Advantages and Features of EPS Emergency Power Supplies

Advantages and Features of EPS Emergency Power Supplies

EPS emergency power supplies can be regarded as an emerging industry that has experienced rapid growth only in the past two years. Compared with the well-established UPS technology, EPS systems share some similarities but also exhibit key differences. The commonality lies in their ability to continue supplying AC power to the load during utility power failures (outages), and both technologies employ IGBT inverter technology and pulse-width modulation (PWM) techniques.

How long does the EPS emergency power supply provide power?

How long does the EPS emergency power supply provide power?

The duration of continuous power supply provided by an EPS emergency power supply shall be determined on a case-by-case basis. According to the national standard GB 17945-2010, “Fire Emergency Lighting and Evacuation Direction Systems,” when the mains power is interrupted, the EPS emergency power supply must provide continuous power for no less than 90 minutes. This requirement not only ensures adequate emergency lighting during fire-related evacuations but also meets the lighting needs of firefighters during rescue operations.

UPS Fault Analysis and Maintenance Methods

UPS Fault Analysis and Maintenance Methods

I. First, check the UPS insulation. In the EPS2000, the DC ground of the module section is floating and electrically isolated from the frame; therefore, the insulation between the module and the frame must be carefully considered, as a potential difference of several tens of volts typically exists between them. II. Second, read the fault alarm information displayed on the UPS monitor. III. Zero-voltage reference point
