Explanation of Parameters and their Significance
|
|
kVdc
|
70
|
55
|
This is the average value of the power supply's rated output voltage waveform. Maximizing this value increases ESP collection efficiency

|
|
|
Peak kV
|
78.2 (no load)
71.8 (rated)
|
92.4 (no load)
70.0 (rated)
|
This is the maximum value of the power supply's rated output voltage waveform, with kV limit set at 100%.

|
% Ripple (kVp-p)
|
3-5
|
35-45
|
This is the difference between kVdc and peak kV. Minimizing % ripple means a higher kVdc (and better collection efficiency) for a given kVp.
|
|
Power Factor
|
.94
|
.63
|
This is the ratio between real power (kW) to apparent power (kVA). A higher PF means that a lower kVA is required to provide the same kW load. For a utility, this equates to more kVA to feed into the grid.
|
|
Input kVA
|
78.7
|
92.2
|
|
|
Operating frequency
|
25 kHz
|
60 Hz
|
This is the frequency (in cycles/sec) of the electrical power being supplied to the main step-up transformer. Higher frequencies translate to smaller transformers and faster control responses.
|
|
EMI filter
|
yes
|
no
|
|
|
Arc shutdown time (msec)
|
0.03
|
8.33
|
This is the time required for the power supply to extinguish power when an arc occurs. A shorter shutdown time minimizes the fault current and energy delivered to the precipitator.
|
|
Max ambient temp (deg C)
|
40
|

|
|
|
Volume envelope (ft3)/(m3)
|
24/.68
|
65/1.84
|
The smaller footprint and weight of the PowerPlus is a consequence of a much smaller transformer and integrated controls. With larger PowerPlus models, this difference becomes less pronounced.
|
|
Plan envelope (ft3)/(m3)
|
10/.28
|
21/.60
|
|
Weight (lb)/(kg)
