Arc Voltage
This curve gives the peak arc voltage,
U
L
, which may appear across the fuse
during its operation as a function of the
applied working voltage, E

, (RMS) at a
power factor of 15%.

Electrical Characteristics
Total Clearing I

t
The total clearing I
2
t at rated voltage and
at power factor of 15% are given in the
electrical characteristics. For other volt-
ages, the clearing I
2
t is found by multi-
plying by correction factor, K, given as
a function of applied working voltage,
E
g
, (RMS).

Power Losses
Watts loss at rated current is given in
the electrical characteristics. The curve
allows the calculation of the power
losses at load currents lower than the
rated current. The correction factor, K
p
,
is given as a function of the RMS load
current, I
b
, in % of the rated current .

目前我们的救援机器人的上下层通讯用的是CAN总线的方式，那么what is CAN zongxian？ 它又有什么特点呢？
1、什么是CAN总线
介绍CAN总线之前我们先来介绍下什么是总线吧：总线将分散的有通信能力的测量控制设备作为网络节点，连接成能相互沟通信息，共同完成自控任务的控制网络。就像这样
简单说，现场总线就是以数字通信替代了传统4-20mA 模拟信号 及普通开关量信...[详细]
