2 PowaTRIM, what does it do? Reduces kvah, kwh & Cost Corrects Power Factor Reduces Total Current Content, inc Harmonics Protects Against Surges & Spikes

3 PowaTRIM, what does 1 module save? 8-13 kva per hour, per module 11, a year 218 a month a week 0.13/kVAh, 10kVA generated per module, 24 x 7 operation

4 PowaTRIM, planning a deployment. 150A of Load per PowaTRIM Module. A PowaTRIM module will convert 25kVAr into 8-13 kva. Multiple PowaTRIM modules can be deployed in any location PowaTRIM normally results in a 6-12% reduction in site kva demand.

5 PowaTRIM, what are it s features?

PowaTRIM, how does work? The out-of-phase component of your power supplies no useable energy but you still pay for it. PowaTRIM reduces power/costs in 2 key ways: 1.

6 PowaTRIM, how does work? The out-of-phase component of your power supplies no useable energy but you still pay for it. PowaTRIM reduces power/costs in 2 key ways: 1. The main savings method of PowaTRIM is the ability to reclaim a negative current from adjacent phases (such as phase B-C and C-A into phase B). This current is inserted into each phase by means of inducing currents through magnetic coupling of the other phases. Devices as a choke coil or current transformer are used, and by wrapping the coils in such a way so as to produce a negative current with a relatively large 120 cycle content. The net result is a reduction in power consumption between 7 to 12% depending on load type. 2. PowaTRIM creates a leading power factor of at least 50% leading which reduces the inductive VAR s on your grid by up to 40 kvar per module. The resultant reduction in line current means lower conductor and transformer losses. This could mean a 1% to 2% improvement in losses. In summary: PowaTRIM returns out-of-phase power into your electrical grid. PowaTRIM does this without consuming energy. It uses the inductive power you re already consuming and re-introduces this surplus power onto the adjacent phases.
