GZDW DC Power Supply Panel

Product introduction    There is double AC power input way for the panel. One is the way for working power; another is the way for standby power. When the power fails, the system automatically switches to standby power. Automatic voltage converter: The panel automatically converts voltage value according to voltage of closing bus-bar. The panel uses a pressure relief device-level or pressure relief device. This work is stable and reliable. Multi-protection design: The panel has surge protectors which prevent over-voltage of the power supply. There are overvoltage protection, current limiting protection, short- circuit protection, module parallel protection, over-temperature protection and over-current protection system as a whole can improve the safe and reliable operation.   N +1 redundancy design: The charging module has N + 1 to improve reliability, the charging module has self cooling, supports live hot plugging-in and pulling, is easy to maintain.   Centralized Monitoring Function: Coordinate with the central monitoring or control of the DC power supply components and operating parameters of the role of the state, at the same time concentrate on each module
Parameters upward crew transmission, PC and transmitted under the order. Use of the structural design of building blocks, can lose control Level. All AC voltage, current, spare each other automatically switching; coordination or control supply bus-bar of current, voltage parameters. Battery voltage parameters, battery charge and discharge current parameters; system insulation parameters; reclosing switch monitoring, control switches, batteries Melting Off work for the state of insulation fed a control loop (optional); Patrol battery (optional), monitor the environment temperature.    Technical specification of GZDW DC Power Supply Panel   Rated input voltage: AC380~415V Range of input voltage: AC323~475V Frequency: 50Hz ± 10% Power factor: 0.92 Rated output voltage: DC110V or DC220V Range of output voltage: DC99~143V (DC110V), DC198~286V (DC220V) Rated output current: 10A~240A (DC, N+1) Equalizing coefficient: ≤ 5% Voltage stabilizing accuracy: ≤ 0.5% Current stabilizing accuracy: ≤ 1% Ripple coefficient: ≤ 0.5% Efficiency: ≥94% Noise: ≤50db (1m away from the panel) Product Process and Test Our workshop Clients visiting Shipping Certification Our factory   Company‘s Charitable Activities:     Notes for Placing Order         The customer shall specify the following items:
