KLS-3
KLS-3
Functions and features:
It is suitable for dc system under 100Ah, especially for open and closed stations and small user stations.
Three 5A/7A/10A modules can be installed, providing 220V/15A, 220V/21A, 220/30a or 110V/30A;
The monitor adopts LCD display, Chinese menu, keystroke operation and menu password protection, which can realize system parameter setting, system working parameter display, system fault indication and system calibration.
The detection of closing and controlling voltage, controlling current and battery charging current is completed in the monitor, without external wiring and external sensor connection;
Silicon chain voltage reducing automatic control function of monitoring appliance, which can realize automatic voltage regulating function of controlling bus only with manual silicon chain.
The monitor has the function of automatic battery management, can choose battery patrol instrument and feeder branch insulation monitor, with ac input voltage measurement function;
The monitor provides RS232/RS485 background communication port, and can choose standard MODBUS and CDT communication protocol.
