FREQUENCY CONVERTER Designed for process ventilation The SFC frequency converter is designed for variable speed control of e.g. fans. This provides optimal operating economy and the lowest possible noise level. Depending on the number of work stations in operation, the SFC (along with the ST 300 pressure sensor) varies the fan speed and thus evacuates the correct amount of air. Alternatively, manual variable control can be used with the SFC PS potentiometer. The SFC VSS is used if a 2-step control is preferred. Interference filters are included. The enclosure class is IP 20 for built-in...

SFC PS POTENTIOMETER The SFC PS is a potentiometer for a variable regulation of fan speed via frequency converters. Dimensions Resistance SFC VSS ROTARY SWITCH The SFC POT is a rotary switch for 2-step regulation of fan speeds via frequency converters. Dimensions Increments SFC SB SWITCH The SFC SB is a switch for start/stop of fans via frequency converters. Dimensions Enclosure class Power supply ST 300 PRESSURE SENSOR The ST 300 maintains constant negative pressure in the discharge duct via a frequency converter that controls fan speeds. The ST 300 always provides the correct flow,...

S 400 S 400 CONTROL UNIT The S 400 is used for automatic control of damper motor SAS 24 at terminals 1–4. Fans are normally controlled via the S 600 transformer units. The after-run time for evacuation of remaining gases is built into the control unit. The time is set between 0–15 min. The S 400 is supplied with 24 VAC from the S 600 transformer unit. Dimensions Enclosure class Primary side Secondary side ACCESSORIES SMT 60 The SMT mechanical timer switch is a manual timer, adjustable from 0 to 60 minutes. The SMT 60 is wall- mounted close to the extractor. Size: 100x100x67 mm, time: 0 - 60...

S 600 S 600 TRANSFORMER UNIT The S 600 is used to supply 24 VAC to the S 400 control unit. Control of fan is made via external contactor 230 VAC, via signal from terminals 1 & 2. Frequency converter is controlled via the potential-free outputs, terminals 3 and 4. Dimensions Enclosure class Primary side Secondary side 230 V~ Main connection. 230 V~ Connection SKO. Potential-free VX-switch. 24 V~ Votage. Switch connection.

The S 200/230 is used for automatic control of damper motor SAS 230 and/or a fan. The after-run time for evacuation of remaining gases is built into the pliers sensor (~30 sec.). For longer after-run times, there is an adjustable timer card (0–15 min. and 0–240 min.) available as an accessory. Single-phase fans (max. 0.75 kW) can be directly controlled via an integrated relay. Other fans are controlled with an external contactor via the same integrated relay, terminals 1–5. Frequency converters are controlled via the potential-free output, terminals 6–8. The S 200/24 is used for automatic...
