TCW Torque ControllerProducts

• Microprocessor used : 89C55WD (8 bit)
• Clock Frequency : 12 Mhz
• Programme Memory : built in
• Real Power Measurement upto : 2 KW
• Voltage, Current sampling rate : 50 times/sec.

Features

• Fully Solid State Design - no moving parts - no wear and tear of parts - no noise - consequently long life.
• Uses one main circuit board for easy maintenance.
• Uses the latest micro-controller chip for control functions.
• Accurately calibrated digital torque settings with a resolution of 1 watt makes torque settings accurate and can be easily reproduced for identical results.
• Soft start has been provided for all drives. This feature reduces starting currents in the drive. As a result, life of carbon brushes & drive increases.
• Connected drive is automatically recognised & indicated by means of LED on the torque controller.
• Torque setting arranged in four different ranges to suit four different drives. Appropriate wattage range is automatically selected for the connected drive, hence drives can not be abused or overused.
• Actual drive wattage (torque) is displayed. Set wattage (torque), drive current and line voltage can be seen by press of a button.
• Trip time adjustable from ( 0.1 sec to 10 secs. )
• Adjustable reverse time from ( 1 sec to 100 secs.)
• Pause time (time interval between cycles) adjustable from ( 1 sec to 100 secs.)
• Manual reverse by push button, in case of emergency.
• Drive Speed adjustable in reverse rotation.
• Hand (trigger) mode or foot switch mode, both are available.
• Expansions can be carried out either in single cycle mode or auto repeat mode.
• LED indicators provided for forward, reverse & trip conditions of drive.
• MCB has been provided to protect the controller and drives against over current by short circuits.
• Plug in type of PCBs reduce down time to minimum during trouble shooting.
• All the spares inside the panel viz : PCBs, Transformers, CT, Relays DPM etc. can be replaced by use of only a screw driver.
• Superior SCR technology has been incorporated rather than triacs. SCRS have much better voltage, current & dv/dt ratings than triacs. This leads to greater reliability & the power circuit becomes almost failsafe.
• Powermaster has over 1000 TCW Torque Controllers in active use worldwide since its inception in year 2000.
