| Parameter |
Digital Pump Manager |
Conventinal Control Panel |
| Over Load |
| Micro-controller Based Overload |
- Trips instantly at set current
- very long life since no heating element
|
|
| Extra Thermal Overload Relay |
- Extra Overload has to be added
- Tripping time depends on current. As current increases, time reduces
- Wear and tear due to continuous heating
|
|
| Under Current |
| Inbuilt under current sensor |
|
Inbuilt under current sensor |
|
| Extra Electronic Unit |
|
An extra electronic circuitry needs to be added to the panel |
|
| Ampere Meter |
| Inbuilt - Digital |
|
Inbuilt Digital Ampere meter which can show difference of even 100mA |
|
| Extra Moving Coil Meter |
|
Extra Ampere meter has to be added |
|
| Single Phasing Preventer |
| Voltage as well as Current based SPP |
|
Motor current gets affected when motor is not getting right voltage so any problem in supply line is sensed and motor is saved. |
|
| Voltage Based SPP |
|
Line voltage reaching the panel but not reaching the motor, this can not be sensed by voltage based SPP and so motor may burn. |
|
| Dry Run Protection |
| Inbuilt Dry Run Sensor |
|
Pump running dry is automatically sensed without the use of external liquid or flow sensor |
|
| Extra electronic unit |
|
Conventionally not included and they depend on the mechanical water or flow sensors. |
|
| Fault Finding |
| Digital Display of Faults |
|
Direct reading of Fault on display. Hence easy and reliable fault location and removal |
|
| No or premitive fault indication |
|
Fault finding is difficult and tedious |
|
| Maintenance |
| Less components, Less wiring, latest technology |
|
Less number of components and less wiring means fewer maintenance issues, latest plug-in design makes it easy to change cards / parts and hence very less down time. |
|
| Lots of wiring and complex wiring inside |
|
More components and wiring means frequent maintenance requirements. Not easy to replace any part. |
|
| Reliability |
| Latest Micro-controller Technology |
|
Highly reliable due to use of low voltage micro-controller control card and the use of best quality material. |
|
| Analog components |
|
Limited reliability because reduced accuracy of analog components. |
