Our Improvement upon Your Support
Note: Plea make sure to examine the following items before power-on:
* Reliable grounding of device enclosure.
* Power supply of the device is AC or DC and 240V.
杨志成(If 110V power supply is required, it shall be indicated during ordering.)
* Default of device input is passive contact input.
攻心为上(If active contact input of DC 240V is required, it shall be indicated during ordering.)
晋朝多少年历史* Default of the device is without anti-bouncer function
(If product with anti-trip function is required, it shall be indicated during ordering.)
* Correct polarity of current input as well as correct pha quence of voltage input
* During on-site debugging, power-on time of high current shall not be too long (For this device, conti
nuous running is available when current in the AC current circuit is twice of the rated current, 10s running is allowable under ten times of the rated current and 1s running is allowable under 40 times of the rated current.), so as to avoid unnecessary damage.

1. General
Taking various high and new technologies such as computer technology, electric power automation, communication technology, etc., and integrating protection, measurement, control, monitoring and communication into one, YZ201/301 ries integrated microcomputer protection device is a new type
of electric product, a basic hardware device to realize the automation of electric power system, as well as an ideal component to replace the traditional relay protection and to constitute the intelligent switch cabinet. A varieties of highly integrated functions, flexible tting, completely Chine-localized display technology and friendly human-computer interface enable the YZ201/301 ries integrated microcomputer protection device to be the main protection or back-up protection for various electric equipment and circuits with the grid below 10KV in the
electric power system. And YZ201/301 ries integrated microcomputer protection device
is not only applicable to all kinds of middle-voltage grids (ungrounded grids, resistance
grounding, arc suppression coil grounding and direct grounding grids), but to various
switch cabinets as well as systems of various connection ways such as single bus, double
bus, bypass bus and double inlet wire power supply system.
