The machine uses current most advanced MCU RISC as the integrated intelligent control unit, whose built-in PID adjuster adopting large-inertia anti-interference anti-vibration parameter design can farthest decrease the voltage and realize high-precision voltage regulation while guaranteeing various lamps working normally. Especially its particular limiting-angle function, which can full-automatically detect running condition of the load and present the best output voltage, thoroughly changes the condition that other power savers are not suitable for sodium lamp loads with single-lamp resistance compensation and completely avoid the flickering, vibration, difficult restarting and other events that often occur to these lamps. The digital display screen is visual and clear, the output voltage set is simple, and the three phase can be set and automatically controlled individually.

Used matching with JMW-K street lamp controller, it can realize turning on/off lamps full automatically without manual set termly, and it can also realize turn off some lamps automatically at midnight so as to farthest save the power. Under proper design, its integrated power-saving rate can be up to over 30% and the service life of the lamp can be prolonged twice of before. The machine is featured of reliable running, long service life and only 20%-30% of the price of electromagnetism balance type. Generally the cost can be recovered in three months.

Main characteristics: soft starting, automatic limiting voltage and saving power, stable voltage, three-phase set and automatic voltage regulation individually, positive/negative wave balance protection, output voltage automatic adaptation when starting, direct access to the connection when at low voltage, electronic limiting flow, overload protection and so on, and S485 communication interface can be equipped according to requirement.

Example of Power-Saving Calculation

Suppose the power supply V1=250V，output voltage is set to 210V，power expenditure W=UIT=U² T/R, in which W：power consumption； I：current； T：light time； R：load resistance, then the integrated power-saving rate η =（W1-W2）/W1*100%=29.4% , if using intelligent switch to turn off half loads at midnight, the power-saving rate can be up to over 45%.
