Making it more reliable than the general point flow screen system is more economical, but also saves floor space, reduce line losses and installation engineering, and easy to maintain, for the power supply system to provide new options for reliability. CYDY-300W / 220V DC power supply series of embedded devices using high-frequency power supply technology, automatic battery charging management module for maintenance, greatly extending battery life, making the device more secure and reliable operation. Device with communication, alarm function, you can easily achieve unattended remote automated management. Applications CYDY-300W / 220V Series Embedded DC power supply unit is mainly used in the various types of switching devices, the main switch (circuit breakers, load switches, etc.) and secondary protection device Model Description CYDY-300 / XXX Note: (CYDY behalf of the embedded power supply models, on behalf of continuous output power rating of 300 W, rated DC output voltage V), this device AC input voltage range; 85VAC-265VAC, DC output voltage of the device class: 220VDC / 110VDC / 48VDC / 24VDC Technical parameters 1, the use of environmental conditions working group of environmental temperature: -10 ℃ ~ + 45 ℃; maximum monthly average relative humidity: ≤90% maximum daily average relative humidity: ≤95% Altitude: less than 2000 meters. Working conditions: no conductive dust particles, non-corrosive metal box damage the insulation of chemicals, the use of location should have defensive rain, facilities snow, wind, sand, surrounded not allow full steam or a more serious bacterial pure cover in. 2, the input power supply AC input voltage: 85 ~ 265VAC Frequency: 50HZ ± 10% waveforms: sine waveform distortion <5% Power requirements: single no less than 150VA 3, the output power and power consumption (1) continuous operation power: Continuous Run: ≤300-600-1200W meet computer protection device, light, analog indicator power needs; when powered by a battery, the battery capacity and load parameters can be up to 8 to 24 hours. Short-run power: ≤600W, 20s meet VS1, VD4, ZN21 most 10KV system shells and other operating agencies breaker, electric power load switch storage needs. Instantaneous operating power: ≤1200W, 100ms. Meet VS1, VD4, ZN21 most 10kv system shells and other operating agencies open and close the circuit breaker and load switch power supply required; when powered by a battery back-up, operational for more than 20 times. (2) Power consumption: the power consumed by the device itself is not more than 12W. 4, battery charge and discharge device external 节 2 12V battery, AC power supply when the device power to ensure continuous DC power supply is normal, there are specific spare time battery capacity and load size determines when the battery discharge to over voltage, alarm signal devices and to protect the battery automatically stops the DC output; when the AC power supply is normal, the device automatically restore the DC power supply and the battery can be recharged within 72 hours. 5, the communication rate and communication rate 9600bps Statute Statute adopted MODEBUS communication protocol. Standard insulation properties meet the standards GB / T14598.3-93 of. The ability to adapt to a voltage dip compliance GB / T17626.11-1999 of. Electromagnetic compatibility: - insensitivity to electrostatic discharge provisions conform 3 GB / T15153.1-1998 of; - to power frequency magnetic interference insensitivity meet the three requirements GB / T15153.1-1998; - the right EFT interference insensitivity meet the three requirements GB / T17626.4-1998; - the high-frequency interference insensitivity comply with DL / T721-2000; - the insensitivity of the surge interference compliance with DL / T721-2000 of. Features 1, dispersed installation, save floor space, reduce the cost of embedded design ideas based on, CYDY-300W / 220V direct-current power supply series of embedded intelligent switchgear installed in the meter box (or the outdoor unit electric control box inside), you can save current screen area. Because the power in the switch cabinet, can reduce the amount of cable to use, saving time investment in equipment and cable construction work; in a little while the total number of units, the total price is lower than the DC-screen system, which reduces the total project spoil; while at runtime reduced spare parts, saving operating costs. 2, embedded power supply, greatly improve the reliability of embedded power supply, when a circuit fails, the other circuit is not affected power supply unit to avoid that failure-free operation of the station's power supply, and centralized power DC panel compared to the overall reliability can be greatly improved. 3, a variety of input and output for a wide range CYDY-300W / 220V series can provide DC 220v / 110V / 48V / 24V output according to customer demand, the AC input range of 85 ~ 265V, flexible and suitable for PT and mains supply. 4, intelligent management and maintenance of intelligent high-frequency power supply technology, self-testing, self-diagnosis, local display, alarm, can also be networked communications, get people unattended automated remote management. Built-in automatic battery charging management module, automatic intelligent battery management are floating, significantly delay the battery life, make more reliable and secure runtime
