¡¡¡¡WDFZ-5(5A) Large
Power Intelligent Transmitter
WDZ-5A Rectification Power
¡¡The new generation DC IP transmitter system is composed of WDZ-5A
rectification power (contained balanced load controller) and WDFZ-5
large power intelligent transmitter. This system breaks through
the conventional design mode; uses chip microcomputer for controlling,
and is driven by intelligent IGBT. It has high measurement accuracy,
multi functions and high dependability. It is small and light,
and can be carried conveniently. It also has the perfect function
of the over-voltage, over-current, open circuit protection and
personal safety protection and so on..
Features and functions:
- The rectification power and transmitter uses detachable
design, and the bottom of the rectification power box is installed
with the versatile wheel, so that it is convenient to carry.
- It can automatically save current values for late processing.
- Chip microcomputer control, timing accurately, and high
reliability.
- Large screen display, Chinese character menu.
- Digital display of the output voltage and current.
- It can measure the earth resistance between the two injection
current electrodes.
- Light diode shows the function mode and the fault conditions.
- Super protection function:
220V input power supply low-voltage protection.
Output voltage, over-voltage protection.
Balanced load open circuit display, over-current protection.
Power supply circuit, over-current protection.
It uses high voltage plug in connector at high voltage connecting
position to improve the personal safety protection.
- WDFZ-5A large power intelligent transmitter has not only
the function of all transmitter of WDFZ-5A model transmitter,
but also all the function of WDJD-3 digital DC IP equipment.
