A huge manufacturing & testing facility is backed by dedicated work force, committed to strict quality control and constant R & D.

Here is some valuable bio-data revealing more working details about AC & DC solenoids which will also help you in selecting the right type for your exact requirement, though in most of the cases it is predetermined. AC solenoid tends to be more powerful on lower stroke than DC. At the cost of ‘Inrush Current’ which at maximum stroke can more that ten times the closed current. Complete closing is essential to bring this current down to normal. DC solenoid takes the same current throughout the stroke and does not overheat even it sometimes incomplete closing occurs by chance. AC operations is usually faster as compared to DC but even then depends on variations in response time in energizing the solenoids.

Solenoid coil assembly is more robust as it uses thicker wire, voltage limits (high and low) depends on the size of the solenoids and its rating.

Rubber magnet With aluminum casting box complete with tie rod, rubber sleeve for dust sealing etc. at extra cost according to the requirements.

A low voltage coil tends to give more power than the one of high voltage and is more robust as it uses thicker wire, voltage limits (high and low) depends on the size of the solenoids and its rating. A solenoid can be wound for any voltage but even then in general high voltages on the smallest solenoid and very low voltage on the larger AC solenoid are both to be avoided. A good AC solenoid if correctly used should be quite when closed, but it has fundamental tendency to produce hum and can be overcome by correct design and accurate assembly. Dirt on the mating faces or mechanical over load, may also make it noisy DC solenoid is fundamentally quiet. DC solenoids are often used on rectified AC which may be either full wave or smooth half wave. In either cases, the value of capacitor across the DC output will affect the voltage and it is important that the solenoid should be wound for the on-load voltage of the power as a whole.

Magnet coils when passing current is always over ambient room temperature (specifically more whenever a solenoid is enclosed) so care has to be taken in designing and reference temperature is to be taken as 75 Centigrade where as ambient temperature is about 30 Centigrade.

Input line reactors is used as a Line Voltage Buffer to Protect the Drive From Line Transient & Spikes. it also Lower Harmonic Level to the Supply Line.

High current choke on the output side of inverter can reduce rapid voltage rise ratio and hence protect the motor.A motor choke is required to reduce unacceptably high voltage peaks caused by cable voltage reflections and these also have a steep dvdt.

Electromagnetic coils A low voltage coil tends to give more power than the one of high voltage and is more robust as it uses thicker wire,

The temperature of the coil when passing current is always over ambient room temperature (specifically more whenever a solenoid is enclosed) so care has to be taken in designing and reference temperature is to be taken as 75 Centigrade where as ambient temperature is about 30 Centigrade. In this way the adequate margin is maintained from safety point of view.
