UNIQUE ELECTRONIC
CHARACTERISTICS |
Zero
crossing volt detection
|
Relays open circuit at any time of the AC sine-wave; when this
happens, the residual EMF induces a high voltage surge that destroys
starting capacitors. At turn ON, sometimes sparking weld the
contacts and the motor runs continuously until it burns.
Pumptron does not contain relays. The switching is done
electronically at the zero crossing volt of the AC so the capacitors
never receive a high surge and there are no contacts that could
weld.
“Ideal for pressure installations” |
|
CURRENT SIGNAL
CONVERTER |
A
special electronic circuit converts the current signals from the
motor in a way that always operates accurately regardless of motor
size.
“Very High Stability” |
|
ELECTRICAL ISOLATION |
The switching commands from the 12 Volts logic circuit to the high
power 240 / 415 Volts is done by an Infrared Light Beam.
“No electric contacts” – “Safe to operate” |
|
DETECTION OF MAINS
SURGES |
Discriminates between power fast surges and major voltage
fluctuations.
“No unnecessary starts and stops” |
|
REPETITIVE SWITCHING
DETECTION |
If a pressure switch becomes faulty and causes repetitive switching,
Pumptron stops the pump and passes the command to the water recovery
timer. When time lapses it starts again but it stops if the
condition persists.
“Lack of water indicates the fault” |
|
STARTING PEAK CURRENT
DETECTOR |
If at start the initial peak current has increased from the normal
level, Pumptron reports overload and stays standby.
“Indication of sediments or iron oxide accumulation ” |
