Product overview
-HFY-POWER intelligent DC panel POWER supply system is composed of high frequency switching POWER supply module and intelligent monitoring
- The product is suitable for power system, industrial users (petrochemical, metallurgy, railway), power plant, as a circuit breaker, closing and secondary circuit in the instrument, relay protection and emergency lighting to provide AC and DC power supply;
Suitable for hotels, conference rooms, hospital operating rooms and other places that need emergency power supply as a backup power supply.
Product advantage
- Multi-channel AC power supply, when the main power supply loses power, the standby power supply will automatically put into operation;
- Multiple high frequency switching charging modules run in parallel, N+1 thermal backup, high reliability;
- High frequency rectifier module, which can work independently or in parallel with multiple modules, can carry out online maintenance with electric thermal plugging, convenient and fast
- Extra wide voltage input range, strong grid applicability, can be used in relatively harsh environment
- Intelligent control of charging module, smooth adjustment of output voltage and current;
Self-flow sharing, good stability, high accuracy
- The monitoring system adopts touch screen or large LCD Chinese character display, friendly man-machine interface, intuitive and convenient operation
- Set the parameters of each part of the system through the monitoring module, easy to operate
- Open interface design, with powerful communication function, easy to realize the connection with substation RTU device, computer monitoring system, DCS
- Adopts the distributed monitoring system with the microprocessor as the core to realize the remote measurement, remote control, remote communication, remote adjustment and unattended of the power system
- Automatic management and protection of battery, real-time automatic monitoring of battery terminal voltage, charge and discharge current and automatic control of battery charging and floating conversion, with over/under voltage battery and charge over current sound and light alarm and temperature automatic compensation functions.
Ensure the battery works in the best condition to extend the battery life
- DC/AC AC/DC system integration (optional) : in the state of AC power failure, the battery can provide emergency AC/DC power supply for a long time uninterrupted
Function module

Host computer communication
- Provide RS232/RS485 two communication interface options
- Available in 1200BPS, 2400BPS, 4800BPS and 9600BPS four communication rates
- CDT451-91 and MODBUS protocol options are available
- The device's communication address can be set to any value from 01 to 99
> Support equipment
- Support various specifications of 5A and above rectifier modules
- Support comprehensive measurement unit ZHCL, battery inspection unit DCXJ, switch quantity monitoring unit KGL-52, insulation detection JYJC
- Support multi-group charger, double-group battery, multi-bus section system
> Other features
- With real-time clock display
- Access switching quantity monitoring can support two stage bus level 5 or 7 silicon chain control
- Access switch monitoring can support 12 system fault classification configuration output
- Can support two groups of 108 batteries patrol
- Can support two sections of bus 120 insulation branch detection
- Can support two sections of bus 120 feeder switch alarm detection
- When the system is normal and there is no keystroke operation for 3 minutes, the screen saver function will be automatically entered.But when the system fails or the battery is fully charged, the screen does not turn off
Product parameters
Conditions of use
- Altitude shall not exceed 2000m
- ambient air temperature not higher than +40 ° C, not lower than -5 ° C (average temperature within 24 hours not higher than +35 ° C)
- The humidity of the surrounding air should not exceed 50%. Low temperature allows a large relative temperature (e.g. +20 ° C is 90%). Consideration should be given to the effect of condensation caused by temperature changes
- Inclination with vertical plane is not more than 5°, and the whole group of cabinets is relatively flat, in line with (GBJ232-2) standard
- Requested in no violent vibration and impact, electrical components will not be corroded, no conductive dust place
