Hygrostat - Bottom-mounted adaptor - Speed control EC

Catalogue 2014/2015

Climate control accessories Control/regulation 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 reduced 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 hysteresis: approx. 4% Rated operating voltage V, ~ Model No. 24 – 230, 1~ 12 – 75 (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. Colour: – RAL 7035 Accessories: – Mounting plate TS with integral top-hat rail, see page 617 – Bottom-mounted adaptor, see page 380 Bottom-mounted adaptor for enclosure internal thermostat 3110.000 and hygrostat 3118.000 Bottom-mounted adaptor with mounting option for screwed cable glands, for targeted cable infeed from appropriate equipment such as fan-and-filter units and enclosure heaters. In conjunction with screwed cable glands, it is also provides strain relief. Colour: – RAL 7035 Packs of Model No. 1 pc(s). 3110.200 Speed control EC Control unit Temperature-dependent speed control for EC fanand filter units to reduce noise and save energy. The status of the fan can also be monitored. ◾ Activation and monitoring of up to 4 EC fan-andfilter units (caution: EC fan-and-filter units cannot be controlled with speed control 3120.200!) ◾ Rated operating voltage: 100 – 250 V ◾ Top-hat rail assembly ◾ Temperature setting range: +5°C…+55°C/ 41°F…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 EC fan-and-filter units Model No. 3240.500/3241.500/3243.500/ 3244.500/3245.XXX 3235.440 Supply includes: – NTC sensor, length 1.80 m 380 Rittal Catalogue 34/Climate control
