What are the common problems of EPS power supply
EPS emergency power supply is a power supply equipment composed according to the needs of first-level load power supply equipment such as fire fighting facilities, emergency lighting, accident lighting, etc. In daily maintenance and management, EPS emergency power supply often has the following problems:
(a) output circuit due to greatly overloading caused by the output circuit breaker jump;
(b) Due to the quality of the circuit breaker in the output circuit serious overload or short circuit when the jump and not disconnected, resulting in EPS emergency power internal failure;
(C) EPS emergency power charging board failure or EPS battery quality problems;
(4) The output loop is overloaded to 120%-140% under normal mains conditions. If the circuit breaker does not jump, the EPS inverter cannot switch power supply when the mains power is cut off.
(5) EPS emergency power supply front end is not equipped with lightning protection device, in the thunderstorm season EPS is damaged by lightning;
(6) The operator frequently operates the forced start function of the EPS emergency power supply, and the discharge depth of the battery is too large, thus damaging the battery.
(7) The air is humid in spring and summer (especially in the basement), which causes condensation on the internal control circuit board of the EPS emergency power supply, causing EPS control failures.
