Description:

3.7-inch bright LCD display
The Powtech inverter micro-computer controller of constant-pressure water supply, total height compact, easy to operate, sleek, 3.7-inch LCD screen, text displayed, instructions for full, rich and perfect word balloon, pumping station managers without the complexity of training in General, also mastered the operation, without the need for professional engineers to its operations. For installation and commissioning personnel, telephone communication for handling general failures, saving time and operation easier. At the same time, microcomputer water supply with constant pressure controller can be clearly shown on the display to its frequency, frequency conversion, the conversion service. LCD parameter display, set at a glance, special set up dealer service phone (user adjustable), facilitate communication fault-related issues as soon as possible.

One drive control four main pumps and a secondary pump
The Powtech inverter PC constant pressure water supply controller, and adaptable to the various internal and external pressure sensor and converter match, use range. The maximum control range 4 large pumps, 1 small pump (4 + 1). Switch output all the relay outputs that can be direct-drive contactors. Analog and switch, all with opto-isolated, anti-interference capability, with a view to enhancing the comprehensive electromagnetic compatibility. Adaptable for use with various internal and external pressure sensor and converter match, use wide range. password feature (parameter set a password before you can set), security settings, in order to prevent false alarms to be attended to. While you can do timed shut-down function, time to accumulate.

Failure query function no water alarm
The Powtech inverter PC constant pressure water supply controller, with the query function, you can confirm that the latest time of the alarm, and the time in seconds to record 10, fault information, facilitate the understanding controllers, the operation of the system. Details of the failure to repair of the system is extremely simple, easy, and engineering staff through the information it is clear that the understanding fault handling, fast to targeted programs. No water in the water tank warning shut-down features to protect water pump. Date and Time Setting functions, convenient record various failure conditions of the time for query searches. The Fuzzy control theory, Automatic Optimization of Parameters, it is simple and convenient to operate, fast response, high precision, and switching pumps, the net pressure shock.

Timing for pump changing function , increase water pump life
The Powtech inverter PC constant pressure water supply controller, a timer switch pump feature to prevent the pump run time is too long, and can be used to pinpoint a specific time, the scientific distribution pump running hours and records, improve water pump life. Available in two power-saving modes: sleep function and the small pump features. Sleep function to the unit on a daily basis with the zero flow interval automatically stops pump, and based on the specific needs to start, intermittent water supply, energy savings, the small pump features can resolve the water volume hours of emergency, save start the pump power. Ultra-high pressure, water, and pressure signal, the anti-burglary, such as pressure auto-detect feature, according to the actual situation automatically stop pump operation to avoid burglary and damage to the equipment, and is completely stable.

RS485 the centralized control
The Powtech inverter PC constant pressure water supply controller, you can RSA 85 interface with the connection (optional). Professional remote monitoring PC platform, from the computer terminal real-time monitoring, pump group to run, and the time pressure, frequency other parameters, record system to run the v
