The Electronic Load Hardware Expansions Application Notes ZS PL H&H ZSLC Water-cooled ZSLV Low Voltage PMLI Multi-channel ZSAC AC NL Source-Sink Accessori es GPIB Interface Expansion 1) (Option ZS03) With the ZS03 option the device can be expanded by a GPIB interface. Simply insert the card. (Supplied without GPIB cable.) 1) 3) 4) Temperature Interface (Option ZS16) With the temperature interface card temperatures from 0...100 °C are captured by a NiCr-Ni (Type K) sensor and transformed into a 0 ...1 0 VDC analog voltage. This analog voltage can be fed to the analog control input of the Analog I/O interface and read out via the data interface. Data Acquisition Tool (Option NL13) 2,3) The Data Acquisition Tool adds the following functions to the range of the device: Fast synchronized data logging for waveform generation with data memory Exponential inrush processes 1) 3) Ethernet-RS-232 Converter (Option ZS15) Data is sent via the LAN card to the serial interface of the unit. Castors 1) (Option ZS09) Steerable castors can be screwed onto large devices for easier transport. A 19“ rack can then often be dispensed with. This option is available for devices from 5HU and is suitable only for hard floors. Electrically Isolated Analog interface 1) (Option NL06) In the case of potential differences between the negative load input and the signals on the Analog I/O Interface the standard Analog I/O card can be replaced with an isolated version. All measurement and control signals are transmitted via isolation amplifiers and optocouplers. The card is pincompatible with the standard Analog I/O card. The isolation voltage is 500 V DC with respect to the negative load input. Converter (in addition to 18 Bit standard A/D converter) Sampling rate, Synchronization Measured data memory 1) 3) Power I/O Card (Option ZS07) The Power I/O card can be expanded to control external devices. 8 relay contacts (N/O 125 V/1 A) can be actuated via the data interface and 8 logical inputs (5V ... 24V, shared GND) can be queried. The inputs and outputs are isolated from the load input. The isolation voltage is 500 V DC with respect to the negative load input. Fast A/D converter 13 Bit, measures voltage and current simultaneously min 200 μs, can be programmed separately for each wave section and synchronised with waveform generator 2,000 V/I value pairs with timestamp Software GTC Battery capacity test MPP Tracking for solar panel test Synchronized data logging with variable scanning rate for waveform. Simultaneous measurement of voltage and current. 1) Can be retrofitted at any time. 2) Can only be retrofitted or produced by H&H. 3) Requires ZS01 oder ZS02 4) Requires Option NL13 48
The Electronic Load Calibration Factory Calibration Certificate (Option FCC-NLxx) 1) A Factory Calibration Certificate (FCC) can be supplied with the devices. The FCC meets the requirements according to DIN EN ISO 9000ff. This calibration certificate documents the traceability to national standards to illustrate the physical unit in accordance with the international device system (SI). The recommended calibration interval is 1 year. We would be happy to calibrate your devices at regular intervals. Software Tools Control Tool (Universal Control Program) Tool supplied as standard can be used to control single device. Scope of functions: Device settings Data logging with numerical display Trigger source selection Activation of cut-off criteria Data logging Dynamic List and Data Acquisition Tool The Tool Dynamic List permits the intelligent generation of profiles in the form of straight sections. The wave trajectory can be graphically displayed before testing. The profiles set can be stored and re-activated when 1) Can only be produced by H&H. needed. If the NL13 option is installed, fast synchronous data logging can be carried out for the programmed wave trajectory. The measurement points can be imported directly after the end of the measurement.
