Features
1. High-performance compact syncronous motor The accurately turning motor is employed to provide for longer period of measurement. 2. Common for 50/60 Hz power frequency A lever is used to select 50 Hz or 60 Hz. There is no need to rearrange the control panel and other signal destinations. 3. Dimensions as per DIN 43700 standard The units are in the 48 × 48 DIN standard size. They can be fitted in panels and give refined metallic appearance. 4. Easier wiring The flat terminals (#187) are quick and easy to connect. 5. Rotary indicator The rotary indicator makes one turn every 2 minutes for monitoring. 6. Compliant with UL, CSA and CE.
Typical applications
Maintenance management of machine tools, automated machines, control panels, forming machines, medical equipment, generators, compressors, water treatment facilities, presses, motors, etc.
