Description
WDY battery charge and discharge machine
Range of application:
Suitable for charge, discharge battery , measurement of various
lead-acid battery and alkaline battery
Working Principle:
The device adopt advanced double closed loops PID feedback control
technology, to commutate toward working voltage and current of
charge and discharge machine
MIcro controller give voltage and curent signals according to
program set and calculate compare with DC side voltage and current
signal that close loop system feedback
By regulating circuit, it controls touching pulse output by phase
shift chip to arouse thyristor to commutate as well as change
electricity charge and discharge by contactor.
When the machine is on work, system can timely feedback voltage and
current signals of DC side. one hand, comparing to set point it
automatically regulate to make set point keep accordance with
voltage/current parameters, another hand, it transmit these
signals to micro controller and display the actual numbers timely
on the LCD board by calculation
Performance and characteristic
Energy saving: adopting active contravariant to feed back energy of
battery into power network when it discharge , so the energy loss
will be greatly reduced
Practicability; several modes of charging and discharging. It
automatically change for different section by time, power capacity
,voltage.
Safety: Complete protection function for both software and
hardware. also had malfunction protection of over/lower voltage,
current cut, over/lower current, over heat
Micro-computer control, Host computer contorl system, Power off
protection function, Data collection, Date-processing, Stable
performance
