11 DT-FD SERIES DT-FD SERIES, HIGH VOLTAGE HV DC Current Transducer DT-FD series provide a large sensing window and the ability to monitor circuits with voltages up to 15 VDC. The sensor can be mounted on a DIN rail or be attached to a back panel with screws. Easily accessible power supply and output-signal, finger-safe terminals are located on the top of the sensor to allow for a clean and troublefree installation. The one-piece design combines the current sensing elements and the signal conditioning to provide an output compatible with most control systems, increasing the safety and accuracy of the installation. DC Current Transducer Applications Monitor Large Solar Panel Installations Large utility connected photovoltaic generation systems will often produce DC power at higher voltages as the wire can be smaller for the same amount of power produced. Monitor DC Motors Traction and drilling equipment use higher voltage DC motors to produce high torque output at low speeds. Solar Array Application Commercial and industrial ground mounted solar arrays are connected in series to combiner boxes, developing higher voltage and lower current to deliver the same power as with a lower voltage system. DC Current Transducer Features Industry Standard Analog Output Interfaces with PLC s, panel meters and data acquisition systems quickly, with simple programming by the installer. Compatible with most automation and control systems. Externally Powered VAC or DC (output not isolated from the power supply). No Need For Span or Range Adjustment Factory set calibration reduces setup time. Warranted to produce accurate signals for five years. (Our decades of experience designing and producing DC current transducers shows that the calibration stays accurate for many years beyond the warranty period.) Large Solid-core Case Sensing window provides ample space for single or multiple conductors. DIN Rail or Panel Mount Simply snap onto DIN rail or attach with screws to a panel.* UL/cUL Approved, CE Pending Accepted worldwide. *For information on the DIN rail accessories kit, see page 1.

15 DLT SERIES DLT SERIES DLT Series combine a Hall effect sensor and a signal conditioner into a single package. The DLT Series are designed to produce an analog ma signal proportional to the DC current in the primary conductor. These transducers are available in a solidcore or split-core case design. Lower current ranges make this sensor ideal for use in photovoltaic panel combiner boxes. DC Current Transducer Applications DC Current Monitoring PV Array combiner boxes. Wind generators. DC heating applications. UPS system monitoring. Photovoltaic Arrays PV Panel Current ma ma DC Current Transducer Features ma Loop-powered Output Industry standard connections, positive indication of correct field wiring. Single Range No chance of field range selection errors. Eliminates zero and span pots. Isolation Output is magnetically isolated from the primary circuit for safety. Eliminates insertion loss (voltage drop). UL/cUL and CE Approved Accepted worldwide. DC Current Transducer Output Solid-core Unipolar Output For additional Application Examples, go to Monitoring PV Arrays: The current produced by a photovoltaic module or array can be easily monitored by using the DLT series current sensors over the conductor exiting the collectors. Using a simple two-wire connection powered by VDC nominal in series with the sensor output, the sensor will produce a signal in real time that is directly proportional to the current being produced by the PV module. If a single cell fails, or a module quits operating properly, the current output will drop, and the current sensor will reflect the change. Safer and more stable than shunts, non-contact current sensors are a simple answer to measuring DC current at any point in the PV system.
