Climate control accessories Control/regulation Speed control Temperature-dependent speed control for TopTherm fan-and-filter units and air/air heat exchangers for noise reduction and to save energy in part-load operation. Technical specifications: − For mounting on a 35 mm support rail DIN EN 50 022 − Dimensions (W x H x D): 105 x 90.5 x 60.2 mm − Rated operating voltage: 100 – 230 V (AC) − Setting range: +20°C to +55°C − Phase cross-over with microcontroller − Maximum fan output 300 W or 2 A Packs of Model No. SK 1 3120.200 Supply includes: − Speed control − NTC sensor, length 1.80 m. Note: Only suitable for use with 1-phase AC motors and equipment. Accessories: Mounting plate TS with integral top-hat rail, see page 658. Interface board for equipment with e-Comfort controller The interface board is an extension for equipment with e-Comfort controller. In this way it is possible, e.g. to monitor a master/slave combination of up to 10 cooling units in conjunction with a Rittal CMC III. Control is achieved via standardised interfaces: RS232 (DB9) or RS485, one PLC interface (DB9). RS422 (RJ 45 jack) is the connection to the Rittal CMC III. In this way, remote monitoring via TCP-IP, graphical interfaces for operation, evaluation and control, documentation, and connection to additional sensors for access control are possible. The extension board is built into a 1 U plastic housing. A voltage supply of 24 V (DC) is required. This may be supplied from the CMC III via a wide-range power pack DK 7320.425 (100 to 240 V (AC), 50/60 Hz) or externally via a Kycon connector. Packs of Model No. SK 1 3124.200 Supply includes: − Interface board integrated into a plastic box W x H x D (mm): 136 x 44 (1 U) x 129 − Serial SUB-D cable, 1.5 m. Note: Networking and monitoring plan may be found on the relevant product page on the Internet, under “Download”. 35C 30C 25C 20C 20C 40C 35C SK BUS system The SK bus system facilitates communications between several enclosure cooling units and air/ water heat exchangers .500/.510/.540/.600/.610/ .640. via a master/slave construction such as that required e.g. in complex bayed enclosure systems for optimum operating conditions. Technical specifications: The master/slave construction facilitates common activation and deactivation via door limit switches, parallel activation and deactivation via a temperature setpoint, and common collective fault signals and temperature logging, thereby eliminating the need for intricate wiring. Packs of Model No. SK 1 3124.100 Supply includes: − 3 m shielded interface cable − Operating instructions on programming the cooling units. Note: − nB = nK – 1 − nB: Number of order units (SK bus system) − nK: Number of cooling units to be linked Networking and monitoring plan may be found on the relevant product page on the Internet, under “Download”. Master/slave adaptor for Thermoelectric Cooler Parallel operation of up to 5 thermoelectric coolers to increase cooling output or for redundant use. For units Model No. SK SK 3201.200, SK 3201.300 3201.070 Also required: Per slave 1 x RJ 45 network cable DK 7320.470 or DK 7320.472, see page 786. Rittal Catalogue 33/Climate control 477
