Picture of dc ammeter Overview of DC Ammeter

SPA-96BDA series intelligent DC ammeter adopts advanced microprocessor for intelligent control. The measured value can be directly displayed locally or connected to a microcomputer through an RS485 serial interface to form a measurement and control system. The meter also has two passive alarm contact outputs (upper and lower limits) that can be set arbitrarily. Some instruments also have analog signal output interfaces to facilitate connection with remote RTU.


Application fields of DC ammeter

* Solar photovoltaic power generation system

* Communication room power distribution

* Industrial DC control system

* Metallurgical industry, electroplating industry, electrolytic industry

* Wind power system

* DC excitation system


Function introduction of DC ammeter

* Four-digit LED digital tube display, current display range -1999 ~ 9999, decimal point can be set;

* Optional RS485 or RS232 communication interface (Modbus-RTU) protocol, device address and baud rate can be set by the front panel keys;

* The bus current level can be set directly, and the DC ammeter can be used for DC systems with different current levels;

* Auxiliary power supply can choose DC12V, DC24V, DC48, AC / DC220V or other special specifications;

* Optional up to two relay alarm outputs and one analog output

10Adc ,超出10Adc需加分流器或传感器 * Current: The maximum direct input current is 0 ~ 10Adc. If it exceeds 10Adc, a shunt or sensor is required.

* Light weight, beautiful appearance, easy installation and strong anti-interference ability.
