Description

Digital Box For Three phase Motor

Application:

Digital Box For Three phase Motor widely used in deep well pump, diving pump, dredge pump, pipeline pump, pressure pump, multi-level pump etc. and used in life supply water, underground drainage, building supply water, etc.

Characteristic:

Firstly, Rated Operating Voltage: AC 380V-415V/50Hz
Secondly, Rated Output Power:0.75-15KW
Thirdly, Adopt the Digital chip control, integrate in upper/lower water level control and pressure control automatically
In conclusion, Both “One Key Automatic Setting” and “Manual Setting” for set the overload and under load
Have overload, under load (dry running), Lack-phase, over/under pressure protection
Under load restart time from 1 to 60 minute adjustable
Domestic original memory function, and easily check the last 10 failure data.
Humanization design, small volume, and convenient installation;
6 stages of processing inspection, 120 hours of dynamic trouble simulation     fully aging;

Main Specification:

Firstly, Locked-rotor Actuating Time: not more than 1.5 seconds
Secondly, Actuating Time for Dry-running Protection: not more than 20 seconds.
Local Power Loss: Static Power: 4.5W, Dynamic Power:10W.
Over-current Actuating Time: 1 seconds to 1 minute (inverse time lag     characteristic: the higher current for the shorter time).
Liquid Level Control Mode: use the pulse electrode probe to detect and its transmission distance is less than or equal to 1000 meters.
Pressure Control Mode: electro connecting pressure gauge, normal open and close type pressure switch, and floating ball liquid level switch.
