ARWD

Product catalog summary
Overview: The document describes the specifications and features of single-phase, two-speed fan speed controllers, specifically the ARWD series. These controllers use an autotransformer and are equipped with a fuse for safety. They allow for switching between speed settings via CL-CL contacts, which can be controlled by an external clock.
Specifications: The controllers are designed with two knobs for programming fan speeds for different times of the day, and two indicator lights: green for power supply and red for motor thermal contact activation. The controllers include thermocontacts to prevent motor overheating, with a reset button available in the ARWD/S/R version for manual restart after thermal contact activation. They are built with Class II insulation and have protection grades of IP21 or IP54, depending on the model. The maximum ambient temperature for operation is 40°C, and they comply with the EN61558-2-13 standard.
Technical Details: The controllers operate at 230V with a frequency of 50/60Hz and offer 5-step regulation. The rated current ranges from 1.5A to 14A, with various models available to accommodate different current requirements. Dimensions and weights vary by model, with specific measurements provided for each type.
Models and Dimensions: The document lists several models, including ARWD 1.5/S, ARWD 5.0/S, ARWD 3.0/S/R/2, and others, with detailed dimensions and weights for each. The voltage levels are categorized as HIGH and LOW, with specific voltage values provided for each regulation step.
Contact Information: The manufacturer, Breve Tufvassons, is located in Łódź, Poland, with contact details provided for further inquiries.
Note: The manufacturer reserves the right to change the parameters due to ongoing development and changes in technical requirements.

ARWD-1

Single-phase two-speed fan speed controllers Rated current SEC: Rated voltage PRI: Control type: Autotransformer, single-phase, two-speed fan speed controllers equipped with a fuse. Switching between settings is done by shorting or opening CL-CL contacts, e.g. by an external clock. Regulators are equipped with two knobs, thanks to which the fan speed can be programmed, e.g. during the day and at night, and with two lights - green indicating power supply and red indicating motor thermal contact activation. Connecting thermocontacts protects the fan motor against overheating (the controller is switched off). ARWD/S/R version has a reset button for starting the regulator after the thermocontact has operated - controller does not switch on automatically. Made with Class II insulation and protection grade IP21 (ARWD 10 - 14) or IP54 (ARWD 1,5 - 7), max ambient temperature 40°C. Thermal class of insulation B (130°C). Manufactured in compliance with EN61558-2-13. Voltage level ul. Postępowa 25/27, 93-347 Łódź, Poland tel.
