Product Introduction

1. Digital Control Technology
Shanjie Electric's EPS emergency power supply strictly follows the national fire protection standard "17945-2010" and the new 2015 version of the product implementation rules for standardized productionThe central control system of EPS emergency power supply adopts efficient and digital DSP control.
All switch input, output, and analog sampling signals are optically isolated to effectively resist the influence of external interference on the systemThe control circuit is different from the traditional sampling and averaging method. The system adopts direct effective value sampling, which greatly avoids the interference of harmonics on samplingdisturb

There are no potentiometers in the control board, and parameter settings can be completed through software calibration programs, avoiding the instability and instability of traditional potentiometersThe inconvenience of user maintenance and adjustment.

2. Convenient system self-test function (microcomputer self-test type)
The control system is equipped with historical memory fault information recording and real-time data recording units. Historical records can be queried through the display, and EPS can be accessedThe real-time detection and processing of the main functional modules of the emergency power supply greatly improves system safety and reduces maintenance costs.

3. Humanized display interface
LED color digital display screen, blue background white text display screen, high display brightness, beautiful appearance, strong three-dimensional sense, can be displayed through the panelSet and adjust various parameters.LCD color touch display screen, equipped with Chinese and English display interfaces, with various operation and fault information displayed intuitively and clearly, and can be accessed through the buttons on the panelKey to set and adjust parameters

4. Powerful remote monitoring
The system provides two serial communication interfaces, RS232 or RS485, which can achieve remote monitoring. If necessary, we can provide the communication protocol for this systemIn order to seamlessly connect with your central control room monitoring software, separate monitoring software can also be provided for independent monitoring.

The remote monitoring system has powerful functions and can basically achieve all the functions that can be achieved locally, including displaying the operating statusParameter settings, data saving and browsing, etc.
