Technical specifications: − Contact population: Single-pole change-over contact as a quick-break contact. − Permissible contact load: AC ~ 5 (0.2)1) A DC = max. 20 W 1) = inductive load at cos ϕ = 0.6 − Setting range: 50 – 100% relative humidity − Weight: approx. 100 g − Dimensions: 71 x 71 x 33.5 mm − Switching difference: approx. 4% Rated operating voltage Model No. SK 24 – 230 V (AC), 24 – 75 V (DC) 3118.000 − Flexible mounting on a vertical or horizontal 35 mm support rail to EN 50 022, and snap fastening in the TS/SE enclosure section or on the mounting plate using the supplied adaptor. Accessories: Mounting plate TS with integral top-hat rail, see page 658. Bottom-mounted adaptor for enclosure internal thermostat SK 3110.000 and hygrostat SK 3118.000 Bottom-mounted adaptor with mounting option for screwed cable glands, for targeted cable infeed from appropriate equipment such as SK fan-andfilter units and enclosure heaters. In conjunction with screwed cable glands, it is also suitable for use as strain relief. Packs of Model No. SK 1 3110.200 Control unit for EC fan-and-filter units Temperature-dependent speed control for EC fanand filter units to reduce noise and save energy. The function of the fan can also be monitored. ● Activation and monitoring of up to 4 EC fanand filter units (caution: EC fan-and-filter units cannot be controlled with speed control 3120.200!) ● Rated operating voltage: 24 V (DC) ● Top-hat rail assembly ● Temperature setting range: +5°C to +55°C/41°F to 131°F ● External temperature sensor to record the ACTUAL temperature ● Status LED to display the operating status ● Alarm relay for reporting overtemperature, fan defect, cable interruption and sensor failure For fan-and-filter units Model No. SK SK 3245.XXX 3235.440 Supply includes: NTC sensor, length 1.80 m. 476 Rittal Catalogue 33/Climate control
