TW3000A Chinese Mini Microcomputer Constant Pressure Water Supply Controller

After years of field use and user feedback, the TW controller has evolved with the following practical features:

Online parameter adjustment is convenient, especially the ability to set pressure using only the plus and minus keys, providing great convenience for both manufacturers and users.

The set pressure and actual pressure are displayed with three-digit accuracy, thereby improving the display and control precision for 1.6Mpa and 2.5Mpa remote pressure gauges. In high-rise water supply and special applications, this offers added convenience.

It supports both switching power supply and linear power supply. The switching power supply has strong anti-interference capability and a wide voltage range, making it particularly suitable for rural power grids.

A complete range of models is available, including six soft-start models with Chinese character LCD display, facilitating selection for special applications.

Comprehensive alarm functions include inverter failure, remote gauge wire break or short circuit, undervoltage timeout, and water level alarm indication.

Password-controlled timed shutdown provides convenience in handling specific issues.

Programmable three-stage time-controlled start/stop (three starts and three stops) and time-based pressure adjustment (six pressure levels) (T option).

Features small flow shutdown (i.e., sleep mode), offering convenience in energy-saving applications with specific requirements.
