CNW Series DC Power Supply System-Modular Assembly Telecom Equipments
Product specification
You are welcome to use the CNW series outdoor integrated power supply developed and produced by Shenzhen CONSNANT Technology Co., Ltd. The input power is 176Vac～264Vac, and the output power supply is -43Vdc～-58Vdc. It is a high-efficiency power supply device specially designed for 5G communication equipment. The IP protection level of the power supply equipment is IP65. It has the characteristics of integration, miniaturization, light weight, wide operating temperature range, long service life, green environmental protection, etc. It can be applied to indoor and outdoor distributed equipment of communication systems to provide high-quality uninterruptible power supply Ensure that 5G, 4G, 3G, 2G, WLAN, EPON and other communications fully cover shopping malls, stations, airports, parking lots, office buildings, communities and many other occasions.
Main technical features:
- Green energy saving: The rectifier module adopts the fully digital bridgeless PFC power factor correction technology, and the input power factor reaches 0.99, which reduces the pollution to the power grid;
- High efficiency: The rectifier module adopts bridgeless PFC, LLC, synchronous rectification topology, and the overall 1000W efficiency is >94% (full load); the module assembled 2000W, 3000W efficiency >95% (full load);
- Intelligence: The power supply device has a built-in wireless monitoring unit, which can realize full Netcom (4G standard) or NB-IOT access to the mobile monitoring network; it can connect to existing mainstream smart phones wirelessly or Bluetooth to display monitoring content;
- Simple: The interface adopts aviation connector, which has fool-proof operation, simple wiring and safe operation; after power-on, the device will enter the running state, and no other parameters need to be set. If you want to modify the parameters, you only need to use a mobile phone or computer to operate online;
- Strong applicability: It has IP65 protection level and can be used in various harsh environments. At the same time, the lithium battery is equipped with a heating film, which can be used normally at low temperature -40 degrees; It can be well used in anti-vibration environment;
- Easy maintenance: The integrated integrated power supply is composed of an upper cover and a lower cover. The power supply compartment and the battery compartment are designed separately, and are connected by an aviation connector for easy disassembly;
- Compatible with AC and DC input: In addition to AC, the input can also be connected to DC of 200Vdc ~ 400Vdc, which can also be used as a remote for some DC remote supply scenarios;
- Unattended: It has comprehensive protection function, alarm function and self-start function; through wireless transmission, the operating parameters and operating status of the power supply can be grasped in real time;
- The input and output have perfect AC and DC lightning protection design, suitable for areas with many thunderstorms;
- Perfect battery management. It has the functions of load power off and battery low voltage protection (LVLD+LVBD), which can realize temperature compensation, automatic equalization and floating charge control, automatic voltage regulation, battery capacity calculation, online battery test and other functions;

Installation and maintain
1) Installation
1. The power supply should be installed in a place with good ventilation, shade and good heat dissipation;
2. Keep a certain distance between the power supply and other equipment for heat dissipation;
3. Fix the attached mounting bracket or hoop on the micro power supply device.
4. Fix it on the utility pole or base station bracket by wall hanging, pole holding, flag installation and other installation methods (when installing, the incoming and outgoing wires should be facing down to better waterproof), and tighten the fixing bolts.
2) Maintain
| No. | Symptom | Cause Analysis | Approach |
| 1 | Voltage does not work after power on | Whether the input air switch or terminal has voltage coming in, and whether the voltage value is within the normal range | Check if the voltage at the incoming line is normal, confirm that the air switch is closed |
| 2 | Keep restarting after power on | The rear stage load is too large | Whether the output is normal under the no-load test, if the load is too large, some devices should be removed |
| 3 | Communication equipment does not work after power on | Communication equipment such as RRU is powered by -48V and must have correct polarity to work properly | Reverse output cable polarity |
