How does the small power load select the EPS type?

Firstly, the load nature and quantity are determined: single phase power supply or three-phase power supply, which is pure impedance load or weak sensibility, or strong inductive load and quantity; Load is single phase and number can choose type EPS single-phase lighting, also can choose type three-phase EPS, if single phase load is a single alone, should choose type EPS single-phase lighting, if there are both single-phase and three-phase mixing in the load only choose type three-phase EPS; A three-phase EPS can only be used if the load is three phases. 

 

How to calculate the capacity of lighting or mixed EPS for emergency lighting? 

 

The series EPS is used for emergency lighting load: when the load is electronic ballast fluorescent lamp, EPS capacity calculation method: EPS capacity = electronic ballast fluorescent lamp power total x 1.1 times. 

 

When the load is a fluorescent lamp of inductive ballast, the calculation method of EPS capacity: EPS capacity = inductance ballast fluorescent lamp power sum x 1.5 times. 

 

When load is metal halogen lamp or metal sodium lamp, EPS capacity calculation method: EPS capacity = metal halogen lamp or metal sodium lamp power total x 1.6 times. (note: because when JHE series EPS emergency power supply is single-phase output circuit, there is no partial phase, and JHE - H.D series of EPS is three-phase output, while phase can run, but the output power of each phase for EPS only 1/3 of the nominal capacity, not too many partial phase.
