MTC-20/2S User Manual_______________________________________________________________________________________________________________(15) EXT. SENSOR 1mV/°C connectorBNC connector to connect external thermometer with a voltage output of 1mV/°C(see (14)).(16) SENSOR B connector8-pole connector for temperature SENSOR B.This connector also provides the POWER OUTPUT (18 / 19) for the heating unit(max. 12V DC and 1A) for devices with the ALA DIN connector cable assembly.(e.g. HPT-2A, see www.alascience.com).(17) OUTPUT B 10mV/°C connectorBNC connector monitoring the temperature determined by SENSOR B (16),sensitivity: 10mV / °C.(18) / (19) POWER OUTPUT Max. 1A DC connectorsBanana jack connectors for the heating unit. This output supplies amaximum voltage of 12V DC and a maximum current of 1 A.POWER OUTPUT is also available at the SENSOR A (13) and SENSOR Bconnectors (16) for devices with the ALA DIN cable assembly.3.3. Rear Panel ElementsPOWER: The PWR switch turns on/off the power supply (115/ 230 V AC, max. 50 W). Theselector for the line voltage and the connector for the power cord are located on the rear panelof the instrument.FUSE: Line fuse: 0.8 A slow (115 V) or 0.4 A slow (230 V). It must be replaced only byspecified type. Please disconnect mains power plug when replacing fuse.Caution: The instrument may be damaged if the wrong line fuse is installed e.g. 0.4 A if theMTC-20/2S is operated at 115 V!___________________________________________________________________________version 2.7 page 8
