Lighting Power Efficiency Control System

PowerMinistor-II adopts DVR AC-AC direct convert technology, optimizes power supply system input voltage to meet voltage demand of loads, which implements power saving and protects the loads.

Main Functions:

a. The voltage of each phase can be adjusted independently so that PowerMinistor-II can reduce the negative sequence voltage, negative sequence current, zero sequence voltage and zero sequence current which resulted from three-phase unbalanced system, as a result, the additional loss was reduced sharply.

b.  Power saving voltage levels can be set according to customers special requirement in order to achieve the maximum power saving effect.

c.  Harmonic filtering components eliminate the high-order harmonic effectively, so PowerMinistor-II reduced power line transmitting loss, at the same time, it reduced harmonic impulse on terminal power loads.

d.  PowerMinistor-II adopted high-quality magnetic materials and special construct design mode, so it can suppress transient and surge to protect terminal power equipments.

e.  PowerMinistor-II can reduce start current of building system power loads.

Technical Features

a.  Rated input voltage range: 380V-450V

b.  Phase: 3 φ

c.  Working frequency: 50Hz

d.  Insulation level: H

e.  Working temperature: 0-70

f.    Insulation resistance: ≥100 MΩ

g.   No-load power loss range(W): ≤3, Error accepted: ≤±15%

Application Scope

PowerMinistor-II is widely applied to lighting solution of factory, waterscape, hotel, restaurant, recreation places and residential area etc all kinds of lamps, for example:

Commercial lighting: supermarket, shopping center, shopping mall, hotel, restaurant, Large-size billboard, park/underground garage 24h-self-adaption lighting etc.

Factory lighting: power electric, communication, textile, paper manufacturing, mechanical electronic, petrol chemical industry, garments, food processing etc factories.
