China mine top 10 well-known brands Hunan Futenma Bryant special mine Technology Co., Ltd. Lightning product categories and sub-power signal type, the power of parallel and series, the signal is divided into categories: computer network type, type video, audio category, feeder category. Provide examples of this power is KBT-380A/80 Three-phase power supply box mine Their product categories: three-phase power supply box mine Model Specifications: KBT-380A/80 Features: 1. Fast response time: 25 us in the fast response time, the power lines on the overvoltage been effectively curbed, while the discharge energy, lightning automatically return to normal after the state (high impedance state); 2. Protection circuit: When mine components lightning damage or deterioration, the live circuit automatically from the phase At the same time, first-light (red), and the other circuit to continue their normal work; 3. Use clamp technology: To ensure that the user is safe, reliable power supply, application of new clamp technology, or when the system failure for mine action, to ensure that the potential difference between the lines remain unchanged; 4. With the internal temperature, current limit, and thoroughly to avoid the fire. 5 shows the working status: mine on the light box panels, instructions for the work of the state mine, said mine green light for work to normal, red-liang said that the phase-mine has been unable to work and need repair. 6. Flow capacity. 7. Installation simple, convenient, no special maintenance. Technical parameters: Model KBT-380A/80 Voltage 380 Application of the AC power system Flow capacity 80KA (8/20us) Continuous operating voltage 385VAC Starting voltage 620V ?10% Remote terminal type normally open, normally closed, the terminal pressure / flow resistance: 250 V/1A Level of protection 2200V Leakage current 0.75 U1mA ≤ 20 uA ≤ 25 ns response time Power line access Traverse area ≥ 6 mm2 earthing ≥ 10 mm2 Ground Resistance ≤ 4 Ω Hoisted in the fixed installation on the wall or on the floor, Operating temperature range: -40 ℃ to 85 ℃ ≤ 95% relative humidity (25 ℃) Dimensions 350 * 250 * 95 Caution: 1.
