Motor Controllers Dealers in Mumbai

Libratherm offers variable speed DC drive, which is rugged, compact and fully solid-state controller designed to drive either permanent magnet DC motors or excited field DC motors with the facility to vary the speed through a single turn potentiometer or through the external analog control signal of 0 – 5VDC, 0 – 10 VDC or 4 – 20 mA. Two different models are available, one is TDM-1000, which is a modular design with optically isolated control input and other is TDM-10 which is ¼ DIN panel mounting type with speed control using front panel potentiometer. The control signal and the potentiometer are optically isolated from the armature and field voltage. This feature is useful to directly control the motor speed through PLC, PID or similar other process controllers in a closed loop control system without the need of external signal isolator.The drive is designed using the solid – state components and is available in the modular form to suit OEM’s applications. The drive is also available in the stand alone control panel along with accessories like RPM / voltmeter, current meter, Start / stop and forward / reverse logic, indicating lamps, speed potentiometer etc.The drive operates on 230 VAC. The speed regulation is achieved by armature voltage feed back or by the tachometer feed back. Several other controls and stanadard protection features are soft start, maximum speed set, minimum speed set, filed failure, overload protection, remote on / off etc.Applications :Suitable for small machines in Plastic, Packaging and Pharmaceutical industries.Areas where smooth steady and fine DC motor speed control is required.

Details : Fully solid-state design. Linear variation of speed. Suitable for 1/4 HP to 5 HP / single phase (4-wire or PMDC motors). Adjustable maximum and minimum Speed. Built in Current Limit / over Load Trip and Field Failure Protection. Control signal is optically isolated in modular design. Accepts speed control signal of (0-5) VDC, (0-10) VDC or (4-20) mA, hence suitable for machine automation. 1/4 DIN Size (TDM-10). Operates on 230VAC.
