The product must not be connected to circuits that have a maximum voltage above the continuous working voltage, relative to earth or to other channels, or this could damage and defeat the insulation. The product can only withstand transients up to the transient overvoltage rating without breakdown or damage to the insulation. An analysis of the working voltages, loop impedances, temporary overvoltages, and transient overvoltages in the system must be conducted prior to making measurements. Caution: When using insulated wires all wiring must be insulated for the highest voltage used.

No detergent or chemicals should be used. Temperature When multiple primary turns are used or high primary currents are applied the temperature around the transducer will increase, please monitor to ensure that the maximum ratisngs are not exceeded. It is recommended to have minimum 1mm2 per ampere in the primary busbar. Non-condensing 0.6 Advanced Sensor Protection Circuits “ASPC” Developed to protect the current transducer from typical fault conditions: • • Unit is un-powered and secondary circuit is open or closed Unit is powered and secondary circuit is open or interrupted Both DC and AC primary current up to 100% of nominal value can be applied to the current transducers in the above situations without damage to the electronics. Please notice that the transducer core can be magnetized in all above cases, leading to a small change in output offset current (less than 10ppm) Status pins When transducer is operating in normal condition, the status pins (3 and 8) are shorted. Status pins properties: - forward direction pin 8 to pin 3, maximum forward current 10mA - maximum forward voltage 60V, maximum reverse voltage 5V Accessories • • • 4-channel power supplies unit for connection up to 4 x DL2000 : 6-channel power supplies for connection of up to 6 x DL2000: Transducer cables in 4 lengths (2m - 5m - 10m –15m - 20m): Please visit the Danisense homepage for relevant datasheets. page 5 - 2019-11-05 Precision – Innovation www.danisense.com DSSIU-4-1U DSSIU-6-1U DSUB2 - DSUB5 - DSUB10 DSUB15 - DSUB20 DS50UB-1V (general tolerance 0.3mm unless otherwise stat- DSUB pin layout DSUB-9 pinout & BNC connection 5 4 3 2 1 When sensor is operating in normal condition the status pins are shorted. 9 8 7 6 5 9 4 8 3 7 2 6 1 Status pin properties. - Forward direction pin 8 to pin 3 - Maximum forward current 10mA - Maximum forward voltage 60V - Maximum reverse voltage 5V Positive current direction Is identified by an arrow on the transducer body page 6 - 2019-11-05 -Vc +Vc 0V Status Status NC NC Do not use Do not use Mounting instructions • Base plate mounting • Back side panel mounting Precision – Innovation www.danisense.com Impedance matching resistor 50Ω 1V 1 BNC 0V 2 holes 6.5 2 x M5 steel screws / 6N.m 3 holes 4.0 x 6H 3 x M4 steel screw / 4N.m DS50UB-1V Intended use: The DS50UB-1V is designed to measure current up to 100A., and be powered by a DSSIU-4-1U or DSSIU-6-1U. Instruction for use: 1. Do not power up the device before all cables are connected. 2. Only use cables supplied by Danisense 3. Place the primary conductor through the apperture of the transducer 4. If the DSSIU-4(6)-1U is intended for desk use, mount the rubber feet which are part of the package. 5. If the DSSIU-4(6)-1U is intended for Rack mounting, use the screw kit for mounting and do not mount the rubber feet. 6. Connect a DSUB cable between DSSIU-4(6)-1U and each sensor 7. Connect a Voltmeter, DMM or other sort of analyzer with a voltage input to the transducer BNC connector. 8. Ensure that no calibration connectors are attached when measuring primary current. Always avoid to create a calibration short circuit, between + and — calibration connection. 9. There is a risk of electrical shock if an uninsulated busbar with high voltages is touching the metal en- closure of the transducer. Please ensure before powering up the system that no primary busbar can touch the metal enclosure. 10. When all connection are secured - connect mains power 11. Apply primary current Safety Instructions: DO NOT TRY TO DISASSEMBLE THE UNIT. If the green transducer diode is not operating when the system is powered up, disconnect power and contact Danisense for further instruction.
