Low Voltage Switchgear
01
GZDW DC Power Supply Cabinet
Features
● The main monitoring system features a 240*64 dot matrix LCD with Chinese character menu display, operated via membrane keys.
● Measures DC bus voltage (main and control buses), battery current, and control bus current.
● Calibrates measurement/display values via software, eliminating the need for potentiometer adjustments.
● Integrates DC system bus insulation monitoring.
● Equipped with temperature compensation function.
● Supports single battery bank and single-bus non-segmented systems.
● Provides MODBUS protocol for backend communication, enabling "Four Remote Functions" (remote monitoring, control, adjustment, and signaling).
Operating conditions
● Altitude: ≤2000m
● Ambient Temperature: -5°C to +40°C
● Relative Humidity: ≤95% (at 20±5°C)
Note: For applications exceeding the above conditions, please consult our company for customization.
