跑步机专用滤波器
1． vv系列:
v v系列多功能电源线rfi滤波器，用于辐射控制及大噪声工业环境。
v v系列电源滤波器能保护设备不会因来自线上传导干扰、特别是线对线噪声干扰以及瞬态值而失效。它们还能必需的噪声抑制，使大多数设备能够满足fcc的传导辐射规范。
v v系列电源滤波器，通过ul、vde、csa安规认证.

备注:
1) 在进行耐压测试试验中，泄漏电流的设置应在限值10ma的档位上；电压应以不超过150v/s的速度缓慢升压到试验电压，试验时间应从达到试验电压起60s。
in the anti-voltage test, leak electric current should be settled at 10ma, and voltage should be arrived slowly under 150v/s before it reaches to the test voltage,the test time also should start 60 later when it strikes the test voltage.
2) 上表中插入损耗的参数是在50ω电路中的测试数据。
the loss parameter in above chart is the testing data of 50ω.
3) 地与线间绝缘电阻最小值为6000mω。
the smallest insulation resistance between the ground and line is 6000mω
