Percept Electronics

We mfg. Resistive load banks: ac - 1ph &3ph & dc load banks as per customers reqm.

Using w/w,open type,s. S. Grids/coils etc. Type of resistive elements.

Used for testing dummy loads: d. G sets,battery discharge etc.

DYNAMIC BREAKING RESISTORS: is the simplest and most widely used method of braking a load driven through a d.c.motor as it involves no wear & tear unlike mechanical brakes. For dynamic braking, the motor armature is closed on a suitably designed Dynamic Braking Resistor(DBR),while the motor field remains energised.The kinetic energy stored in motor and load gets dissipated in the DBR and the system comes to a halt within a few seconds.
