Technical indicators 1 2 3 System Features screen a DC power supply switching power supply system features a unique modular design, N + 1 hot backup. Wide input voltage range, power applicability and can be used relatively harsh environment of the place. Charging module can be hot-swap, line maintenance, and convenient. Low hardware difference between independent current technology, the module is less than the maximum output current imbalance ± 3%. System design using IEC (International Electrotechnical Commission), UL and other international standards, reliability and security have adequate protection. The monitoring module using a large-screen LCD display or touch screen, sound and light alarms. Monitoring module can be parameterized by the various parts of the system, user-friendly, easy to operate. Have a smooth adjustment of output voltage and current, battery automatic temperature compensation, and other advanced features. Open interface design, with powerful communications features, it is easy to achieve substation RTU device connected to a computer or power plant monitoring system DCS. Three Distributed monitoring system, power supply system, "telemetry, remote, remote, remote adjustment" and unattended. Automatic battery management and protection, real-time automatic monitoring of battery terminal voltage, charge and discharge current, and controls both the battery charge and float with battery over / under voltage and charge overcurrent sound and light alarms. 2 Technical indicators edit AC input voltage: 380V ± 15% (three-phase) power frequency: 50HZ ± 10% Power factor: ≥0.92 input overvoltage alarm: 437V ± 5V input voltage alarm: 320V ± 5V output voltage range: 180V- 320 continuously adjustable, 90V-160V steady flow accuracy: ≤ ± 0.5% regulation accuracy: ≤ ± 0.5% efficiency: ≥94% ripple factor: ≤0.1% output undervoltage protection: 196V ± 2V, 98V ± 2V output over voltage protection: 325V ± 5V, 162V ± 2V Relative humidity: ≤90% (20 ± 5 ℃) Insulation resistance: ≥10MΩ audible noise: ≤45dB Ambient temperature: -5 ℃ ~ + 45 ℃ mechanical properties: Dielectric Strength: Output on the ground, input to ground, input to output is applied 2KVAC time 1min no arc flashover Size: 2260mm × 800mm × 600mm 3 DC-DC power supply screen editing screen for power plants and substations in the power supply operation are employed today DC power supply and DC-screen is used to supply a DC power source such that the power to control the load and DC load and provide emergency lighting load power, is a contemporary power system control, protection and therefore the basis of a large number of advanced applications science and technology. It mainly consists of power line systems (AC line), Power Dual mutual investment system, charging machine control systems, battery chargers, DC distribution system, insulation monitoring system, integrated controller (system monitoring and control system for the DC panel's brain ), flash systems, communication systems, batteries these parts.
