DD
A Din 96x48mm DC Ampere Hour meter, taking a current reference from a DC shunt and integrating this reference against time to achieve an Ampere Hour or Ampere Minute reading. There are two display screens, the main ten digit screen is the totaliser display, the other screen is a “Batch” programmable setting. The meter can be specified with up to four relay outputs (2C/O and 2N/O) which can be assigned at the time of ordering for many functions to control say an electroplating system. As an option RS485 MODBUS is also available. Three volt free control inputs are featured as standard for functions such as reset. Please discuss your exact requirements with our technical sales department.
