Designed for industrial applications. • It does not incorporate feedback. INTRODUCTION Single quadrant DC drive. Regulation is controlled by a 47kΩ potentiometer with the equipment. Output voltage varies 0-100% by the pulse-width modulation PWM. The equipment integrates a control card and a power MOS-FET technique supply for power charge. The transitor is highly efficient which makes the equipment ideal for industrial applications where the current supplied to the charge must be controlled with accuracy. APPLICATIONS The VT can be employed in any DC motor, for of electro-magnets supply, electro-valves, resistances, lamps or any AC charge in which power control is required. WORKING The equipment is supplied with 12 Vac/dc without polarity by the terminals 9-10 or 13-14 according to model. In the terminals 7-8 or 11-12 according to model charge wished to supply is connected taking into account that terminals 7 and 11 correspond to negative in the output voltage. Potentiometer of regulation is connected in the terminals 1-2-3 and the wire shield (the wire has to be shielded if the distance is up to 30 cm) in the terminal 4. Turning the potentiometer, output voltage varies by PWM with a high precision in the average value applied to the charge. This output incorporates a short-circuit protection adjustable with an inner potentiometer. The equipment has the possibility of inhibiting its working by a contact between bornes 5-6.
