Product Overview
SHK series pump control cabinet is well-designed product, of which electrical components from international and domestic brand-name to ensure product quality, on basic of experience of pump control applications for many years, with reference to international and domestic standards, and constantly improve optimization.
SHK series of electrical control cabinet according to the different needs and occasions, set liquid-level control, pressure control, temperature control, time control, air conditioning control, special fire control, with manual and automatic start and stop function, also with protection function of overload, short circuit, phase, overcurrent and stator windings pump leaks and overheating,meantime with function of starting standby pump automatically when main pump faults..
SHK series of electrical control cabinet is reliable, durable, perfect companion of various types of pumps. This product is widely used in agricultural production, urban water supply and drainage, residential district water supply, fire protection, automatic spray pressurized circulating pump and HVAC control and boiler feed pumps and other occasions, but also applies to other types of AC motor control.

Technical indicators and operation conditions
The main technical indicators
 Liquid-level control accuracy: ± 0.*2M
 Pressure regulation accuracy: ± 0.*1MPa
 Control motor power: 0.*7 ~ **5KW
Equipment operation conditions
 A. Power supply voltage fluctuation range: ± *0%
 B. Ambient temperature: **0 ℃ ~ **0 ℃, within *4 hours, the average does not exceed **5 ℃
 C. Air relative humidity *0% to *0%
 D. Altitude: ≤ ***0 m * An altitude of over ***0 meters should be derated

Functional advantages
1.High-efficient & energy-saving: As a result of constant pressure variable, variable transformer supply system, the pump is always working in the best energy-saving state, means to increase the output power when large water consumption, and to reduce the output power when small water consumption, the output power can be automatically adjusted by water consumption. Also, due to the pump flow and speed is proportional, and be 3 party between speed and power, it is a significant power-saving. Energy consumption can be reduced to *1.2% when the flow drops to *0% (*0% rated pump).
2.Stable and reliable operation and high degree of automation: core components of special controller for water supply, converter of good quality, mature technology, high stability, be adapt to harsh working environment. Unmanned operation can be achieved, which will help manage.
3. System is running with low noise, stable pressure and high control accuracy.
4.Equipment integrated variety of protection functions: over-current, over-voltage, overload, phase loss, stall, phase unbalance power, water and other water protection.
5. Multiple pumps alternately can be recycled to run: balancing the average working hours of multiple pumps, to avoid of pump corrosion and stuck. 
6. Prolong life: soft-start of multiple pumps to reduce wear and tear on machinery and equipment instant consumption.
